LOVE - In Search of a Reason for Living What is this book? This is a book about life, and a book about you. Its purpose is to send you on a journey through your heart, mind, and soul. If you take the journey you will find in yourself the reason for living. If you care at all about life and people and yourself, you will take the journey. The day you were born you began a learning process that will continue for the rest of your life. You were, from the beginning, molded by your surroundings, parents, relatives, playmates, by all the general attitudes, ideas, and beliefs you came in contact with. As you grew older those early experiences affected and altered, both consciously and subconsciously, what you felt and did about all the day to day things that went on around you. Each new year of life added to your past, changing the way you viewed every new day, influencing how you reacted to everything from the simplest daily routines to complex events touching you, your family, and the world you lived in. As you grew yet older you interacted with people from different backgrounds with differing ideas about life. You found yourself actively defending, modifying, or abandoning your early beliefs, adapting the various ideas you came in contact with to fit your developing perception of life. Perhaps new ideas were introduced to you by people with dynamic personalities who espoused one philosophy or another. Faced with the challenge of those ideas, you may have tenaciously defended your early beliefs, dismissing unfamiliar concepts with alarming ease by resort to ingenious, if not solid, arguments. On the other hand, you may have completely abandoned your past and adopted new beliefs opposite to those you once cherished. However, like most people, you probably belong to that vast river of humanity which seems to move along in a fairly discernible direction, concerned at any given minute with living that moment in the easiest, most pleasant way possible. If so, you were and are more or less able to blend ideas, feelings, philosophies, desires, and realities to justify what you want to do. Along with the majority of people, you were and are good at sending questions and ideas about the meaning of life and death, as well as thoughts and feelings about what is good and right, deep into the cloudy regions of your mind. Whether we realize it or not, most of us are voluntary prisoners of our minds, unwilling to question who we are and what we believe, happy to simply roll along through life. Most of us will live from birth to death in a world we have fashioned from our past to suit our present. Many will find comfort through unquestioned acceptance of their family's, or even a friend's, religious or philosophical heritage. Yet few will ever stand free from their present beliefs and daily lives to ask what is life about? Who am I? What should I do? What will I do? If there is meaning to life, and a reason for living, those questions must be answered. If there is a true meaning to life, nothing that you do, say, or think will change that truth. What good is it to live your life believing what you are doing is right if your beliefs are false and what you are doing is wrong? It is an understanding of life that we seek, a search for something in life worth living for. If you are to find the meaning of life you must be willing to recognize it if and when you see it. To do so requires you to open your mind and accept whatever you discover, even if it is totally opposite to your experiences, beliefs, and wishes. If you are to understand life you cannot hide in the comfort of daily living, clouding your mind to avoid discomfort. You must not reject what you discover if it does not fit what your life has been, is, and what you want it to be. Since our discussion deals with the purpose of life, if what we are saying is true, your willingness to understand is a willingness to grasp the very reason for your living. If the answers you find are different from those you have molded for yourself, you must decide whether to continue on the path you are on, or go another way on a new path toward a new destination. Warning! There is a risk that as you read our book, you may misunderstand the discussion and think that we are suggesting that there is no "reason to live". That is not what we are saying at all! In fact we are saying the opposite, we have abundant hope that if you search for the reason to live you will find it. As you read this book you must not become discouraged or depressed. If you are or become discouraged, if you disagree with anything that is said, or if you simply don't believe what we are saying is "useful" to you, please finish reading the entire book. Even if you agree with what is being said, and think you understand what we are talking about, please read every section, including the appendices. If you are to find the true reason for living it is necessary that you understand what is discussed in the last section of the book (before the appendices). We are convinced that after you read this book, from cover to cover, and complete your journey through your heart, mind, and soul, you will find in yourself the reason for living. Anyone who is, or becomes, seriously depressed should always seek immediate medical help. [If you find yourself distressed or depressed by our conclusions please read the note following the appendices.] IF YOU ARE WHO YOU ARE, WHO ARE YOU? Each of us is born, we live lives of various lengths, and then we die. Each of us has, or perhaps develops, a separate nature and existence, a being, which is unique to us and sets us apart from every other person who lives or has ever lived. Indeed we share similar characteristics, but no two of us are the same person. As humans, each of us is distinct, each of us is an individual being. What makes each of us unique is the fact that we perpetually make choices between alternatives. Our choices seem to be far more than mechanical selections based on some complex biological decision making scheme. Rather, your choice seems to be based not only on what you believe will happen if you make a certain choice, but also on what you "want" to happen. You, as all of us do, possess the ability to engage in what we will call “rational thought”, whereby each of us weighs many variables in a process that includes concepts of good and evil, right and wrong. “Rational thought”, as we define it, is reasoned thought that presents us with choices between alternatives. You ultimately reach a point in your rational thinking where that certain quality of being which is unique to you takes over and you make your free choice among the alternatives. Biologists have demonstrated that the line between animal and human "thought" is not as clear as was once commonly assumed. There are animals that appear to have self-awareness, solve problems, communicate, exhibit emotions, etc. While there may be a very high degree of intelligence in the animal world, animals seem to lack the ability to make free choices by consciously "thinking" about alternatives and consequences. It appears that only human beings possess the necessary consciousness and symbolic languages that allow us to engage in significant abstract thought. For example, animals may or may not harm other animals, yet they do not appear to be able to make reasoned choices to harm or not to harm by considering whether it is right or wrong to do so. An animal may make a “choice” to act kindly toward another animal based in part on their "inherent personality" and “basic instincts”. Yet it appears that an animal cannot make a rational, reasoned, choice to go against "inherent personality" and "basic instincts". Human beings can choose to do that which they would not otherwise do, to go against what their instincts, personality, and emotions tell them to do. Scientists often take this apparent distinction for granted. Rather than consider ourselves to be nothing more than highly evolved animals, we should recognize our ability to engage in "rational thought” and give more consideration to the fact that we appear to have truly unique mental abilities. Unlike any animal, your choices are made after rational thought. Even though you have instinctive feelings for self-preservation, procreation, self- satisfaction, etc., decisions may be freely made for reasons and purposes totally opposite to those instincts. You can think about what you are going to do, and can choose to do what you believe is right and good even if it places you in grave danger. Similarly, you can choose to do what you believe is wrong and evil even if you would instinctively do otherwise. Your decision is your decision, a product of your singular existence and being. Able to engage in rational thought, and to choose freely among various courses of action based on those thoughts, you are in a very real sense what you choose to be. One of the oldest controversies in human history deals with what the significance of rational thought really is. Perhaps the most debated question is whether or not rational thought actually gives us the ability to make “freewill” choices. Many scientists argue that every rational choice you make is in fact predetermined by your biochemical makeup. They admit that when you have a choice between two options you engage in both conscious and subconscious thought processes before making what you consider to be your decision. However they argue that no matter how convinced you are that your choice between A and B is your own, your brain chemistry actually dictates your selection. They suggest that your mind's decision-making processes cannot go beyond the level of chemical neurological activity. Therefore, even though your choices may in one sense still be said to be your own, they are in effect predetermined. Despite the agonizing doubts, careful thought, and numerous changes of mind that accompany daily decisions, most scientists believe the final decision would be totally predictable if they could decode your brain. This idea of "determinism" not only shows up in science, but in some ancient philosophies and religions as well. Taken to its logical extreme, many believe in super-determinism, where all that is in the universe was in the past part of a closely related system in which "matter and energy" were joined. Many scientists and philosophers view everything from sub-atomic particles to human beings as part of a universe whose destiny was forever set at creation by the forces between its constituent parts, and whose future unfolds in a billiard ball like progression of "predictable" actions. To this school of thought, humans are prisoners of subatomic laws that determine the behavior of atoms that determine the behavior of molecules that determine the behavior of nerve cells that determine the behavior of human brains that determine the behavior of human beings. Even though the chain is totally imperceptible to humankind, and a feeling of control exists as an inherent part of human existence, they insist that what seem to be "spontaneous" decisions and reactions are actually destined to occur without any possibility of variance. While most scientists are comfortable with the idea of an ordered and well-behaved universe, many view the complexity and reality of life as requiring events to be based on something less than absolute certainty. On the sub-atomic level this idea has been recognized in the so-called uncertainty principle. Those who accept the uncertainty principal might be called probability determinists. They argue for a determinism as certain as any, one that also sees humankind governed by forces beyond its control. Yet the reality dictated by their brand of determinism can only be described by stating how likely it is that a particular event, chosen from a list of possible events, will occur. In other words, they can eliminate what cannot happen, can give you a list of events that might happen, and can even tell you how likely it is each individual item will take place, but they cannot tell you which of the possible events will in fact occur. The exact future of the universe may be uncertain, yet it is still fundamentally predetermined. Modern theories dealing with chaotic behavior tell us that because of the almost infinite number of possible combinations created by the interaction between objects we cannot complete the necessary calculations to determine what will in fact occur next. Furthermore, some mathematical problems may have no solutions, and seem to be fundamentally “non- computable”. It is simply not known whether or not non-deterministic physical mechanisms exist in our universe. Virtually all of the currently “favored” cosmologic theories dealing with chaos, complexity, and computability agree that given enough information and processing power (even if the required amounts approach infinity) the probabilistic behavior of even the most complex system in our universe is "in theory" mathematically calculable. It is fair to say that all of the currently favored cosmologic theories conclude that our physical universe is, in some real sense, fully deterministic. In a universe that had no living organisms, determinism would not be as hard to accept as it is in our universe inhabited by living creatures. One can visualize a universe devoid of life where every rock, every speck of dust, every atom, every sub-atomic particle, follows a pattern which was forever fixed at creation, and which expands into the future with absolute precision. In an inanimate universe, it is not as difficult to accept that rocks, specks of dust, etc., or even groups of these objects, have no "ability" to alter the course that the laws of physics dictate they follow. It is much more difficult to accept that our universe, populated as it is by living organisms, is a totally deterministic one. If super-determinism is correct, we reach the intuitively unlikely result that the absolute time for every blink of our eyes is predetermined, every breath that we take is taken at precise moments and in exact amounts! There is nothing we can do to alter any of our physical motions - even the slightest twitch of our body occurs at the very moment it was destined to occur by the forces acting in the first second of the universe. Every change of our minds is inevitable, every thought we have ever had was predetermined and occurred without any chance of alteration. If we live in a fully deterministic world, I was destined before birth to write precisely the words contained in this paragraph on the day and at the time and on the computer I wrote them on, and when the universe was formed you were destined to read precisely the words contained in this paragraph on the day and at the time you are reading them. At the beginning of the world, not only were you predestined to be precisely where you are right now, but you were also destined to be wearing the clothes you are wearing, have every hair on your head the exact length that each one is, have every object in the room placed precisely where it is, etc. Every thought you are having about what I am saying was predetermined to occur without the slightest variation, even your instant reaction to this very sentence was set at creation. This simply does not "seem" to be what actually happens, we intuitively "feel" that we can make meaningful choices among alternatives, perhaps so, perhaps not. Even though current theories do not appear to allow for freewill, some scientists and philosophers argue that no matter how well ordered your chemical thought processes may be, you reach a point in each sequence of mental activity where the unique being which you are makes a decision. A decision that goes beyond the confines of conscious