In a video that recently aired on “Through the Wormhole” narrated by Morgan Freeman on the TV channel Science, Dr. Hameroff claims, "I believe that consciousness, or its immediate precursor proto-consciousness, has been in the universe all along, perhaps from the Big Bang."
Understanding where consciousness comes from could solve mysteries such as what happens to the "soul" during near-death experiences, or when a person dies.
Dr. Hameroff goes on to share hypothetical scenarios derived from the Orch-OR (orchestrated objective reduction) theory of consciousness that he and Roger Penrose, mathematician and physicist, proposed in 1996. According to the theory, consciousness is derived from microtubules within brain cells (neurons) which are sites of quantum processing.
But what exactly is consciousness, where does it come from and can it be scientifically proven? Dr. Stuart Hameroff, MD, is Professor Emeritus at the Departments of Anesthesiology and Psychology and the Director of the Center of Consciousness Studies at the University of Arizona and much of his research over the past few decades has been in the field of quantum mechanics, dedicated to studying consciousness.
According to Dr. Hameroff, in a near-death experience, when the heart stops beating, the blood stops flowing, and the microtubules lose their quantum state, the quantum information in the microtubules isn't destroyed. It's distributed to the universe at large, and if the patient is revived, the quantum information can go back to the microtubules. In this event, the patient says they had something like a near-death experience, i.e. they saw white light or a tunnel or floated out of their body. In the event that the patient is not revived, "it's possible that the quantum information can can exist outside the body, perhaps indefinitely, as a soul," he said.
The Orch-OR theory of consciousness remains controversial in the scientific community. Many scientists and physicists have challenged it, including MIT physicist Max Tegmark, who wrote a paper in 2000 that was widely cited.
Still, Dr. Hameroff believes that "nobody has landed a serious blow to the theory. It's very viable."

Charles Darwin (1809-1882)
"The impossibility of conceiving that this grand and wondrous universe, with our conscious selves, arose through chance, seems to me the chief argument for the existence of God." <strong>Clarification</strong>: <em>The full quote, from <a href="http://www.darwinproject.ac.uk/entry-8837" target="_hplink">one of Darwin's letters</a>, carries a different sentiment. A young admirer <a href="http://www.ncbi.nlm.nih.gov/pubmed/16949157" target="_hplink">asked Darwin about his religious views</a> (the original inquiry is lost), and the great naturalist answered: "It is impossible to answer your question briefly; and I am not sure that I could do so, even if I wrote at some length. But I may say that the impossibility of conceiving that this grand and wondrous universe, with our conscious selves, arose through chance, seems to me the chief argument for the existence of God; but whether this is an argument of real value, I have never been able to decide."</em>
Neil deGrasse Tyson (1958-
"So you're made of detritus [from exploded stars]. Get over it. Or better yet, celebrate it. After all, what nobler thought can one cherish than that the universe lives within us all?" --American astrophysicist and science commentator
Stephen Hawking (1942-)
"What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary." --English physicist and cosmologist
Carl Sagan (1934-1996)
"Science is not only compatible with spirituality; it is a profound source of spirituality. When we recognize our place in an immensity of light-years and in the passage of ages, when we grasp the intricacy, beauty, and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual...The notion that science and spirituality are somehow mutually exclusive does a disservice to both." --American astrophysicist
Francis Collins (1950-)
"Science is...a powerful way, indeed - to study the natural world. Science is not particularly effective...in making commentary about the supernatural world. Both worlds, for me, are quite real and quite important. They are investigated in different ways. They coexist. They illuminate each other." --American physician-geneticist and director of the National Human Genome Research Institute
Isaac Asimov (1920-1992)
"Emotionally, I am an atheist. I don't have the evidence to prove that God doesn't exist, but I so strongly suspect he doesn't that I don't want to waste my time" --American biochemist and science fiction writer
Albert Einstein (1879-1955)
<strong>Clarification</strong>: <em>While the <a href="http://www.nytimes.com/2008/05/17/science/17einsteinw.html" target="_hplink">New York Times noted</a> that "Einstein consistently characterized the idea of a personal God who answers prayers as naive, and life after death as wishful thinking," he also "described himself as an 'agnostic' and 'not an atheist.'" One ambiguous quote, from <a href="http://books.google.com/books?id=58HQXMp1ESwC&pg=PA92&lpg=PA92&dq=einstein+phyllis+wright&source=bl&ots=zn6BlmXlY4&sig=DxDgqkMMwMaJ9pgUVmgwih4WbQE&hl=en&sa=X&ei=2NY6T6euHIbr0gHC4PivCw&ved=0CCwQ6AEwAjgK#v=onepage&q=einstein phyllis wright&f=false" target="_hplink">Einstein's response to a letter from a sixth-grade student named Phyllis Wright</a>, reads "Everyone who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the universe - a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble. In this way the pursuit of science leads to a religious feeling of a special sort, which is indeed quite different from the religiosity of someone more naive."</em> --German physicist, created theory of general relativity.

