I have come to the conviction that if you cannot translate your thoughts into uneducated language, then your thoughts were confused. Power to translate is the test of having really understood one’s own meaning.
Seeing as I had just finished reading the Michio Kaku booked (blogged about a bit in previous posts) I thought I'd use some of the themes that were fresh in my mind.
So anyway, let me know if I was successful or not in my "translation".
God or the Multi-verse? – Cosmology’s Big Question
Michio Kaku, an American quantum physicist, in his recent book Parallel Worlds, describes in layman’s terms what has become one of the most significant divergences of thought in the world of cosmology – the field of physics which deals with the origin of the universe and the ultimate nature of reality. On one side you have a growing community of string theorists who are embracing the ideas of M-theory, an idea that says there are an infinite number of universes in existence parallel to ours. On the other side of the debate are the proponents of the consciousness-causes-collapse theory, which maintains that by examining the evidence of quantum theory, one must conclude that the universe we live in is made possible by the existence of a universal consciousness, that observes reality and brings it into being. One sounds wilder than the most outrageous science fiction. The other sounds more like theology. However, both are dealt with in all seriousness as the only two real options for answering the questions raised by the experimental evidence of quantum physics.
The two opposing theories have arisen as a result of the scientific research of the 20th century, beginning essentially with the theoretical advancements of Einstein. Both theories set out to solve the problems of the wave-function. Quantum physicists have found the somewhat shocking and counter-intuitive truth that objects seem to require an observer in order to become what they are. Before observation, objects on the quantum level exist as waves rather than a concrete object. However, when the quantum object is observed or measured in an experiment, the wave-function “collapses” to become a definite, concrete object. This suggests that without interaction with consciousness, objects are nothing more than a bunch of waves. Some scientists, Einstein among them, found this conclusion impossible to accept. He was known to ask his guests, “Does the moon exist because a mouse looks at it?” Einstein believed that the answer had to be “no”, and expected that developments is physics would bear this out. But years of scientific advancement confirmed rather than refuted this odd hypothesis.
Both the multi-verse theory and the consciousness-causes-collapse theory set out to solve the dilemma raised by the mysteries of the wave-function. M-theorists however, reject the notion of a need for a conscious observer. They posit that instead of an observer collapsing a quantum event into one concrete state, the wave-function never collapses. Rather, all possible outcomes of a quantum event do occur – by splitting off into new and parallel universes. This means that any universe that can exist, does – though in a parallel universe inaccessible from ours. As MIT physicist Alan Guth puts it, "There is a universe where Elvis is still alive, and Al Gore is President."
On the other side of the debate are those who suppose that a more likely explanation is that there is a universal “observer” that collapses all wave functions into the one state that we call our universe. Proponents of this theory think that reality requires an external observer. But if I am bringing my cat into reality by observing it, doesn’t that require someone else to observe me, to collapse my waveform as well? Ultimately this line of reasoning suggests a greater consciousness that observes the entire universe, collapsing all waveforms, and bringing about all reality. Among this theory’s adherents were scientists like Nobel Laureate and peer of Einstein, Eugene Wigner, who expressed interest in the Vedanta concept of universal consciousness found in Hinduism. Another is Stanford physicist Andrei Linde, who commented in the June 2002 edition of Discover Magazine, “The moment you say that the universe exists without any observers, I cannot make any sense out of that. I cannot imagine a consistent theory of everything that ignores consciousness.”
While both M-theory and Consciousness-Causes-Collapse attempt to answer the biggest questions of the quantum theory, they haven’t been greeted with equal acceptance. The tendency within the scientific community is to look for answers that don’t rely on an inexplicable God-type resolution. This has resulted in M-theory’s rise to prominence as the current majority view. The problem remains, however, that the deepest questions of a cosmological nature are so theoretical that they lie beyond the realm of testability. For the time being, holding one view over the other will continue to be primarily an educated guess based on one’s own hunches, biases, and life experience.