and subconscious biochemical processes. A choice made after "considering" the products of your biological thought processes along with abstract concepts of good and bad, right and wrong, etc. They believe the basic, profound aspect of human existence, which makes you who you are, transforms your choices among alternatives into "free will" decisions that transcend physical constraints. It is very difficult for those of us who have grown up in a scientific world to visualize, let alone accept, human thought extending beyond the chemical confines of the human mind. Yet there has been no scientific evidence (perhaps because no experiment has been devised that could test the hypothesis) that would refute the jump from predetermined biochemical thought to human thought controlled by individual beings. Because no one has explained the illusive quality that might make each human being unique and give them control over their decisions does not mean that it does not exist, nor does it mean it does exist. Some scientists and philosophers believe that determinism might be compatible with the existence of a physical, as opposed to a non-physical, consciousness that can be held to be morally responsible for its actions. It would seem that those scientists and philosophers do not adequately appreciate the fact that all the currently favored physical theories are based on fully deterministic causal relationships, be they probabilistic or otherwise, and therefore lack any mechanism for human freedom or responsibility. They incorrectly conclude that because complex physical systems exhibit almost infinite complexity, those systems might support some kind of metaphysical freedom. On close examination this is not justified, simply because in every accepted theory all observable physical systems, from Planck scale to the scale of the universe, are governed at every level by deterministic laws. The idea that a physical consciousness, based on deterministic physical processes, might make meaningful choices, seems both illogical and fundamentally wrong. Other scientists and philosophers argue that modern science has proven determinism to be "true". In fact, science has only begun to address the nature of human thought. On a sub-atomic level more questions have been raised than answers found, leading some to suggest that quantum effects may allow for free-will. Research into the nature of physical consciousness has demonstrated the incredible complexity, and fundamental mystery, of the human mind. Paradoxes associated with thought experiments suggest we have not yet begun to understand the basics of human consciousness and the possibility of freewill. Even if the human mind can make meaningful statements about its most fundamental nature (it is not at all clear it can), nothing to date either proves or rules out the existence of human freewill. For the moment we ask you to accept the possibility that freewill exists beyond biological and physical constraints. We note that no matter how predetermined your existence may be, it can be argued that "you" make freewill choices even if it is chemically determined what those choices will be, simply because "you" are the product of your biochemistry. While that argument, and variations of it, may be true by definition, it seems if we are to be held accountable for our actions we should have a freedom of choice that can be anticipated to be found only in that which is beyond human chemistry. We ask that you keep an open mind about the possible existence of individual control which makes your decisions truly your own. WHO WILL YOU BE WHEN YOU NO LONGER ARE? If in fact you do exercise meaningful freedom of choice, what good is it to be a unique human being if at your death you cease to exist? If you do not continue to exist in some form after death, what good are all the experiences, decisions, triumphs, defeats, all the moments of your life? If you do not survive the grave, if you return to the state of being that preceded your birth, then I suggest to you that nothing in fact does matter. While over the ages men and women have sought to perpetuate themselves through their children, their place in history, their role in society, and through intricate philosophical webs of existentialism and other essays on physical man's importance, the fact of physical death remains. If each generation's death means the end of those individuals, then we are all faced with an endless cycle of creation and destruction, the meaning of which, if any, is beyond comprehension. If there is anything in life we can count on occurring without fail, it is physical death. The successful bank president, the champion athlete, the housewife, the famous, the unknown, every human being, you, I, die. While all acknowledge the certainty of their eventual demise, few think about death until they are faced with it. The simple fact of death is not news to anyone, yet the reality of its impending occurrence is ignored by virtually every living person. The very nature of human life denies death and shrouds it in the cloak of future events, events that are not yet real and need not be dealt with in the present. Living is too important and time consuming to be concerned with mortality. The fact that you are moving steadily toward your death is most likely, and literally, to be the last thing on your mind. Observing the inevitable death of every creature that inhabits the earth, we may have a recurrent feeling that death is the end. On the other hand, it is virtually inconceivable to us that all we are, all we have been, all we will be, will be rendered void in that moment of death. It goes against human nature to visualize the effective destruction of our past, present, and future, which accompanies death without existence beyond death. Yet if each human being does cease to exist, then all human beings are, or in the case of generations yet unborn will be, waiting their turn to cease existing. If each and every human being ceases to be, then the feeling of continuity that pervades the human race is false (please note, we will explain later why we do not believe that life is in fact destroyed by physical death). In their arguments for humanism, existentialism, etc., philosophers have spent lifetimes trying to construct a difference between the apparent continuity of humankind, and the periodic death of individual humans. Most of us think of our ancestors as a link to the past, and our children as a link to the future, yet if we do not survive the grave each generation dies an isolated death that mocks any assertion that humankind has a continuing existence apart from its individual members. If each person's death results in their no longer existing, then no manner of historical recording, social progression, or other remembrance in the minds of those whose time to die is yet to come, can in any way affect, preserve, or make any difference whatsoever to those who no longer are. No one will survive to remember. If each of us ceases to be, then your life has no meaning and your choices make no difference. We admit that this logic seems counter intuitive, and even wrong, but if we are willing to dissociate ourselves from the incredible biologic urge for self-preservation, both of the individual and the species, and are willing to apply purely objective reasoning, the logical conclusion, while discomforting, is perhaps inevitable (there is at least one possible logical loophole we will discuss below that might give permanent meaning and value to a finite physical life). This is a very difficult conclusion to accept, it goes against our intuitive feelings about the continuity of human life, and against our assumptions that individual physical lives have some kind of meaning and value. Yet if we are little more than doomed animals, our intuitive feeling of meaning and value would not be surprising. From the very beginning, to assure survival of any species, evolution would certainly have instilled in living creatures the feeling that there is a reason for them to exist, a reason for them to crawl out of the ocean and build cities. If there is no life after death, and our lives are in fact consumed by "nothing", it is no wonder that our genetic heritage argues so strongly against that possibility. Because it is so difficult to accept, we will consider our conclusion in more detail. It is logical to assume that if each person's consciousness is the product of their physical bodies, then individual physical consciousness exists only during that person’s physical life on earth. If each of our physical lives proceeds from birth to death, then the consequence of each person's death necessarily follows their death. Who can be affected by that death? Certainly those who survive may be affected, but here is the "problem", the death cannot be of any consequence to the purely physical human being who no longer exists! The moment before the death of a human being perhaps it can be said that their impending death affects that being, but the very moment after the person dies, he or she is no longer around to be affected! Let us assume, for example, that a comet collides with the Earth at some time in the future before humans have colonized space. Assume further that all life on Earth is annihilated by the collision. It is very hard to accept, but if consciousness is nothing more than a physical phenomena, if there is no non-physical continuation of life after death, the most logical, I believe the only logical, conclusion is that the complete annihilation of humankind is of absolutely no consequence to humankind! While the words may sound bizarre and counter intuitive, in fact they are not. The moment after the total destruction of humankind it can be said with some certainty that the destruction of humankind had no affect whatsoever on humankind, simply because humankind no longer exists to be affected. If you accept that time has direction (we believe that even absent a “fundamental time”, all events follow a causal, sequential, chain), then cause and effect, action and consequence, occur in a fixed order, the former always "preceding" the latter. Keeping that in mind, the idea that after the total destruction of humankind there would be no one left to be affected should not seem as bizarre. Assuming that one event will always precede another event in order of occurrence, if the event that is called the death of a human being is equivalent to the physical annihilation of that human being, the consequence of that event necessarily follows the event. If there is a causal sequence to events, then the annihilation cannot be of any consequence to a human being who no longer exists. Again, the moment before the destruction of humankind perhaps it could be said that the impending destruction affects humankind, but the very moment after humankind is destroyed there is absolutely no humankind left to be affected. Assume that the comet annihilates humankind at 12:00 noon, the consequence of that destruction occurs at 12:00 noon PLUS a moment in time, and at 12:00 noon plus the moment in time there is no humankind left to be affected. Indeed, there is no humankind around that is conscious of the fact that the comet struck the earth! The same logic applies to the history of individuals not visited by a catastrophic event. If you believe that each human being is nothing more than an individual physical entity, and therefore that there is no life after death, then at the time of their death each human being experiences the identical individual annihilation that all humankind would experience together if the earth and its inhabitants were simultaneously "destroyed". If a human being dies at 12:00 noon, and there is no life after death, at 12:01 they are not "around" to be affected by their death. If an individual named Bill dies at 12:00 noon, at 12:01 Bill no longer exists to be affected by his death. If Bill is a physical entity that does not survive death, after 12:00 noon (i.e. - after completion of the sequence of causal events that precede Bill's death) you could search the entire universe for Bill and you would not find him (some readers are probably thinking that Bill continues to exist as his world-line even after his physical death, we will discuss that later). Bill's death occurs at precisely 12:00 noon. Not minutes, or even moments, later. If there is no life after death, the very moment after the event known as Bill's death, Bill no longer exists. After 12:00 noon Bill cannot be affected by anything, including his death. The logic goes even further. If you do not believe that human consciousness continues to exist after physical death, then death not only annihilates each individual's present and future, but also annihilates their past. Most people would agree that for an object to have a present and a future the object must exist. Yet many would make the distinction that while an object cannot have a present and a future if it does not exist, it somehow can have a past. It is clear that the present and future of an object are bound to the existence of the object, but so to is the object's past. Much of the problem lies in the popular usage of the words past, present, and future both to describe that which is part of an object (a "past" that belongs to the object, like a person’s memories that “belong” to the living individual from birth to death), and to describe the existence of the object from a third party's view (a “past” which is a chronological description of the object, like a photo album containing pictures of an individual who has died). It is a misconception to equate the fact that there is a "history" of all beings or objects that is set in the "past", with the statement that a being or object that no longer exists has a "past". The first idea simply states that the being or object existed over a finite period that is apparent to those who currently exist. The extension of the concept of such a history to the idea that somehow the object or being that no longer exists still possesses a "past" confuses the distinction these two words can convey. Once an object or being no longer exists it obviously has no present or future, similarly the object has no past. While it may be difficult to accept, a mountain that no longer exists has no past, present, or future for the simple reason that there is no such mountain. There is a current history of a mountain that once existed, but there is no mountain we can point to and describe the "past" of. This is far more than semantics. A person who lived a thousand years ago had a historic life that those who are alive can be conscious of, but the person no longer has a past that is their past, which they can be conscious of. The English language lacks the words that would make it easy to convey the difference between a “history” set in the past that is the sum of all lifetimes, and a “past” that is unique to and dependent on the existence of an individual life. Perhaps humankind has avoided the initially discomforting possibility of "finite pasts" by not distinguishing them from the infinite. Perhaps the majority simply do not accept the possibility of the perpetual annihilation of human beings. There are many arguments that purport to counter this logic, including assertions that a person's life before physical death has “existential” meaning in and of itself, yet all the alternative arguments are set in the time before death, within the causal sequence of events that precede death. Every humanistic theory is based on the biophysics of existence before physical death. We believe that none of the arguments adequately address the period after death (perhaps with the possible exception suggested by