Multiverse theories and debates in science

 Those of you who peruse Slashdot would have seen this post today:

"Scientific American is running a piece by science journalist John Horgan attacking pop physicist Brian Greene's latest offering, titled The Hidden Reality. He's not entirely alone; Not Even Wrong backs him up and reminds us of a growing list of multiverse propaganda. The journal Nature ran a short piece trying to remind everyone that Greene's book is more theory than fact, but apart from those three responses, the popular press seems to be gobbling up this tantalizing concept of a multiverse. NPR offers an excerpt while SFGate and The Wall Street Journal entertain us with interviews of the controversial Greene. The New York Times and Salon seem to think it's worthwhile, with Salon even calling it 'the science behind' the multiverse theory. The New York Times thought it worthwhile to give Greene an op-ed column. For better or for worse, Greene has certainly brought this great debate to the public's attention — similar to his exhibition of String Theory."

The Hidden Reality may be worth checking out.  Here's the overview from the book:

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 doppelgangers, 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 mathematics.  

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.

Now science want to prove what we already believe in, the mult-layered nature of reality.
