This is truly a mind stretching, imagination-dilating book.

According to the theory of eternal inflation, there's a multiverse consisting of an exponentially expanding sea of high-energy "false vacuum." This sea continually gives rise to embedded, expanding, true-vacuum "bubble universes," each of which from the *inside* seems to have sprung from a Big Bang and to be spatially *infinite*.
Our own observable universe (OU) is a finite (albeit currently about 10^10 or 10^11 light-years in size) part of one bubble universe. Different regions of the bubble that are vastly larger than the OU will have different laws of physics. (This is relevant for the apparent "fine-tuning" of the physical constants [which the intelligent-design crowd is so eager to misinterpret] and the validity of some versions of the anthropic principle.)
Anything physically conceivable must occur an infinite number of times somewhere in our bubble (not to mention in all the other bubbles). E.g. an exact duplicate of Earth and you and me might exist as "close" as 10^(10^123) light-years away! (That's a number so big that writing it out in decimal would take more paper than could fit in the OU.)
If all that is not enough (and it *is* serious, mathematically rigorous science), there could also be more than one multiverse, and some bubbles could be spawned within other bubbles. Truly mind-bending.

Amazon.com Product Description (ISBN 0809095238, Hardcover)

Recent discoveries in cosmology have led to a bizarre new worldview that (to paraphrase Niels Bohr) may be crazy enough to be true. Just consider the litany of mind-boggling new ideas being bandied about lately: the acceleration of cosmic expansion, dark energy (on top of dark matter, yet!), primordial “ripples” in space-time, the quantum creation of the universe from nothing, eternal cosmic inflation, multiple universes . . .Sound crazy enough for you?
Fortunately, the new theoretical advances also lead to testable predictions, and we may soon witness the confirmation of some of these predictions by fresh astronomical findings. Alex Vilenkin’s own scientific work has been closely tied to the emergence of the new worldview, from the original ideas to the most recent developments. In Many Worlds in One, he gives an exciting, surprisingly entertaining firsthand account of the birth of the new cosmology, and its fascinating—and at times disturbing—implications.

(see all 2 descriptions)

A director of the Tufts Institute of Cosmology introduces and summarizes current theories pertaining to such ideas as dark matter, ripples in space-time, and multiple universes in a volume that offers insight into how new theoretical advances are enabling a new cosmological discipline.… (more)