modern physics that is discussed below), and therefore none answer the question of how a person who no longer exists can have a past, present, or future? If death is the end of your existence, should you be frightened by the certainty of your destruction? If indeed you cease to exist, you need not fear death, for after your death you will feel neither pain, nor pleasure, nor peace, nor torment. "You" will no longer exist, therefore "you" will feel nothing. The resulting void is just that, a complete and total void. There is nothing to fear, for there will be no one to experience anything negative. There is nothing to look forward to, for there will be no one to experience anything positive. The only way you can visualize what is usually called a "nihilistic" death is to picture yourself after death as being in the same state you were in before birth (of course you were not really in any state at all). Trying to project yourself into the void that precedes life helps you understand the void that may follow death. This ultimate void would in a single moment consume your past, present, and future. No matter what philosophers may tell us, such a fate, while it would offer no hope, would leave nothing to be feared. Admittedly, our conclusions about physical death are totally opposite to our "common sense" understanding of life. Virtually everyone is certain, for example, that if they are eleven years old now, they have already experienced their tenth year of life, and nothing can take from them the past experience of being ten years old. It is this assumption, that our past somehow exists forever, that is at the heart of all humanistic belief systems. Indeed, belief in some kind of physical persistence of a human being's past is the only rational argument for the universal humanistic conclusion that even if physical death is the end, living a "good life" gives meaning and value to human existence. However there is a deep, deep, problem with the humanist's view. "Humanistic" philosophers seem to accept that human consciousness is purely physical in nature, and acknowledge the end of consciousness at physical death. Yet almost all modern humanist philosophers tell us that a finite life can have meaning and value. The problem lies in failure to accept the rational and logical consequences for each human being if individual consciousness ceases to exist on the physical death of the mind and body. All of the humanist philosophers either ignore or misunderstand what the future holds for us after physical death if we are nothing more than physical beings. Philosophers often speak of the void that would follow such a death as the abyss, the unknown, the approaching void, etc. All of these suggest that we are on a journey to a "place" which lies at the end of our physical lifetimes. If on our death we cease to exist, this idea that we are traveling to our ultimate destiny is false. What the philosophers are doing is giving substance to nothing. We are not traveling to an abyss, the void, or the unknown, for these words suggest that we are moving toward something. I recognize the seeming absurdity of the language, yet if on our death we cease to exist, then "nothing" totally consumes us. This is the heart of the problem, we cannot in any way whatsoever understand or visualize "nothing". The moment we attempt to comprehend or visualize "nothing", the comprehension or visualization interjects something into "nothing", preventing us from reaching our goal. When we define "nothing" we give it the quality of being definable, a quality that can only be given to that which is more than "nothing". Nothing might be thought of as the total absence of physical reality, yet even this assigns a definition to the indefinable. The moment we think about "nothing" we make it an object that can be thought about, we make it an object that can only be more than "nothing". The only way we can answer the question "what is nothing?" is to answer it by not asking it, for if we ask the question we destroy the answer. Most people fail to recognize the fact that "something" simply cannot comprehend "nothing". If we are no more than physical beings, and if “nothing” follows our physical death, then at the moment of our physical death, "nothing" totally consumes us. What does science have to say about all this? We need to recognize that the very difficult conclusions we reach in this section are not necessarily supported by conventional interpretations of general relativity and quantum mechanics. The current understanding that human being’s have of the physical universe is fundamentally incomplete. Early concepts of space and time as absolute metaphysical entities would seem to be fully consistent with our analysis. However, modern physics tells us that the universe is much more complex than it was once thought to be. At the start of the third millennium, it is generally accepted that we exist in some kind of four dimensional “space-time”. The mathematician Hermann Minkowski, who helped formalize the math of space-time, said "…henceforth, space by itself, and time by itself, have vanished into the merest shadows and only a kind of blend of the two exists in its own right." Space-time is essentially the history of the entire universe, containing every "event" that ever happens. A "world-line" is the history of an object / observer in "space-time". Each point on the world-line of a human being is generally thought to be a real physical event that represents a unique sequential moment in the life of that individual, from birth to death. Conventional wisdom is that the world-line of a human being is the "human being", so that human life is in some sense a permanent part of space-time. If this is so, perhaps we have a permanent physical past that is etched in the fabric of space-time. To see why we do not believe that science provides us with a physical past, we need to look at three interpretations of cosmologic theories. The first possible interpretation, the one that we strongly favor, brings into question the very nature of space-time. At first glance, the concept of a permanent physical space-time seems to imply that human beings have a physical past, present, and future. Most people assume that the math of space-time describes a permanent physical reality that surrounds us, a very real, very physical, space-time in which we exist. This may not be the case. The limited number of physicists who understand the incredibly difficult math, realize that the theory of general relativity tells us that the universe may be completely described without using a "fundamental temporal variable", without even defining what we call "time". The time we measure on a stopwatch that we use to clock a foot race is derived from comparing the motion of the runner from the starting line to the finish line with the motion of the hand rotating around the face of the watch. The time on the stopwatch is not, as Newton thought, a fundamental quantity in nature, rather it is a comparison of the motion of the person running down the track relative to the motion of the hands of the stopwatch. Therefore, we may be justified in concluding that "time" is derived from relative motion, but that relative motion does not necessarily require the passage of time. It may be true that “fundamental time” simply does not exist. This is a shocking idea for human beings who are confronted with the ticking away of years, days, hours, and seconds. Even so, if you think about it, a year is nothing more than the relative motion of the earth going around the sun, a day is the relative motion of the earth rotating around its axis, an hour is a fraction of the motion we call a day measured by a quartz "moving" in a watch, a second is very close to the relative motion of a beating heart, etc. We don't expect to convince you in a few paragraphs that time is an illusion, it took years of reading and thought for us to reach that conclusion, but we do want you to recognize that there is a strong possibility that fundamental time does not exist. If this is a correct interpretation of general relativity, it can lead to the conclusion that there is no temporality of any kind associated with our universe. There are extremely serious objections to this line of thought. In its most popular forms, the other 20th century revolution in physics, quantum mechanics, incorporates a fundamental temporal variable. Some scientists believe that general relativity will be found to be incomplete, and that quantum mechanics tells us that time does in fact exist. Other physicists agree that the universe lacks a fundamental temporal variable by which the universe evolves, yet they also believe that in some very real sense the universe exhibits fundamental "temporality". None-the-less, there are a few respected physicists who believe that we should accept what general relativity is telling us, that there is no fundamental temporal variable in the universe, and find a way to modify quantum mechanics to eliminate both "time" and "temporality" from quantum theory. Given the success of general relativity in predicting experimental results, we strongly believe that this is the correct approach. We are convinced that if and when physicists discover a broad model that incorporates both relativity and quantum theories, what is usually called a theory of quantum gravity, it will not have any kind of fundamental temporal variable associated with it, and we will find that the universe is fundamentally "atemporal" in nature. If the theory of general relativity is in fact part of the illusive theory of quantum gravity, and if we do in fact live in an "atemporal" universe, one extremely speculative result might be that physical events in our lives either exist, or do not exist. The statement that a point on a world-line exists in the universe may be false, true, false, with no sense that “false” is “before” or “after” true! If so, then it may be quite literally true that your tenth birthday does not exist, does exist, does not exist in the universe. Perhaps you believe that your tenth birthday is a permanent part of your past only because it is part of your current memories, not because it exists in some kind of permanent physical space-time. We need to emphasize that this is a very speculative idea, that at the beginning of the third millennium is considered nothing more than science fiction by most, perhaps all, cosmologists. If we live in an essentially "atemporal" universe, and there is no non- physical existence after death, we are convinced that physical death consumes each human being's physical past, present, and future. This is very difficult to understand and accept, yet the idea that there is no fundamental temporality, and that this fact leads to the annihilation of our physical past, intuitively appears to us to be the correct interpretation of our physical universe. When you finish reading this book you may have questions about some of our conclusions, especially about the very complex relativistic and quantum science behind this part of our book. You may want to obtain a copy of detailed notes and comments that we release from time to time (addresses are provided at the end of this book), where we try to present a broader picture of the foundation and logic that supports the conclusions. The reason that we end up relying on intuition, and cannot be more certain that our conclusions are correct, is simply because no one knows what physics will look like if and when relativity and quantum theories are united. Furthermore, there is no way to tell how long it will take to find answers to the basic questions raised by modern physics. Indeed, it is quite possible that we will never know the answers to many of our most fundamental questions. We believe that the universe is essentially atemporal, and that physical death annihilates our physical (but not any non-physical) past, present, and future, but we may be wrong! OK, let's say that you are unwilling to even think about "time" not existing, would the existence of "time" restore a meaningful physical past to your life? The second possibility we will look at is based on the fact that most popular interpretations of modern physics suggest that the physical existence of each human being somehow persists in space-time in the form of the individual's "world-line”. Classical interpretations often say that an object is the entire world-line of that object, or that a human being is his or her entire world-line, but they do not really explain what is meant by this. They do, however, almost universally conclude that each event in a human being's life exists as an event in space-time, so that if we could observe the point on a world-line that is the tenth birthday of someone who is now eleven years old, we would see that person experiencing their tenth birthday. We would not see a "copy", or a "repeat", of the particular day, we would see the person's tenth birthday as it is occurring, period! It would seem that this characteristic of all popular space-time theories leaves us without tools for building a rational model of a universe that contains a "conscious" world-line that is the "me" reading this book. Rather it tells us that there is, and always will be, a set of unique "me's" that somehow exist in space-time at every single event on my world-line. We might want to say that I am the "sum" of all the points, yet the assertion that a human being is his or her entire world-line, from birth to death, does not appear to be consistent with the general consensus that every event along a world-line has a singular existence that cannot be preferred over any other event on that world-line. The theory of relativity tells us that all of the laws of physics are the same for every inertial observer. If we live in a fully relational, relativistic universe, we simply cannot prefer observations made in the inertial frame of reference of one observer over observations made in the inertial frame of reference of any other observer, no matter where they may be “located” in space-time. An apparent consequence of this fact is that for one observer your tenth birthday occurs before your eleventh birthday, while for another (spatially separated) observer your eleventh birthday occurs before your tenth! Relativity tells us that both observers are 100% correct in their observations. The cosmos appears to be a very strange place! Classic interpretations imply that each individual exists as discrete human consciousness in the billions of discrete events located at every point along that individual's world-line. Some physicists describe this by saying that there are many "now's"; others say there are billions of approximate "isomorphs" of "me"; many claim there are billions of other worlds in which various versions of "me" co-exist; etc. It seems reasonable to conclude that modern physics tells us that if time exists, literally billions of discrete, very real, versions of each of us occupy space-time! This may seem like science fiction, yet surveys of theoretical physicists and cosmologists confirm that most believe we must adopt some form of many-worlds, multiple existence, theory. Remember, this is currently accepted as the most promising approach to the problems of space-time, and not merely a speculative idea. If there is a "me" that exists on my world-line for every event in my physical life, or if there really are an infinite number of parallel universes in which I exist, then there is no singular "me". Rather there are billions of isolated "me's" either lying along my world-line, or stuck somewhere in totally isolated universes. If the scientists are correct, it would seem to be impossible to find meaning