To find out what physicists have found out about God, read about mathematical physicist Prof. Frank Tipler's Omega Point Theory (of which Theory first appeared in book-form in The Anthropic Cosmological Principle [1986] co-written by leading astrophysicist John D. Barrow along with Tipler, and of which said book received almost universally fawning praise by the science media) in the short Wired article:

"From 2100 to the End of Time" by Frank J. Tipler:

http://math.tulane.edu/~tipler/wired.html

(Note: many of the numbers given in the above article are exponents which are not properly represented, e.g., such as showing 10^123 bytes as "10123 bytes," etc.)

The above article is by far the best introduction to the Omega Point Theory, also it is very short.

For more on the technical reasons why the known laws of physics require that the universe end in the Omega Point, see:

"The Ultimate Future of the Universe, Black Hole Event Horizons, Holography, and the Value of the Cosmological Constant" by Frank Tipler:

They have this article in PDF form under "Other formats." It is also only 2 pages long.

If you would like to watch a news report done on Tipler's Omega Point Theory, see:

"Proving God exists" by Chris Marrou
Eyewitness News KENS 5 San Antonio:

http://www.mysa.com/mysanantonio/kens5/series/517god.shtml

They have the full news report as well as four supplementary clips which are more in-depth. I highly recomend watching them as they are quite interesting.

Frank Tipler has also written a more detailed overview of the Omega Point Theory in The Critical Rationalist article "There Are No Limits To The Open Society," at:

http://www.eeng.dcu.ie/~tkpw/tcr/volume-03/number-02/v03n02.html

From the above article, be sure to read the "Technical Appendix: Why the Acceptance of the Known Laws of Physics Requires Acceptance of the Omega Point Theory."

The leading quantum physicist in the world, Dr. David Deutsch (winner of the Institute of Physics Paul Dirac Medal and Prize for his invention of the quantum computer), defends Frank Tipler's Omega Point Theory in Chapter 14 "The Ends of the Universe" in his excellent book The Fabric of Reality, of which chapter is available on-line with Frank Tipler's replies to it, here (which I most highly recomend that you read):

Here are some more on-line resources to learn about the Omega Point (i.e., the physicists' technical term for God):

NEW!: Be sure and check out the below excellent interview of Prof. Frank Tipler by Omni magazine entitled "A Physicist Proposes a Theory of Eternal Life that Yields God":

NEW!: You also won't want to miss Prof. Tipler's very informative reply to Martin Gardner's fideistic objection to the Omega Point Theory contained in Gardner's review of Tipler and Barrow's The Anthropic Cosmological Principle, both appearing in The New York Review of Books (be sure to take note of Mr. Gardner's two-word reply to Tipler):

Some have claimed that the recent supernovae data suggesting that the universe's expansion seems to be speeding up shows that the universe is open, as opposed to closed, which would obviate the Omega Point (since it requires that the universe be closed). But as physicists Michael Turner and Lawrence Krauss have demonstrated in the below paper, the supernovae data do not show this:

Read the below four-part USA Today series by Sam Meddis on Tipler's Omega Point Theory:

In praise of The Anthropic Cosmological Principle:

"... scholarly, philosophically sophisticated ... an engaging book, practically a universal education in the history of modern science and the history of the Universe. This book will be much quoted, much debated, and much praised. It deserves a place on the shelf of any serious scholar of science."
--Nature (3/27/86)

"... [an] impressive work on the philosophical issues of modern cosmology. ...The Anthropic Cosmological Principle is a comprehensive work that does justice to a fascinating subject."
--American Scientist (1/87)

"... written with great eloquence and zest ... a piece of natural philosophy in the old-fashioned sense ... only readers who are such impressive polymaths as the authors will really and fully appreciate the whole lot ... but ... I believe that any reader, whatever his background, is going to find parts of this book fascinating provided that the reader has ever wondered about the world and why we come to be in it."
--Martin Rees, FRS, former Plumian Professor of Astronomy at Cambridge University, now Royal Society Professor of Astronomy at Cambridge and Astronomer Royal, on the BBC program SCIENCE NOW (4/7/86)

"... this is a remarkable book. Nobody truly interested in philosophical aspects of cosmology can dispense with reading it. ... this book marks a new step along our way of addressing questions to the Universe."
--Classical and Quantum Gravity (3,727 [1986])

"... a work that should be ... in the hands of anyone who would see the state of late 20th century cosmology and where it is heading. ... Barrow and Tipler have made a 'classic' contribution to cosmology both in terms of their creative thinking and in their elaboration of the scope of the field."
--Journal of the American Scientific Affiliation (12/86)

"Is the Universe made for mankind? ... [Barrow and Tipler's] discussion is on as heroic a scale as the idea itself. ... [this reviewer] found this book extremely stimulating and interesting. ... it will be as widely read as it deserves to be."
--New Scientist (5/1/86)

In praise of The Fabric of Reality:

"David Deutsch is a deeply knowledgable professional physicist who has no truck with mystical false analogies . . . [he] has become the most eloquent spokesman of the Many Universes interpretation of quantum behavior, and [The Fabric of Reality] makes this theme coherent with some well-thought-out views of epistemology, of biological evolution, and of the theory of computation."
--Prof. Richard Dawkins, Oxford University, author of The Selfish Gene

"David Deutsch is one of Britain's most original thinkers. In this major work he confronts the deepest questions of existence head-on, challenging traditional notions of reality with a new world view that interweaves physics, computing and philosophy. I haven't been so inspired since reading Douglas Hofstadter's Gödel, Escher, Bach."
--Prof. Paul Davies, University of Adelaide, author of About Time: Einstein's Unfinished Revolution

"Deutsch is someone to be taken seriously ... he has made significant original contributions to the theory of quantum computing, and shows a broad command of an amazing range of material. He also writes clearly and forcefully. Moreover, his attempt at metaphysics in this book is based on sharp insights from physics and other branches of intellectual endeavour. Whereas most scientists, I think, find that much contemporary philosophy is quite alien and remote from their concerns, this book is different."
--Prof. Frank Wilczek, Physics World, June 1997

"Deutsch writes with great clarity, and his unifying philosophy is expressed persuasively and with a great deal of good sense."
--Prof. Sir Michael Berry, FRS, Physics, University of Bristol

"This is the finest popular work that I've read so far. ... I am bowled over by the incredible clarity, the carefully crafted sentences, the brilliant arguments, the way in which objections ... are dealt with as soon as they arise in the reader's mind ..."
--Dr. Enrico Rodrigo, Physics, University of Arizona

"The Fabric of Reality is a fascinating, highly readable, and wonderfully well-informed book about the world we live in. It will challenge and intrigue the philosopher of science and the intelligent layman alike. Deutsch, a physicist at Oxford, ranges over the fundamentals of contemporary physical science with a master's touch, illuminating, intriguing, and even inspiring as he goes. It is remarkable how well he is able to communicate what is often pretty arcane stuff to readers with little background knowledge or mathematical expertise. His book is a model of how these things ought to be done, as well as being probably the very best book of its type today."
--Prof. Jan Narveson, Philosophy, University of Waterloo, Canada
