Are there other dimensions beyond our own? Is time travel possible? Can
we change the past? Are there gateways to parallel universes? All of us
have pondered such questions, but there was a time when scientists
dismissed these notions as outlandish speculations. Not any more. Today,
they are the focus of the most intense scientific activity in recent
memory. In Hyperspace, Michio Kaku, author of the widely acclaimed
Beyond Einstein and a leading theoretical physicist, offers the first
book-length tour of the most exciting (and perhaps most bizarre) work in
modern physics, work which includes research on the tenth dimension,
time warps, black holes, and multiple universes. The theory of
hyperspace (or higher dimensional space) - and its newest wrinkle,
superstring theory - stand at the center of this revolution, with
adherents in every major research laboratory in the world, including
several Nobel laureates. Beginning where Hawking's Brief History of Time
left off, Kaku paints a vivid portrayal of the breakthroughs now rocking
the physics establishment. Why all the excitement? As the author points
out, for over half a century, scientists have puzzled over why the basic
forces of the cosmos - gravity, electromagnetism, and the strong and
weak nuclear forces - require markedly different mathematical
descriptions. But if we see these forces as vibrations in a higher
dimensional space, their field equations suddenly fit together like
pieces in a jigsaw puzzle, perfectly snug, in an elegant, astonishingly
simple form. This may thus be our leading candidate for the Theory of
Everything. If so, it would be the crowning achievement of 2,000 years
of scientific investigation into matter and itsforces. Already, the
theory has inspired several thousand research papers, and has been the
focus of over 200 international conferences. Many leading scientists
believe the theory will unlock the deepest secrets of creation and
answer some of the most intriguing questions of all