and value for a singular "me" in the collective existence of each of the billions of instances of individual consciousness, no single one of which is the real true "me" who can live a meaningful life. All of the popular interpretations of relativistic and quantum theories seem to lead us to the same conclusion, if you do not have a single permanent existence, your life has no meaning and your choices make no difference to “you”, simply because there is no single physical "you" that exists before or after physical death (please remember, we believe that life has meaning and value). There is a third possibility, that the intuitive feeling human beings have that their physical past exists as a singular entity is based on some real, yet unknown, physical model of our universe. The intuitive feeling is very strong that our physical life makes a positive or negative contribution to human existence, and that our physical life is a permanent part of the physical universe. Perhaps there is some single physical consciousness that incorporates all of the events along our world-line, and that preserves our physical past, present, and future. We cannot rule out this possibility, if for no other reason than the fact that it is theoretically impossible to prove a negative. In other words, we might be able to prove that physical consciousness after death exists in the universe by observing it, but we can never prove that physical consciousness after death does not exist because we have not observed it (we will discuss this limitation in some detail a bit later in the book). The third possibility seems to require the existence of a physical consciousness that is not bound to events on a world-line. Some physicists suggest that consciousness has unique physical properties so that human beings become sequentially “aware” of events on world-lines that are essentially frozen in a “block universe”. Yet, as we have already said, in every currently popular physical theory the universe “evolves” as a sequential progression of space-time “events”. It seems intuitively true that if human consciousness is a physical phenomena, that can be explained either by current theory or by physical laws that are not yet known to science, it is in some real sense inextricably bound to each of these space- time events. It seems intuitively difficult, or impossible, to accept that such a dynamic physical consciousness could incorporate individual predetermined “block” events into a singular human being without violating the basic tenets of relativity. While it is true that a physical consciousness that is not bound to physical events might represent a unique singular existence, it is also fair to say that there is no known reason to believe that physical consciousness is not inexorably linked to individual physical events, making the third possibility seem to be almost an impossibility. There may be many “me’s” that are experiencing past events in the “past”, and I may have a memory of past events in the present, yet the intuitive conclusion is that my physical consciousness does not experience past physical events “now”. It seems intuitively true that if consciousness of past events can be lost when memories fade or are damaged, then physical consciousness has not incorporated those past events into a permanent singular “me”. Einstein only briefly addressed this matter when he said “An individual who should survive his physical death is also beyond my comprehension, nor do I wish it otherwise…. Enough for me the mystery of the eternity of life, and the inkling of the marvelous structure of reality, together with the single-hearted endeavor to comprehend a portion, be it ever so tiny, of the reason that manifests itself in nature.” It seems that if we are to believe that there may be some kind of singular physical (rather than non-physical) consciousness that survives physical death, then we must accept that there is some unique physical consciousness that is "me", that somehow incorporates all of the conscious events of my life, and that is not dependent on the continuing physical existence of my biologic body. While current interpretations of popular theories do not totally rule out the possibility of a perpetual individual physical consciousness, there is no known method that is both rational and realistic (i.e.- a theory that appears capable of modeling physical reality), to construct a physical (as opposed to a non-physical) model that preserves the singular human physical consciousness of an individual after the physical death of that person. Modern theories suggest the possibility that multiple instances of a physical “me” exist in space-time, but they do not offer even a clue as to how to unite all of those instances into a single physical “me” whose consciousness spans space-time. Indeed, current interpretations of quantum superposition seem to deny the possibility of a “single” physical reality in which a unique “me” might exist. I can visualize and accept a “non-physical consciousness” that survives physical death, yet I am unable to have any confidence at all in the existence of a singular “physical consciousness” that survives the physical death of a human being. To do so, it would seem that I would have to discover a new physical process that incorporates all the “events” in a human life, and that creates a unique, singular physical consciousness that continues to exist in space-time as that human being, or at least as something that we can call a singular past that belongs to the human being. This seems to me to be an impossible task. I may be wrong, yet I simply cannot find an accepted physical theory that supports a unified "physical" consciousness that survives physical death. Furthermore, I do not know of any credible objective physical evidence that such a “physical” consciousness might exist. I can say that after many years of thought I am thoroughly convinced that any attempt to construct a model of permanent physical consciousness does far more damage to the centuries of accumulated scientific knowledge, than does the acceptance of the possibility that a permanent non-physical consciousness may exist. We have concluded that no current, or reasonably foreseeable, rational theory provides us with a singular physical consciousness that continues to exist after physical death, so that a single physical "me" continues to exist after my death in my physical “past”. We have said that if we do not have a singular physical or non-physical consciousness that continues to exist after physical death, then those who believe in nihilism are probably correct, and some type of "nihilistic" void awaits all of us. It may be a true void, like the void that preceded our birth, or it may be a very strange void where billions of "me" merely co-exist. Whatever physical form it might take, it would seem to satisfy the definition of a "meaningless" void. A moment's comment on those who believe they may be able to physically perpetuate themselves through cryogenics, cloning, etc. If, we live in a constantly expanding universe, our universe will eventually return to a state of uniformly high entropy, so that the cosmos will become a hostile environment in which physical life cannot be sustained. If, on the other hand, theories that predict endless cycles of expansion and contraction of our universe are correct, nothing physical can survive beyond the next collapse of the universe a few billion years from today. While a physical end to all biologic creatures may seem absurdly far away, your great, great, great (to the 100th. power), grand-clone would find it frightfully real when the time came for their physical demise, a distant time from now which like all imaginable time is but a second in eternity. There is simply no cosmologic model that we know of that offers any hope for a perpetual, physical, human existence. Even if in some unknown manner multiple clones could survive in an ever-expanding universe, the idea that they are perpetual extensions of their donor seems less than credible, perhaps so, perhaps not. Such a perpetual presence seems to be more like an endless path of meaningless individual moments than a continuous meaningful existence. Furthermore, if there is no life after death, it would make no difference if an individual (cloned or otherwise) continued to exist, or "died" in one hundred years or in one billion years, because "death" would annihilate the individual's past, present, and future. If physical death annihilates all individual consciousness then there is no reason whatsoever to embrace cryogenics, cloning, strong artificial intelligence, or any other means of extending physical life. Since an individual's death would carry with it no possible consequence to that individual, there is no logical reason whatsoever for the living individual to avoid the "consequences" of death. If an individual no longer exists after death, that individual has no reason at all to feel anything positive, negative, or otherwise about death (or for that matter anything at all about life). Again please note, we do not believe that physical death annihilates individual consciousness, and we strongly believe that life does have meaning and value. What should our response be to all of this? We strongly believe that there is absolutely no reason not to live for the possibility that life has meaning and value. We think we are right about the transitory nature of physical consciousness, but we may be wrong. If our conclusions are wrong, perhaps we do in fact have a physical consciousness that survives physical death. If we are wrong, we may have a perpetual physical existence that gives meaning and value to our physical lives, even if there is no non-physical life after death. We will not pursue this possibility, yet you should recognize that it exists. If we are right, if our physical consciousness does not survive physical death, our death may mark the end of our existence. Yet if our physical consciousness dies, it is still quite possible that we will not face a "nihilistic" death. Perhaps we have a non-physical consciousness that survives physical death, and that gives meaning and value to our lives. We will consider this possibility in more detail as we continue our search for a reason for living. Beyond the human desire for meaning in life, we would suggest that the logical consequence of what philosophers call a nihilistic death, "requires" the search for alternatives to nihilism. Those who believe that the nihilistic void is approaching are, by the very nature of their humanity, required to search for something to believe in other than the void. While it appears to be impossible to scientifically prove that life has meaning and value, it is equally impossible to prove that life has no meaning and value. No matter what the person who believes that life is meaningless may believe to be true at any particular time in their life, the possibility always exists that he or she may eventually find true meaning and value in their life. There is no reason to be a "nihilist", no reason to believe that life ends at death. If nihilism is correct, if life does end at death, it makes no difference whatsoever if we believe it is correct, or not. If we believe nihilism is correct, and it is correct, that does not alter the void that would follow death. If we believe nihilism is not correct, and it is correct, that does not alter the void that would follow death. If we do not believe anything at all about nihilism, and it is correct, that does not alter the void that would follow death. Yet if nihilism is not correct, belief and/or faith in that which offers a reason for living may well be essential to our existence. If because we believe nihilism is correct we accept the void, and we are wrong, then we have doomed ourselves. If we recognize that the humanistic belief that there is no life after death leads to the nihilistic conclusion that the "void" will consume past, present, and future, then to escape the quicksand of nihilistic time we must search for alternatives that provide a reason for living. It is very important to recognize that nihilism can never lead to suicide, for nihilism tells us that if we do in fact live in a nihilistic world, nothing that happens in our lives, no matter how "badly" we may feel about it at the time, has any "real" consequence at all. It tells us that what we perceive to be the very worst events in our lives are no better, or worse, than any other events. I am absolutely convinced that the philosophical neutrality that nihilism demands, means that nihilism never suggests or supports suicide as an option for any human being. Furthermore, since it is absolutely clear that we may not live in a nihilistic world, and that nihilism may be wrong, there can never be any reason to terminate our life, risk the negative consequences, and abandon the possible positive consequences of living a meaningful life. We are a small part of the whole. Unless the answer is revealed to us by the whole, we can never know during our physical lives what really happens when our physical life ends. Life may have physical or non-physical meaning and value that we do not, and perhaps cannot until our physical death, recognize and understand. There is no reason at all to reject the possibility that each of us has some kind of permanent physical or non-physical consciousness. There is absolutely no logical reason whatsoever to reject the possibility that nihilism may be false! There is no reason whatsoever not to search for an alternative to nihilism, to explore the possibility of a permanent physical or non-physical consciousness, to search for a reason for living. There is absolutely no reason whatsoever not to live for the possibility, however remote you may believe it to be, that life has meaning and value. [If you find yourself distressed or depressed by our conclusions please read the note following the appendices.] IS THAT ALL THERE IS? If it is true that your existence ends with physical death, does that mean that your life is meaningless? As we have said, the answer is probably (but not “certainly”) yes. Therefore, is it true that your life has no meaning? The answer is a qualified no. If we are somehow more than our physical bodies, if we can exist beyond and apart from those bodies, then perhaps each of us survives physical death and continues to exist, in some manner and form, beyond the grave. If you are, or you become through living, a unique individual who possesses the ability to engage in rational thought and exercise freedom of choice transcending biological processes of determinism, perhaps you have an existence beyond your physical mind and body, perhaps not. Since the dawn of recorded history people have thought and written about existence beyond physical death. Some have suggested that extra sensory perception, premonitions, unexplained knowledge of past events, along with other similar and possibly real phenomena, are part of the world beyond death, perhaps so, perhaps not. Perhaps the unique being which each of us is, the present existence that makes your choices and your life yours alone, exists now and after your death in a realm beyond the physical, perhaps not. Perhaps that which you are survives like energy in a dimension coexistent with the physical world but beyond the constraints of space, motion, and time, perhaps not. Perhaps each of us continues to exist in a manner and fashion infinitely beyond our ability to imagine, let alone comprehend, perhaps not. A great number of people have spent vast amounts of time and effort studying all manner of phenomena outside everyday experiences. Many, most, or even all "inexplicable" events