Parallel Worlds: The Science of Alternative Universes and our Future in the Cosmos

Is our universe dying? Could there be other universes?In Parallel Worlds, world-renowned physicist and bestselling author Michio Kaku--an author who "has a knack for bringing the most ethereal ideas down to earth" (Wall Street Journal)--takes readers on a fascinating tour of cosmology, M-theory, and its implications for the fate of the universe.In his first book of physics since Hyperspace, Michio Kaku begins by describing the extraordinary advances that have transformed cosmology over the last century, and particularly over the last decade, forcing scientists around the world to rethink our understanding of the birth of the universe, and its ultimate fate. In Dr. Kaku's eyes, we are living in a golden age of physics, as new discoveries from the WMAP and COBE satellites and the Hubble space telescope have given us unprecedented pictures of our universe in its infancy.As astronomers wade through the avalanche of data from the WMAP satellite, a new cosmological picture is emerging. So far, the leading theory about the birth of the universe is the "inflationary universe theory," a major refinement on the big bang theory. In this theory, our universe may be but one in a multiverse, floating like a bubble in an infinite sea of bubble universes, with new universes being created all the time. A parallel universe may well hover a mere millimeter from our own.
