From Publishers Weekly
Well-known physicist and author Kaku (Hyperspace) tells readers in this latest exploration of the far reaches of scientific speculation that another universe may be floating just a millimeter away on a "brane" (membrane) parallel to our own. We can't pop our heads in and have a look around because it exists in hyperspace, beyond our four dimensions. However, Kaku writes, scientists conjecture that branes—a creation of M theory, marketed as possibly the long-sought "theory of everything"—may eventually collide, annihilating each other. Such a collision may even have caused what we call the big bang. In his usual reader-friendly style, Kaku discusses the spooky objects conjured up from the equations of relativity and quantum physics: wormholes, black holes and the "white holes" on the other side; universes budding off from one another; and alternate quantum realities in which the 2004 elections turned out differently. As he delves into the past, present and possible future of this universe, Kaku will excite readers with his vision of realms that may exist just beyond the tip of our noses and, in what he admits is a highly speculative section, the possibilities our progeny may enjoy countless millennia from now; for instance, as this universe dies (in a "big freeze"), humans may be able to escape into other universes.

In the end, as our universe is dying, will civilization be able to move to another universe? Kaku, professor of theoretical physics at the City University of New York, thinks the possibility of such a transition appears in "the emerging theory of the multiverse--a world made up of multiple universes, of which ours is but one." Our universe is now expanding. "If this antigravity force continues, the universe will ultimately die in a big freeze." That is a law of physics. "But it is also a law of evolution that when the environment changes, life must either leave, adapt, or die." Moving to another universe is one possibility cited by Kaku. Another is that civilization could build a "time warp" and travel back into its own past, to an era before the big freeze. A third is that "an entire civilization may inject its seed through a dimensional gateway and reestablish itself, in its full glory." Kaku is good at explaining the cosmological ideas--among them string theory, inflation, wormholes, space and time warps, and higher dimensions--that underpin his argument.

Most of this book will be easily understandable for the average lay person. However, much of the book is spent on string theory. If you don't have at least some education in college level physics, some of this may be difficult to understand (not to mention a little dry). That said, Dr. Kaku does a better job than most in explaining in. All in all, this is an important book explaining some of the most cutting edge theories and concepts in modern physics. I highly recommend it for anyone interested in astronomy or astrophysics.