may be explained by future generations of scientists. The most amazing phenomena are not the dramatic events often attributed to the "supernatural", events which could as easily as not be emotional illusions or the consequence of known or unknown physical laws. What are amazing to me are simple occurrences that defy probability. We have all experienced, and therefore witnessed, baffling events that leave one with a feeling that their explanation may lie outside the realm of natural science. For example, most of us have thought about someone we have not seen for years, only to bump into them a few minutes later. Even more amazing are instances that may occur when we are facing major events in our lives, when we are in some way confronted by someone or something that leads us toward a “better” choice. When faced with such occurrences, I have often found myself with an “intuitive” feeling that they are in some non-physical sense “planned”, perhaps so, perhaps not. I have paid a great deal of attention to the kind of occurrences that are classified by scientists as "amazing coincidences". While most can be accepted as coincidental, some appear to be one in a million events that happen with such regularity that the odds against them being merely coincidental are incredibly large. It is impossible for me, in good conscience, to dismiss them as being nothing more than random events. Many appear to be “objective” phenomena, well suited to empirical study, that statistically support the conclusion that they are not the result of chance. I have little difficulty accepting that there are events that are in fact controlled by forces beyond our present knowledge. Indeed, I am convinced that there is a non-physical explanation for many events. If they are true phenomena, and not products of the mind, their very existence strongly suggests that there is a world which is quite real lying somewhere beyond normal human perception. A brief glance at, a fleeting contact with, what may be the world beyond the one in which we live gives a shocking reality to what we academically speculate about, or even faithfully believe in. Though we may profess to believe in that which we cannot see, we may also find ourselves surprised when our beliefs appear to be true. Possible contact with a world beyond human perception gives us a startling realization that we may be eternally subject to forces absolutely beyond our control, and leaves us with a chilling or hopeful feeling (depending on your view of your prospects if eternity exists) that death will not be a simple, restful, eternal sleep. None-the-less, a belief that we may have glimpsed the world beyond, no matter how convincing at the moment, is diluted over time. The human mind's natural presumption is against out of the ordinary observations that, by definition, provide infrequent reinforcement of beliefs. Of course, it may be true that "supernatural" events, though perhaps of great significance to the living, are nothing more than manifestations of physical and biological processes beyond our present ability to explain, similar to early civilization's attempts to explain through myths the phenomenon's of fire and lightening. If so they have no significance at all to the question of our existence after physical death. Yet it may be that they are images created by the overlapping of the current world and a world you will find yourself in after death. There is no present answer to the questions posed by what many perceive to be “metaphysical” events. Our discussion deals with what the meaning and purpose of life is. As we continue you will see that whether or not anyone has in fact witnessed supernatural phenomena originating from a world beyond the grave, though a question which peaks curiosity, is not an essential, or perhaps even an important, one. You will see that we don't need to look for metaphysical events in our lives to understand what life is all about. The significance of such events is beyond the scope of this book and is simply not necessary to our discussion. We will see that even if no one ever has had, or ever will have, any contact in this world with a world beyond the grave, it would not mean that such a world does not exist. We will explore in detail the possibility that we may continue to exist after death. At this point we ask that you keep an open mind about life after death. For now, please accept the possibility, however remote you may feel it is, that in some manner and fashion we continue to exist after our physical death. THE SEARCH FOR TRUTH If a scientist, philosopher, or anyone else tells you something is true, and in fact it is not true, it is not true. To say something is true does not make it true. Even though you are told something is true, if it is not true it is simply not true. On the other hand, if something is true it is true, even if you are told or believe that it is not. If something is true or false, it is true or false whether we believe it to be true or false, or have not thought about its truth at all. If we believe a lamp is on a table, whether we have any evidence it is or not, and it is in fact on the table, then what we believe to be true is true. If we cannot determine whether or not the lamp is on the table, that does not change the actual position of the lamp. Even though without evidence we cannot prove a lamp is on a table, if it is on the table it is there and our belief is true. Just because we cannot prove something is true does not in any way mean it is not true. Because we cannot prove, or disprove, we continue to exist after the death of our bodies does not mean that we do not continue to exist, or that we do. If we continue to exist after our physical death, then we continue to exist, and if we do not, then we do not. If there is no one in a forest to hear a tree fall, does the sound of the tree falling really exist? If there is no one to see a tree fall, does it really fall at all? "Does an event occur if there are no observers?" is a valid question that perhaps can be answered "yes" only if the observer not only sees the event, but also continues to exist forever beyond the time of the event. In other words, if only inanimate objects surround an event such as the turning on of a lamp, perhaps it can be said no event has occurred since nothing has been seen, heard, etc., to change. Similarly, if a living observer witnesses an event but at some later date the observer ceases to exist, what value was the observation? Of course the argument can be made that seen or not seen photons stream from a light when it is turned on. Furthermore, it can be suggested that once seen or heard an event has “actualized”. Much depends on how you define "event", but underlying the question is a troublesome perception that goes beyond semantics, a feeling that a world without permanent observers lacks anything similar to what we call "reality". Even though we disagree, some philosophers have moved toward the view that "language" is the unique factor which gives humans the ability to think thoughts, and that language is the only thing that distinguishes us from animals. They suggest that using language, our consciousness assigns the concepts of true and false to the things and events that surround us. Some of them believe that "truth" has no meaning outside the human mind, and, therefore, in a very real sense, that "truth" does not exist as an independent reality. I am not uncomfortable with the idea that in an inanimate universe "truth" may not exist, and therefore there must be an observer for "truth" to have meaning. However I am very uncomfortable with the suggestion that where a permanent observer does exist, "truth" is merely a creation of that observer's consciousness. If we survive the grave, we may well have a perpetual consciousness that can observe and remember the "truths" which surround us. Whether or not a lamp has been observed to be on a table, if the lamp is physically sitting on a table the very existence of permanent observers who could observe the lamp may give independent meaning to the statement that it is "true" that the lamp is on the table, perhaps so, perhaps not. If memories of human events die with each person, then events themselves become little more than transient observations made by the living. Yet if we survive the grave, it would seem that we would have a continuing consciousness that recognizes a real and fundamental difference between that which is "true" and that which is "false". For now, please accept the possibility that some things are either fundamentally "true", or not. If we want to consider in greater detail the possibility of our continued existence after the death of our bodies, we need to be able to make statements we can believe to be true. In our quest to find some meaning in life, we must develop some method of determining "truths" which we can have a fair degree of confidence in. To do so we first need to understand what it means to be able to "prove" something, scientifically or otherwise. Over the centuries the quest for truth has been refined into the process of scientific analysis. A brief summary of what has come to be known as the scientific method is helpful. Scientists observe what they want to study and record properties they believe to be relevant to their research. While some may have preconceived notions of what they will find, others begin the process of experimentation and observation without any idea what, if anything, they will discover. Even though they may believe they will achieve a certain result, scientists who do not approach every experiment with open minds are not scientists at all. After gathering what they consider to be enough information about an object or event, scientists sit back, study the data, and try to combine and organize the information to discover a pattern running through it. They look for a model that not only describes what they currently observe, but that also perfectly matches past observations. The resulting descriptions of the world around them are known as theories or theorems. These in turn can be used to predict what will happen in the future under the same or similar circumstances. Efforts to formulate theorems that describe observations would be in vain if the universe was made up of random events, occurring without reason or order, for then no one could say what will happen next. Of course, that appears not to be the case, as our universe seems to behave in a more or less ordered manner. As we have studied the cosmos in more and more detail, it seems to be true that (what one scientist called his "gut feeling") all physical objects comprised of matter and energy (which may or may not include all aspects of human "consciousness"), from the tiniest atomic particle to the largest system, behave according to some fixed set of laws. These laws can be thought of as if-then statements, which describe what will happen if a certain event occurs. For example, one of the well-known results of the law of gravity is that IF an apple comes loose from the branch of a tree, THEN it will fall to earth. For several reasons I regret using simplistic examples to make a point. Because of their simplistic nature, they tend to lessen the importance of the point being made. They narrow the reader’s focus from the broad, general truth of a statement to a specific, small part of the whole. Simple examples tend to be incredibly inadequate when used to illustrate complex feelings, beliefs, ideas, etc. Some people feel they are being talked down to, or think they already understand what is being said. They risk missing the deep significance that often hides within the example. On the other hand, simple examples can be used to bring a point quickly home, allowing us to bypass a good bit of background discussion and to explore at once concepts which are best understood when drawn rapidly and simultaneously into the mind. The dangers of simplistic examples can only be overcome by the reader who is aware of the shortcomings, and is willing to expand in their mind the examples so that the "profound" will not be misunderstood to be "simple". Back to gravity and the falling apple. The law itself basically states that objects exert a force on each other that attracts them toward one another, the strength of the attraction being related to their masses and the distance between them. The fundamental law of gravity was described by Isaac Newton after he observed that objects that are dropped fall toward earth. By repeating his experiment over and over again, by dropping object after object, Newton gained confidence what he theorized to be true was true, objects attract each other with a strength directly proportional to their masses and inversely proportional to the distance between them. Each successful test of Newton's theory of gravity made scientists increasingly confident the theorem was correct. Why should repeated successes, i.e. more and more apples falling off trees, increase the confidence of the scientists? Beyond the "common sense" feeling that repeated successes increase confidence in success, is there some "scientific" reason to be optimistic? Enter the world of statistics. Mathematicians have long recognized that the larger the sample that is taken from a group of items, the better able they are to predict what individual items are like in the group. The larger the sample the more confident they can be that a "strange" or uncharacteristic item will not be found. This is true due to the fundamental nature of the mathematics behind statistical inference. It is true no matter what the items being sampled are, so long as the sample is not biased. For example, if you randomly sample 500 apples out of a box containing 100,000 thoroughly mixed apples, and find not a single rotten one, a mathematician can tell you with a great degree of confidence what the chances are that none of the 100,000 apples is rotten. If you sample 1000 apples out of the 100,000, he or she can be more certain. After inspecting 10,000 apples, he or she can be even more certain. If 5 rotten apples are found in a sample of 500, or 45 in a sample of 1000 the mathematician can tell you how many rotten apples you are likely to find among the 100,000 apples. No matter what is in the box, whether it is 100,000 apples, 100,000 pencils, 100,000 transistors, 100,000 anything, so long as the items are uniformly mixed, anyone can tell by drawing a random sample how many of the items in the box are likely to have one or more traits in common (i.e. color, size, shape, etc.). The bigger the sample, the more accurate the prediction and the more confident the predictor. It should be emphasized that the predictions are accurate not because of the nature of that which is being sampled, but because the mathematical relationship between the number of samples and the number of underlying items being sampled is fixed and predictable. If you draw at random four pencils from a jar containing 100 pencils, three are white, one is red, there is a certain probability that the jar contains 75% white pencils and 25% red pencils. If you draw four golf balls from a jar containing 100 golf balls, three are white, one is red, the same probability exists the jar contains 75% white golf balls and 25% red golf balls. If the apples in our apple barrel were not uniformly mixed, and/or the sample was drawn in some organized pattern, we might get only good apples, or at least a higher number of good apples than we would otherwise. The sample would be unrepresentative of the contents of the box and useless to the mathematician. It is very, very important to realize if we take as our sample 99,999 out of 100,000 apples and