PARALLEL WORLDS: A Journey through Creation, Higher Dimensions, and the Future of the Cosmos

Michio Kaku, . . Doubleday, $27.50 (448pp) ISBN 978-0-385-50986-2

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.
