A New Theory of the Universe

 A New Theory of the Universe

Neuroscientists believe that the problem of consciousness can someday be solved.  Science has not succeeded in confronting the element of existence that is at once most familiar and most mysterious—conscious experience.  As Emerson wrote in “Experience,” an essay that confronted the facile positivism of his age: “We have learned that we do not see directly, but mediately, and that we have no means of correcting these colored and distorting lenses which we are or of computing the amount of their errors.  Perhaps these subjectlenses have a creative power; perhaps there are no objects.”

Biology is at first glance an unlikely source for a new theory of the universe.  But at a time when biologists believe they have discovered the “universal cell” in the form of embryonic stem cells, and when cosmologists like Stephen Hawking predict that a unifying theory of the universe may be discovered in the next two decades, shouldn’t biology seek to unify existing theories of the physical world and the living world?  What other discipline can approach it?  Biology should be the first and last study of science.  It is our own nature that is unlocked by means of the humanly created natural sciences used to understand the universe.  Ever since the remotest of times philosophers have acknowledged the primacy of consciousness—that all truths and principles of being must begin with the individual mind and self.  Thus Descartes’s adage
:Cogito, ergo sum.” (I think, therefore I am.)  In addition to Descartes, who brought philosophy into its modern era, there were many other philosophers who argued along these lines: Kant, Leibniz, Bishop Berkeley, Schopenhauer, and Henri Bergson, to name a few.

We have failed to protect science against speculative extensions of nature, continuing to assign physical and mathematical properties to hypothetical entities beyond what is observable in nature.  The ether of the 19th century, the “spacetime” of Einstein, and the string theory of recent decades, which posits new dimensions showing up in different realms, and not only in strings but in bubbles shimmering down the byways of the universe—all these are examples of this speculation.  Indeed, unseen dimensions (up to a hundred in some theories) are now envisioned everywhere, some curled up like soda straws at every point in space.

Today’s preoccupation with physical theories of everything takes a wrong turn from the purpose of science—to question all things relentlessly.  Modern physics has become like Swift’s kingdom of Laputa, flying absurdly on an island above the earth and indifferent to what is beneath.  When science tries to resolve its conflicts by adding and subtracting dimensions to the universe like houses on a Monopoly board, we need to look at our dogmas and recognize that the cracks in the system are just the points that let the light shine more directly on the mystery of life.


The urgent and primary questions of the universe have been undertaken by those physicists who are trying to explain the origins of everything with grand unified theories.  But as exciting and glamorous as these theories are, they are an evasion, if not a reversal, of the central mystery of knowledge
: that the laws of the world were somehow created to produce the observer.  And more important than this, that the observer in a significant sense creates reality and not the other way around.  Recognition of this insight leads to a single theory that unifies our understanding of the world.

Modern science cannot explain why the laws of physics are exactly balanced for animal life to exist.  For example, if the big bang had been one
-part-in-a billion more powerful, it would have rushed out too fast for the galaxies to form and for life to begin.  If the strong nuclear force were decreased by two percent, atomic nuclei wouldn’t hold together. Hydrogen would be the only atom in the universe.  If the gravitational force were decreased, stars (including the sun) would not ignite.  These are just three of more than 200 physical parameters within the solar system and universe so exact that they cannot be random.  Indeed, the lack of a scientific explanation has allowed these facts to be hijacked as a defense of intelligent design.

Without perception, there is in effect no reality.  Nothing has existence unless you, I, or some living creature perceives it, and how it is perceived further influences that reality.  Even time itself is not exempted from biocentrism.  Our sense of the forward motion of time is really the result of an infinite number of decisions that only seem to be a smooth continuous path. At each moment we are at the edge of a paradox known as The Arrow, first described 2,500 years ago by the philosopher Zeno of Elea.  Starting logically with the premise that nothing can be in two places at once, he reasoned that an arrow is only in one place during any given instance of its flight.  But if it is in only one place, it must be at rest. The arrow must then be at rest at every moment of its flight.  Logically, motion is impossible.  But is motion impossible?  Or rather, is this analogy proof that the forward motion of time is not a feature of the external world but a projection of something within us?  Time is not an absolute reality but an aspect of our consciousness.