find not even a single rotten one, we can be incredibly sure we are right when we predict the one apple left in the box is not rotten. None-the-less when we examine the one remaining apple it may in fact be rotten!!!!! A LAW IS A LAW UNTIL IT IS NO LONGER A LAW What we are building up to is the fact that the law of gravity is called a "law" because, in billions and billions of observations, not once has any documented event occurred where two objects did not attract each other in precisely the way predicted (we now know that gravity may not behave exactly as Newton thought, but like Newton predicted, objects do attract one another in the sense that the theory of general relativity tells us that the gravitational effect moves objects toward one another). We can say with an absolutely incredible degree of statistical certainty that the gravitational "force" between two objects will always cause them to be attracted toward one another. At this point in time there is probably less than one chance in l,000,000,000,000,000,000 x 10 raised to the 1,000,000,000,000,000th power that gravity will not act essentially as expected. Yet, despite the incredible certainty of gravity, we do not and cannot know whether it is or is not possible for one contrary event to occur, and thus for the law of gravity to be proven wrong! I am not suggesting the law of gravity is incorrect and that an event whereby it is proven wrong will ever occur. In fact I would be surprised if any of the basic scientific laws of the universe are fundamentally wrong. What I am saying is no matter how many times something has been observed to be true, no matter how incredibly unlikely it is an unexpected event will occur, we have no way of knowing if such an event is possible or impossible! If the unexpected event is not possible, it will never occur, and it will never be observed. If the event is possible, and if it does occur, then it has happened, period. We must remember it is not the "law" which makes objects behave in a certain way, fundamental forces far beyond human comprehension do that. Rather the law describes the behavior and remains valid and true only until a single unexpected observation proves it wrong. Actually the law remains only apparently valid and true, if it is later proven wrong its former truth was an illusion. The law was in fact always false. "Modifying" a theory to better fit the observations does not help render the original theory true, rather it creates a new theory that is itself either true or false. Since scientific theories are tested by observation, they are true if and only if each and every event they describe and predict, from the beginning of the universe to the end, in fact occurs exactly as expected. Theories, no matter how solid they might seem, must be discarded as false the very first time they fail to describe real events. Science is based on observation, formulation of theories, and more observation. To observe necessarily requires the ability to perceive - to sense, feel, smell, touch, taste, see, hear. Early humans used all their senses to explore the world around them. When human senses proved inadequate, they devised better and better tools and instruments to extend their range. Microscopes and telescopes to expand vision, stethoscopes and amplifiers to increase hearing, plus thousands of other sensitive devices to enhance the senses. The catalog of devices used to expand our human senses is enormous and growing by the minute, yet all the instruments of humankind can do no more than extend the reach of humans into the universe of which they and their instruments are a part. We know of three spatial dimensions, height, width, depth, and a forth dimension, time (which may also prove to be spatial in nature). Space (height, width, depth), and “time” all exist together as space-time and cannot exist alone. Is there a fifth, a sixth, a seventh, an eighth dimension? No one knows, for if they exist they appear to be separate and beyond human ability to sense, measure, and thus scientifically prove. Does that mean those dimensions do not exist, the answer is no. Mathematicians and physicists use formulas to describe sub-atomic phenomena (e.g. - string theory) that can be interpreted as happening in multidimensional space. If a fifth dimension exists, it exists. If a fifth dimension does not exist, it does not exist. This is true regardless whether we can, or never can, observe that dimension and, of course, is true for any sixth dimension, seventh dimension, eighth dimension, etc. It is important to realize that no matter how many dimensions are eventually observed, one or more additional dimensions may or may not exist beyond human ability to observe. Many of you are saying to yourselves it is one thing to say that a dimension beyond human ability to observe may exist, but an entirely different thing to say that one probably does. You are right. Most of you will go on to say it is highly improbable, maybe less than one chance in a trillion, that even one more dimension exists beyond the observable number of dimensions, however many that may eventually prove to be. If you think that, you are wrong. To be able to statistically predict the likelihood of an event happening we must first observe to see how often the event occurs during a given period of time. If we cannot observe the event when it occurs, we cannot determine how often it happens (or conversely, does not happen) and we cannot predict the likelihood of the event. One problem with recognizing the limitations of statistical analysis is understanding the difference between not observing an event where the event watched for can be observed, and not observing an event where the event cannot be observed because it is beyond human ability to sense. The first, not observing an event which could be seen, leads to the statistically valid conclusion that the event is unlikely to occur. The second, not observing an event which is beyond human ability to perceive, cannot lead to any conclusion at all about the reality of that event. Yet it appears to be human nature to assume that things which have never been observed do not exist, or at best are highly unlikely to exist. If something exists beyond human perception it will never be observed during our physical lifetimes. If you cannot measure something because it is beyond human perception you cannot prove it exists, on the other hand you cannot prove that it does not exist! More importantly, you cannot say that it is statistically likely or unlikely that it exists. You simply cannot say anything objective at all about that which is beyond human ability to observe. It is very, very important to realize that it is absolutely impossible to say that it is either likely or unlikely something exists beyond human observation. We simply cannot determine in any way the probability that something exists, or does not exist, beyond our observable universe. To understand the significance of this often overlooked statement is to understand that we have no idea what, if anything, lies beyond our cognitive boundaries. A moments thought should bring the realization that this absolute limit of statistics and science renders all "scientific proof", as well as subjective feelings, that nothing exists beyond our perception into feeble "philosophic arguments". Despite what science might claim to have "proven", and despite what we might "feel", about what lies beyond our ability to observe, we cannot say anything objective about that which is beyond human perception. We may create mathematical models of what should lie somewhere just beyond observation, yet without a means of testing these projections they can never be more than idle speculation. We simply cannot say that it is likely, or not likely, that a "world" or "worlds" exist beyond the physical world in which we live. From an analytical standpoint anything, or nothing, may exist beyond human cognition. Human beings are limited to observing the effects of fundamental forces on matter and energy, and must draw conclusions based only on such observations. We can never "view" the forces themselves, forces whose metaphysical existence and purpose transcend human observation and comprehension. One of the consequences of being only a small part of the universe in which we live is the absolute fact that, unless revealed to us by the whole, we can never know if something or someone exists beyond the limits of our senses. No one, not you nor I nor the smartest person on earth can determine whether or not anything exists beyond that which we can observe. It follows that we cannot know if someone or something beyond our ability to perceive can and will alter the laws which govern our world. The significance of the continued possibility that an unexpected event will occur to disprove even the best of theories, and the very fact such a possibility will always exist, renders it impossible to "prove" anything to be absolutely true or false. Since even the most incredibly supported "laws" are always subject to being disproved by the happening of a single contrary event, all laws and theorems and common sense proofs are subject to being disproved. Fundamental precepts that apples fall, water flows, fire burns, may all be disproved by future events. Our limitations not only prevent us from exploring that which is beyond human perception, but also add to all human observations a degree of uncertainty that cannot be overcome. We can never say with total certainty that anything is true, or for that matter, untrue. In this age of science it is hard for those who have not studied the scientific method in its most intricate details to understand that, because it is a tool of human beings, it is necessarily limited in its application by the limits of human comprehension and understanding. It is even harder to accept that, since we are only a part of the whole universe, we can never determine by ourselves what the entire universe is like. A part of something never knows what the whole is like unless the whole makes itself known to the part. We can never know what is true unless the truth is revealed to us. Being a part of the whole means that every law we construct must be built from unprovable assumptions, assumptions that may or may not hold true in the future. We can never know if something, or someone, outside our perception, perhaps greater than the whole, will alter all or part of what we observe, rendering untrue in an instant the very best of our proofs. Of course, if underlying forces do exist, are not changed, and require the predicted behavior, then the laws never can and never will be disproved. However, that does not alter the fact that it is, and always will be, beyond human ability to "prove" anything. There is absolutely no way human beings can determine if fundamental forces exist that will never change. We simply cannot determine if it is possible, or if it is not possible, for a contrary event to occur. We can never be certain that contrary events will not happen, we can never prove that anything is absolutely "true". YOU CAN'T BELIEVE YOUR EYES We must be sure of observations that are within the bounds of human perception, and skeptical if what we observe appears to be opposite to that which is predicted. Yet we must also be willing to recognize and accept valid experimental data that disproves popular theories. Scientists have declared many theories to be true and elevated them to the status of "law", only to discover that future observations, often more accurate than the first, proved them wrong. There are millions of examples of these errors. Perhaps the most famous was the early contention that the earth was flat, a scientific "fact" based on observations that appeared sound to early scholars, which should not be so surprising to those of us who live in hilly country without a visible horizon. What all of us, including scientists, must be aware of is the ease in which we convert our theories into laws. Even if we believe our minds are open, most of us grab onto favorite theories and assumptions. We think of, and talk about, them as though there is no doubt they are true. We should take a minute to discuss the potentially "seductive" nature of misinterpreted or misused "scientific proof". A portion of my high school biology text described the propulsion method of certain one-cell microscopic animals (protozoa) through water by declaring they waved a tail like projection back and forth. The book had been careful to label many new ideas as theories, but stated this particular description in absolute terms since these one-celled animals had been observed for many, many years always moving in exactly the same way. Anyone reading the text would believe, as scientists and everyone else did, that there was absolutely no question how the animals got around. As I was watching television almost ten years later I was surprised to hear of an accidental discovery by a scientist looking at some protozoa. Trying to hold one still under a microscope he held down the tail with a needle. Instead of the body of the animal thrashing back and forth as it should have, he observed it to be spinning around the tail. The tail was attached to the body by what was in effect a small rotating joint, which acted like an electric motor spinning a propeller. Looking more closely, the scientist discovered the tail was in fact shaped like a corkscrew. Because the microscopic view had always been two dimensional, rather than three, the corkscrew motion looked down on from above had appeared to be that of a wave. Since it was common to find waving tails in larger animals, and since no one had predicted, let alone observed, a 360 degree rotating joint, the thoughts and conclusions of generations of scientists had been colored by conscious and subconscious assumptions. What had been accepted as true turned out to be false. But remember, what was found to be true had in fact always been true. Similarly, I remember reading an article by a learned scientist who was upset when a well-accepted theory was challenged. He noted that of course it was a theory, just as all scientific laws are really theories, but he then stated that the particular theory was so well documented it was obviously true. It was and is not "obviously true" for, as we have seen, no theory can be said to be unquestionably true. The theory was the theory of evolution. Darwin's theory has become for many the shining example of humankind's ability to pull itself out of the dark ages, and thus is cloaked in an emotional blanket that associates all criticism of it with attacks on science. To the religious fundamentalist evolution is a tool atheists use to infiltrate the minds of children. To the humanistic scientist, evolution is a symbol of the triumph of scientific reasoning over myth. To most people, perhaps, it is simply a more or less correct method of describing the seemingly natural progression of things. I have little trouble with the idea of either accepting or rejecting evolution, for I can take it or leave it as a part of the physical explanation of the universe which neither conflicts with, nor supports, religion or science. I would be quite surprised if the theory of evolution, in some form or another, is not essentially correct. What is troublesome is that challenges to evolution, and other theories scientists adopt as scientifically "self-evident", are often viewed as a return to the "irrationality" that preceded science. As such they are rejected without consideration as unworthy intrusions into pure science, which will go away if ignored. Many scientists simply will not talk about anything that upsets their idea of reality, yet