author of The Elegant Universe and The Fabric of the Cosmos comes his most expansive and accessible book to date—a book that takes on the grandest question: Is ours the only universe? There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space: a multiverse in which you have an infinite number of doppelgängers, each reading this sentence in a distant universe; a multiverse comprising a vast ocean of bubble universes, of which ours is but one; a multiverse that endlessly cycles through time, or one that might be hovering millimeters away yet remains invisible; another in which every possibility allowed by quantum physics is brought to life. Or, perhaps strangest of all, a multiverse made purely of math. Greene, one of our foremost physicists and science writers, takes us on a captivating exploration of these parallel worlds and reveals how much of reality’s true nature may be deeply hidden within them.
This paper touches on a lot of the aspects in that book. With it and some undergrad math one can appreciate the brilliance of the paper.

I recently watched his conversation with Sam Harris and was intrigued by a point Brian made, albeit about quantum mechanics and the 'many worlds' theory.
Brian claims that he doesn't think the many worlds theory holds water because it makes an assumption about what happens before some object is measured (A) and after that same object is measured (A'): while many worlds claims that all possibilities are indeed realized, Brian claims that we just don't know for sure what happens between events (A) and (A'); he claims that a unified theory would explain what happens between those events.
In any case, that's just me rambling about it. Thanks for the post :)
Well, it turns out that the early universe went through a phase of incredible, extraordinary expansion called inflation. The inflation was boosted by something called an inflaton field, and due to quantum properties the inflaton field could spontaneously destabilize and spawn a bubble universe, each of which with a different Calabi-Yau manifold. It's possible that we are inside such a bubble universe, and outside of us the inflaton field is continuing to expand and producing more bubble universes. If this is the case, then it's not much of a surprise why our universe has the properties it does. Out of the 10^500 possibilities, a bubble universe spawned with the right Calabi-Yau manifold for life, and (unsurprisingly) we find ourselves living in that universe. This is the landscape multiverse theory. (I originally read about this theory in Brian Greene's excellent book The Hidden Reality, which describes many other multiverse theories too.)
Now, something important to note is that all this is still highly conjectural. String theory has many pleasing theoretical properties, but about zero physical evidence to support it. What then is the difference between string theory and deism? The difference is that for string theory (and more generally other multiverse theories) we actually have physical and mathematical theories that describe them. Deism doesn't. For string theory, we have papers, conferences, books, equations, and physicists and mathematicians who study this problem. We have something to work with. What do we have for deism? Well, pretty much nothing. No data, no theories, no anything. Deism is a fall-back theory when nothing else works out, and it has no theoretical roots and makes no predictions. This may change in the future, but as of now, deism is a scientific dead end. Of course, I don't know if string theory or another multiverse theory will pan out (indeed, the failure of the LHC to detect supersymmetry is raising some eyebrows), or even if deism actually turns out to be correct. However, on a scientific basis, string theory has more going for it now.