"It was not by accident that the greatest thinkers of all ages were deeply religious souls." --German physicist, noted for work on quantum theory
Erwin Schroedinger (1887-1961)
"I am very astonished that the scientific picture of the real world around me is very deficient. It gives a lot of factual information, puts all our experiences in a magnificently consistent order, but is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, god and eternity." --Austrian physicist, awarded Nobel prize in 1933
Rosalind Franklin (1920-1958)
"In my view, all that is necessary for faith is the belief that by doing our best we shall come nearer to success and that success in our aims (the improvement of the lot of mankind, present and future) is worth attaining...I maintain that faith in this world is perfectly possible without faith in another world." --British biophysicist renowned for her work on X-ray diffraction.
William H. Bragg (1862-1942)
"From religion comes a man's purpose; from science, his power to achieve it. Sometimes people ask if religion and science are not opposed to one another. They are: in the sense that the thumb and fingers of my hands are opposed to one another. It is an opposition by means of which anything can be grasped." --British physicist, chemist, and mathematician. Awarded Nobel Prize in 1915
Richard Feynman (1918-1988)
"God was invented to explain mystery. God is always invented to explain those things that you do not understand." --American physicist, awarded Nobel Prize in 1965
Wernher Von Braun (1912-1977)
"I find it as difficult to understand a scientist who does not acknowledge the presence of a superior rationality behind the existence of the universe as it is to comprehend a theologian who would deny the advances of science." --German-American rocket scientist
Richard Dawkins (1941-)
"The more you understand the significance of evolution, the more you are pushed away from the agnostic position and towards atheism. Complex, statistically improbable things are by their nature more difficult to explain than simple, statistically probable things." --British evolutionary biologist
Nevill Mott (1905-1996)
"Science can have a purifying effect on religion, freeing it from beliefs of a pre-scientific age and helping us to a truer conception of God. At the same time, I am far from believing that science will ever give us the answers to all our questions." --English physicist, awarded Nobel Prize in 1977
Fred Hoyle (1915-2001)
"A commonsense interpretation of the facts suggests that a superintellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question." --English mathematician and astronomer.
Sir Arthur C. Clarke (1917-2008)
"Science can destroy religion by ignoring it as well as by disproving its tenets. No one ever demonstrated, so far as I am aware, the nonexistence of Zeus or Thor - but they have few followers now" --British science fiction author and inventor
Walter Kohn (1923-)
"I am very much a scientist, and so I naturally have thought about religion also through the eyes of a scientist. When I do that, I see religion not denominationally, but in a more, let us say, deistic sense. I have been influence in my thinking by the writing of Einstein who has made remarks to the effect that when he contemplated the world he sensed an underlying Force much greater than any human force. I feel very much the same. There is a sense of awe, a sense of reverence, and a sense of great mystery." --American theoretical physicist, awarded Nobel Prize in 1998
Sam Harris (1967-)
"Atheism is not a philosophy; it is not even a view of the world; it is simply a refusal to deny the obvious." --American neuroscientist
Victor J. Stenger (1935-)
"With pantheism...the deity is associated with the order of nature or the universe itself...when modern scientists such as Einstein and Stephen Hawking mention 'God' in their writing, this is what they seem to mean: that God is Nature." --American physicist