all theories do just that. When any theory is first proposed, it is by its very nature an extension of humankind's knowledge (whether such knowledge is illusory or not), and as such goes beyond the then accepted view of the world. So long as such extensions are orderly and slow there is no problem, but when they leap ahead into the future they become the immediate concern of scientists who wish to keep science "pure". There is a strong presumption that something that has not been proven is somehow less than true. To many people the unproved is not simply unproven, but is "fantastic" and worthy only of the title "science fiction". Thus despite professed neutrality on the untested, many scientists have made it clear they are ready to label as absurd that which is significantly outside common experience and which has not been subjected to empirical scrutiny. If popular theories do not withstand future scientific challenges, recognition of their weakness will be slow to come, and acceptance of more exotic alternatives will be resisted with cries that the alternate theories are irrational myths. One should feel uneasy that correct theories, which are not subject to easy testing, might be dismissed as absurd. If something is currently "unproved" it may well be rejected by scientists as an impossibility, no one beyond the person postulating the theorem may dare dream of its truth. As we have already noted, in addition to rejecting that which may be proved in the future, many scientists are equally willing to reject as an impossibility the existence of that which is beyond human perception, and thus "unprovable". No matter what we may think, or intuitively "feel", we absolutely cannot say anything objective at all about the "unprovable". The as of yet "unproved", as well as the "unprovable", may, or may not, be "true". We should note one type of statement, the definition, which can be viewed as an irrefutable truth. By definition, water "boils" at 100 degrees Celsius. You can always define something to be what you want it to be, yet no matter how you define an event you will not alter the physical reality that makes up the event. Water "boils" at 100 degrees because we have defined what water does at that temperature to be "boiling". The word "boiling" is nothing more than a description of what happens at a given temperature. As a definition it is a label, which has nothing to say about the physical laws that affect the water. Nothing assures us water will continue to act like it does when it gets to 100 degrees. If in the future the behavior of water changes, scientists must either continue to label the new activity as "boiling" by broadening the meaning of the word, or must coin a new word to describe the changed state. If water would solidify instead of vaporizing, scientists could continue to define the new behavior as "boiling" and no one could say they were wrong. Yet the new state would be totally opposite to the old, only the name would remain the same. Fortunately most observers recognize a responsibility not to use language to define away challenges to their beliefs, therefore they create new words to label new events. The thing to remember is that definitions do not explain or alter the underlying reality. REALITY IS UNREAL We know science cannot tell us anything about the world beyond our perception. What then can it tell us about the reality that surrounds us? Is it able to give us a sturdy foundation on which to build our lives? Can it answer our daily questions? We will explore a bit of modern physics to see just how stable, or unstable, science really is. The information in this section is based on generally accepted theories at the time of writing, please note that by the time you read this book these theories may have been replaced by equally exotic scientific descriptions of reality. No matter what millennium you live in, you will be able to discover and recognize the absolute limits of science. If we are to accept our observations of falling apples as proof of the law of gravity we must first assume several things, for instance, that our eyes accurately perceive the motion of the apple, that our ruler accurately measures the distance the apple travels, and that our watch correctly records the time it takes for it to drop. If confronted with the question "does the ruler you are using shrink and grow if you look at it while moving at different speeds?", most of us would laugh and say to ourselves of course it doesn't, a fixed length is what makes a ruler a ruler. We would think the person asking the question would have us questioning whether the apple is real. Indeed I would have you question all "scientific facts", for a scientist named Einstein shook the assumptions about distance, time, and space that scientists had relied on for thousands of years. In his theory of relativity he "proved" the length measured on a "perfect" ruler and the time measured on a "perfect" clock vary according to the relative motion of one object to another. Because the change in length and time is unbelievably small where relative speeds are slow, as in the case of a falling apple observed by an earthbound viewer, we can ignore the affect of relativity on everyday life. None-the-less the effects are real and sensitive instruments have confirmed them. Because our eyes cannot measure any difference does not alter the effect. The affect on a ruler becomes so great when relative speeds approach the speed of light that what was measured to be a foot would actually become a millionth of a millionth of a millionth of an inch. Time is also affected by relative motion. If an identical twin could travel to another planet and back in a spaceship that flies at speeds approaching the speed of light, on return to Earth the space traveler would find that he or she had aged much less than his or her sibling. Perhaps the astronaut who left at age fifteen would be only twenty years old when he or she returned, while the earthbound twin would be ninety! This is not science fiction, the radical results predicted by relativity have been confirmed by countless experiments, including experiments where atomic clocks placed in jet planes ran slower than their earthbound counterparts! Here is another example of an everyday "fact" taken for granted as being absolutely true. What is the shortest distance between two points? Without hesitation the answer for many, many years was "a straight line". The theory of relativity tells us the universe may be shaped like a piecrust with bumps and valleys. Thus the shortest distance between any two points in the universe, whether it is between towns on earth or stars in space, must be drawn on the surface of the lumpy crust (the area outside the crust is outside the universe and does not exist) and, therefore, must be slightly curved! The curvature is so infinitesimally small it cannot be easily observed, none-the-less the shortest distance between two points may be a slightly curved line! Over the last few decades, some of the things which have been discovered are that energy and matter are different forms of the same thing (energy = mass times the speed of light squared); the speed of light is constant and nothing can go faster than that speed; as matter approaches the speed of light it becomes infinitely massive and shrinks in its direction of motion to become infinitely small; and at the sub-atomic level matter is neither a particle nor a wave but is incomprehensibly both. There are several excellent books written for non-scientists that explain relativity and other topics in modern physics. Another foundation of modern science, quantum physics, appears to offer a description of reality that is radically different from the one relativity gives us. Laws that operate at the subatomic "quantum" level provide probabilities of observing one of many possible results instead of giving a single observable solution to a problem. Quantum mechanics is a relatively new branch of science developed to explain why subatomic particles do not behave according to the Newtonian and relativistic laws that describe the behavior of "normal" size objects. Just prior to the time subatomic particles and events were first measured, physicists had declared that, with very minor exceptions, all the fundamental forces and laws of the universe had been discovered and described. When scientists started to apply the traditional laws of physics to nuclear reactions they were literally amazed to find that the laws did not work! The search was on for a way to modify Newton's and Einstein’s laws to explain the new phenomena. At the time no one knew the explanations would shake the very foundations of western knowledge. Light is made up of energy in the form of "photons" which have mass (in motion) and which behave like particles, SOME OF THE TIME. The rest of the time photons behave like waves of energy, similar to ocean waves. If you will think about an ocean wave you will realize water making up the wave simply moves up and down, not forward. Only the wave itself moves forward. Thus if a boat is sitting a mile from shore, each wave will cause it to rise and fall, but will do little to move it toward shore. The boat will move a bit as each successive wave exerts a slight pushing force in the direction of the shore, but the boat won't be carried to shore by any one wave as the wave itself sweeps toward land. The vast majority of the water is simply moving up and down, while only the wave moves forward. The problem occurs when you try to measure photons using different tests. Some tests detect "particles" of light hitting targets while other tests detect "wave" interference when light passes through narrow slits. Back to the ocean example, when two ocean waves meet they either cancel each other if the trough of one overlaps the crest of the other, OR they reinforce each other when the crest of one joins the crest of the other, forming a single doubly big wave (or any combination in-between can occur). When two waves interact they are said to be interfering with each other. The problem is a particle CANNOT act like a wave and a wave CANNOT act like a particle, yet photons act like both! The solution of modern physics to this apparently unsolvable problem is to say that photons are neither waves nor particles until they are measured, and that the measurement itself determines the nature of the photon. In other words, it is the measurement of the event that determines the nature of the event. To some degree this phenomena can be said to express hidden problems with what reality really is. In a sense physics is not able to describe the "reality" of an individual photon since it appears to have two inconsistent, coexistent, yet separate, natures. To the extent the point at which a photon is measured (known as the collapse of the wavefunction) can be considered an "event", an unsolved dilemma occurs in determining when the event "actualizes". If light is both a wave and a particle until measured, is it "truly" a wave (when measured as a wave by an interference experiment) at the point it interferes with itself, or at the point it strikes a photographic plate, or at the time the film is developed, or at the point a human observes the final picture, etc.? The answer is simply not known. One of the greatest philosophical shocks of this century came in the form of the Heisenberg uncertainty principal. As far as many philosophers were concerned the last straw was when, to help explain the observed phenomena, Heisenberg noted that if you measure the momentum of one of the particles ("momentum" is velocity, which is speed in a given direction, times mass) that make up an atom you must in some way affect its position. For example, if you measure the momentum (or velocity, the uncertainty principal is equally true for both momentum and velocity) of a subatomic particle by "observing" it move over a given distance, the observation alters its position in some unpredictable manner. Similarly, if you measure position you must alter momentum, thus at any given moment you CAN NEVER measure both the exact momentum and exact position of a subatomic particle. The more precise you are in measuring momentum, the less precise you will be about position, and vice versa. The problem is actually more than a problem of measurement, to be more accurate, the wave function of a subatomic particle (which describes the particle at the quantum level) that has not been "observed" is precisely determined (without using probabilities) by a formula known as Schrodinger's wave equation. However, the very moment you attempt to measure the momentum or position of the particle, the wave function collapses, introducing probabilities into the equation, and the exact momentum and position of the particle CANNOT be determined. Heisenberg's theory can be interpreted as supporting the proposition that at the quantum level the very concepts of momentum and position have no real meaning. At the level of measured observation, modern physics can tell you how many particles in a group of particles have certain momentums and positions, and how many have other momentums and positions, but physicists CANNOT tell you what the momentum and position of any one particle is. This failure is far more than just some inability to measure momentum and position, it is due to the fact that it is fundamentally uncertain what the momentum and position of any single observed particle is! A single particle when measured simply does not have position and momentum in any normal sense of the words, but members of a group do, and the probability of x number having x momentum and x,y,z position can be precisely computed! One interpretation (there are others) of this finding is that nature appears to determine the behavior of its "particles" by a flip of a coin. Einstein spent the latter part of his life attempting to disprove this disturbing idea, it flew against his concept of the universe and prompted him to say, "My God does not throw dice". Yet he was unable to disprove quantum theory in general, and the uncertainty principal in particular, both of which have correctly predicted every subatomic event that they have been tested against! To emphasize the significance of the uncertainty principal remember it says that the uncertainty about momentum and position is not due to limitations on humankind's ability to make measurements, but rather is based on the apparent fact that when observed the momentum and position of an individual particle is fundamentally uncertain. Of course, future physicists may find an underlying set of rules that can be used to predict the behavior of individual particles, or may discover a fundamental unified law which is consistent with the observed behavior. Einstein's discomfort may well have been the result of human limitations on his understanding of God. Even though many questions remain unanswered, repudiation of the uncertainty principal, however comforting it would be to philosophers, seems uncertain at best. One current theory, which we mentioned earlier, that is popular among cosmologists and that would eliminate the uncertainty, shows just how confusing and exotic the universe may be. The truly wild (and from some scientists' points of view, virtually unbelievable) "many-worlds theory", suggests that every time an event occurs which has a possible required alternative, the universe splits into two identical parts, except that in one universe one alternative occurs, while in the other the other alternative occurs. According to this theory (or at least to the most popular interpretations of it), there are potentially an infinite number of identical, except for the required