This paradox lies at the heart of one of the great revolutions of 20th
-century physics, a revolution that has yet to take hold of our understanding of the world and of the decisive role that consciousness plays in determining the nature of reality.  The uncertainty principle in quantum physics is more profound than its name suggests.  It means that we make choices at every moment in what we can determine about the world.  We cannot know with complete accuracy a quantum particle’s motion and its position at the same time—we have to choose one or the other.  Thus the consciousness of the observer is decisive in determining what a particle does at any given moment.

Einstein was frustrated by the threat of quantum uncertainty to the hypothesis he called spacetime, and spacetime turns out to be incompatible with the world discovered by quantum physics.  When Einstein showed that there is no universal now, it followed that observers could slice up reality into past, present, and, future, in different ways, all with equal reality.  But what, exactly, is being sliced up?

Space and time are not stuff that can be brought back to the laboratory in a marmalade jar for analysis.  In fact, space and time fall into the province of biology—of animal sense perception—not of physics.  They are properties of the mind, of the language by which we human beings and animals represent things to ourselves.  Physicists venture beyond the scope of their science—beyond the limits of material phenomena and law—when they try to assign physical, mathematical, or other qualities to space and time.

Return to the revelation that we are thinking animals and that the material world is the elusive substratum of our conscious activity continually defining and redefining the real.  We must become skeptical of the hard reality of our most cherished conceptions of space and time, and of the very notion of an external reality, in order to recognize that it is the activity of consciousness itself, born of our biological selves, which in some sense creates the world, once we understand all the synaptic connections in the brain. “The tools of neuroscience,” wrote philosopher and author David Chalmers (Scientific American, December 1995) “cannot provide a full account of conscious experience, although they have much to offer. ...Consciousness might be explained by a new kind of theory.”  Indeed, in a 1983 National Academy Report, the Research Briefing Panel on Cognitive Science and Artificial Intelligence stated that the questions to which it concerned itself “reflect a single underlying great scientific mystery, on par with understanding the evolution of the universe, the origin of life, or the nature of elementary particles.”

The mystery is plain.  Neuroscientists have developed theories that might help to explain how separate pieces of information are integrated in the brain and thus succeed in elucidating how different attributes of a single perceived object—such as the shape, color, and smell of a flower—are merged into a coherent whole.  These theories reflect some of the important work that is occurring in the fields of neuroscience and psychology, but they are theories of structure and function.  They tell us nothing about how the performance of these functions is accompanied by a conscious experience
; and yet the difficulty in understanding consciousness lies precisely here, in this gap in our understanding of how a subjective experience emerges from a physical process.  Even Steven Weinberg concedes that although consciousness may have a neural correlate, its existence does not seem to be derivable from physical laws.

Physicists believe that the theory of everything is hovering right around the corner, and yet consciousness is still largely a mystery, and physicists have no idea how to explain its existence from physical laws.  The questions physicists long to ask about nature are bound up with the problem of consciousness. Physics can furnish no answers for them.  “Let man,” declared Emerson, “then learn the revelation of all nature and all thought to his heart
; this, namely; that the Highest dwells with him; that the sources of nature are in his own mind.”

Space and time, not proteins and neurons, hold the answer to the problem of consciousness.  When we consider the nerve impulses entering the brain, we realize that they are not woven together automatically, any more than the information is inside a computer.  Our thoughts have an order, not of themselves, but because the mind generates the spatio
-temporal relationships involved in every experience.  We can never have any experience that does not conform to these relationships, for they are the modes of animal logic that mold sensations into objects.  It would be erroneous, therefore, to conceive of the mind as existing in space and time before this process, as existing in the circuitry of the brain before the understanding posits in it a spatio-temporal order.  The situation, as we have seen, is like playing a CD—the information leaps into three-dimensional sound, and in that way, and in that way only, does the music indeed exist.

We are living through a profound shift in worldview, from the belief that time and space are entities in the universe to one in which time and space belong to the living.  Think of all the recent book titles—The End of Science, The End of History, The End of Eternity, The End of Certainty, The End of Nature, and The End of Time.  Only for a moment, while we sort out the reality that time and space do not exist, will it feel like madness.