alternatives, versions of each of us living simultaneously in different worlds. Uncertainty is eliminated because every alternative is guaranteed to occur. Rather than being a model of reality, this idea may be a product of human limitations. If you want some more disturbing news I can give it to you. There is a controversial extension of quantum physics that deals with the problem of "locality". Components of atoms have a property called "spin". Spin is one of the fundamental quantities in the universe that must, and we do mean must, be conserved. For each particle that possesses positive spin, there MUST exist a particle with negative spin. When two such particles fly off in different directions from an atom, they always have opposite spin. So far, no problems. We can "entangle" the particles and change the spin of one of them. The very instant we do so the other particle's spin changes, no matter what the distance is that separates them! Physicists, who accept that a problem exists, are at a loss to explain how a particle in a different location without any means of communication knows what another particle's spin is. It is a mystery how one particle knows to change spin at the very instant the spin of the other particle is altered (experiments seem to confirm the phenomena, however there may be a hidden variable that would explain the observations by extending current theory). Einstein believed that any "rational", in the sense of "objective", description of nature is incomplete unless it is both a local and realistic theory. A theory is "realistic" if a particle has "intrinsic" properties that exist even before they are measured. A theory is "local" if measuring the properties of one particle cannot affect the properties of another, physically separated particle, in a length of time that would require "communication" between the particles that is faster than the speed of light. Yet quantum "entanglement" of spatially separated particles may require that realism, or locality, or both, be violated! One highly speculative explanation of entanglement eliminates the normal assumption of "locality", the assumption that events occur at one specific location in the space-time continuum. If it is possible to have a rational description of the universe without a local theory, then you can have events that appear to be occurring in different locations actually occurring in the same place. Thus, no matter how far apart they may seem to be, two particles could know each other's spin because they are, in some as yet unexplained manner, in the same "location". Perhaps the two particles occupy the same position in some unknown dimension where there is no such thing as separation. Speculation about the significance of lack of locality is really unproductive, except to note that lack of locality could help explain premonitions and extrasensory events. Other complex examples of conflicts with accepted concepts of reality, truth, and classical philosophy and logic, are found within the fascinating, unsettling, discoveries of modern physics. We are left with fundamental paradoxes, the solutions to which are totally unknown. Indeed, despite what we are told by many scientists, it is not at all clear to those working at the leading edge of scientific inquiry that an objective physical description of the universe actually exists. The destruction of traditional concepts of time, space, matter, energy, of life itself, is both frightening, and hopeful. Given the dramatic efforts of modern physics to unravel the mysteries of the physical world, coupled with the possibility of the discovery of theories that better explain space-time (or atemporal space), perhaps even the discovery and/or existence of other "dimensions", all manner of extraordinary event may eventually be explained. Yet it is also possible that, despite appearances to the contrary, the universe does not have an objective and/or observable fundamental physical nature, and that no explanation is possible. Again we need to remember that all theories owe their credibility to repeated statistical successes. Even in the case of generally accepted physical laws, like the ones we have just discussed, one observed deviation would result in the probability of the theorem being correct going to zero. When a theory is for the first time shown to be false it is not merely more likely to be false, IT IS FALSE. On the other hand, the more observations reported which confirm the predictions of a "law", the higher the probability is that the law is true. No matter how many observations are made, the possibility will always exist that the law is in fact false. A brief comment on the creation of the universe and the laws themselves. At the time this book was written it was generally accepted that all of space-time was created at or near a point in time popularly known as the "big bang". By the time you read this, science may have discovered a better description for the beginning second of the cosmos, but the possible implications of current knowledge are too interesting not to mention. Entropy is a measure of disorder. If a glass of milk turns over, the milk will pour out onto the table, yet one will never see milk flow from a table back into the glass. This is because the entropy (disorder) of the system tends to increase over time. Another example, you may pour cream into your coffee to lighten it, but the cream will never remove itself to make the coffee black again. As a rule, complex systems tend to become more disordered over time. The universe we live in is a place of amazingly low entropy, were it not so we would not be alive. Each of us is an example of a highly ordered, low entropy, system. Every star, planet, rock, tree, living creature, everything in the universe that is more ordered than the diffuse interstellar gas clouds that surround us, is an example of a system with varying degrees of low entropy. It is generally accepted that for our universe to have the extremely low entropy it now has required as the "starting point" at the big bang the selection of a virtually infinitesimally tiny volume of the total phase space of all possible universes (phase space is a complete mathematical description of any physical system). To be more exact, the universe we live in apparently began at a point constituting approximately 1 part in 10 raised to the 10th power raised to the 123rd power of the entire phase space volume of all possible universes! This is a deceptively large number, which in fact cannot be written out! If you tried to write it out by writing the number "1" on a piece of paper, you would have to write a 0 on every single atom in the universe just to approach the number of zeros that follow the one, even then you would not be close to writing out the entire number. This amazing requirement for the initial condition at creation suggests that the odds are no better than 1 in 10 raised to the 10th power raised to the 123rd power that the universe in which we live was created by random chance. If the math holds true, and this interpretation is as logical as it seems, it may mean that the chance that the universe was created at random is about as close to impossible as one can get! Perhaps so, perhaps not. Many find comfort in believing that, even if science has not yet discovered all of the laws, every physical event from creation onward evolved according to a set of absolute physical laws. The mathematically precise physical structure of the universe, the tiny place we have in the incredible vastness of space, the biologic characteristics we share with animals, etc., all may be interpreted as evidence of a purely mechanistic process that governs our lives. Yet if we consider the complexity of that which we observe, and if we are honest with ourselves, we cannot escape the intuitive feeling that there is an "order" in the chaos that cannot be explained by science. Even if the odds against the random selection of the total phase space of all possible universes that is required for the observed entropy are not quite as impossible as they seem, we simply cannot ignore the intuitive feeling that the odds are almost infinitely against the random creation and existence of all of the following: a) matter and energy and the physical laws that govern them; b) the expansion of the universe from a tiny speck to the vast expanse which we see today; c) the defeat of entropy and the combination of matter and energy in exactly the right way to form every object in the universe; d) inanimate chemicals structured in precisely the correct way to create "life"; e) biologic processes that give the human species consciousness at a level that supports rational thought; etc. Think about this for awhile. No matter how strongly we may feel that life is the result of physical processes only, if we are objective we must admit that it intuitively seems virtually impossible that a purely random physical process could create the almost infinitely complex, yet extremely well ordered, low entropy, universe in which we live. While it seems that the underlying laws of the universe could not have been created by chance, I have no explanation why it also often appears that the observable physical universe deterministically evolves according to complex statistical laws. I don't know why reality is such that life appears to many as nothing more than a complex, biologic process, riddled with physical imperfections. I am not willing to say with certainty that the universe does not appear to exhibit many of the characteristics of a physical entity devoid of the non-physical. None-the-less, I am convinced that there is little, perhaps no, objective statistical support for the conclusion that the world in which we live is the result of purely physical processes. No matter how hard we might try to ignore them, we are confronted by astronomical odds against random selection of a set of initial conditions that could create a low entropy universe that exhibits the complexity of our universe. We are faced with a mystery that, if we are honest with ourselves, at the very least leaves us with the possibility that the observable physical universe is not "all there is". It is very, very, important to understand that, no matter what you may have been told or what you may think, no human being has any idea whatsoever what the fundamental physical nature of the universe really is. The consensus is that our universe began as a single, almost infinitely massive, almost infinitely small, "speck". As of this date, no one has been able to comprehend, let alone explain, the mechanism during the microsecond of the Planck epoch that allowed the universe to expand from a dot smaller than an atom, into the billions upon billions of stars that fill our universe. Anyone who takes the time to try to visualize billions of stars bursting out of a pinhead, will realize the impossibility of making "sense" of what appears to be a scientific fact. No one has a clue how to understand the reality of a quantum particle that is quite literally "everywhere" at the same time. No one knows how the "action at a distance" that relativity suggests cannot occur, actually does occur, if it really does. No one knows how to define or quantify "human consciousness". There is only one scientific deduction we can be relatively certain of, and that is that human beings do not know and understand the fundamental nature of physical reality. What all this tells us is that we have no real idea at all what the true nature of our life on earth is, or what the possibilities are for our continued existence after death! We are so much a part of the tiny portion of universe in which we live that we seldom realize the significance of our limitations. Instead of viewing our lack of knowledge as profound and exciting, we tend to accept with curious apathy that there may be far more to our existence than we know. At this point in our journey I am not trying to suggest that anything exists beyond our perceived universe, nor am I trying to suggest that nothing exists beyond our known universe. I am not suggesting if we survive the grave we will find ourselves in some dimension beyond the one we can sense and measure during our physical lives, perhaps so, perhaps not. Nor am I suggesting we can never sense and know about that which lies beyond the grave, if anything, until we experience physical death, perhaps so, perhaps not. What I am saying is scientific study and statistical analysis are absolutely limited to that which we can observe and measure. The absence of scientific proof does not make it less likely, nor make it more likely, that something, which is true and real, lies beyond human observation. The important thing to remember is that no matter how likely or unlikely you "FEEL" it is that something exists, if it is beyond human ability to observe, you CANNOT "KNOW" if it is likely or unlikely that it does exist. This is true for the probability of the existence of life after death. From a scientific standpoint we simply cannot say it is likely that life after death exists. It is equally true that we absolutely cannot say it is likely that life after death does not exist. While scientists may offer attributes of physical death as proof that human beings do not exist beyond the grave, the real answer to the question lies beyond human ability to scientifically prove, one way or the other. Indeed, we cannot say anything objective at all about the possibility of life after death. If life after death does not exist, it does not exist, period. If life after death does exist, it does exist, period. Many of you will read what we have just discussed, agree with it, and then let it fade out of your mind as you move on to whatever comes next. If what we are saying is true, it is fundamental and “profound”. Perhaps it will be important and helpful to you later on when we discuss what may be the most important choice in your life. For this reason we urge you to think carefully about what has been said, being certain you understand what we are talking about. WHY? Before leaving our discussion of the scientific method, we should note the interesting, apparently absolute, limit whereby the question "how" becomes the question "why". Let's jump ahead 10,000 years, and assume that a unified field theory has been discovered. A unified field theory is a theory that describes the behavior of all forces and elements according to a set of fairly simple laws. If and when such a theory is "proved" we may in fact have succeeded in explaining the past, present, and future behavior of all observed matter and energy. However the ultimate questions will remain. Why were the unified forces that control energy and matter created? Why do they exist? Who or what is the source of such primordial forces if they are the most fundamental of forces? These will still be unanswered, and it is not hard to see, will remain unanswerable. Science will have succeeded in fully describing the forces seen in nature, and their effects on matter and energy. The question "how" forces work will, for the most part, have been answered. But an explanation of the creation, the existence, the source of the forces, the answer to "why" such forces exist, will be missing. The ultimate question, "WHY?", most clearly defines the limits of science and human beings. Without realizing it, we constantly bump against this invisible wall that surrounds us and limits our knowledge. We know that the force of gravity causes objects to be attracted to each other, but why is this so? Think about it a few minutes. Obviously gravity needs to exist to prevent objects from flying apart, but why not have a gravity that is half as stro
