Michio Kaku: Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps, and the 10th Dimension

How many dimensions do you live in? Three? Maybe that's all your commonsense sense perception perceives, but there is growing and compelling evidence to suggest that we actually live in a universe of ten real dimensions. Kaku has written an extraordinarily lucid and thought-provoking exploration of the theoretical and empirical bases of a ten-dimensional universe and even goes so far as to discuss possible practical implications--such as being able to escape the collapse of the universe. Yikes. Highly Recommended.

From Publishers Weekly

Since ingesting Einstein's relativity theory 50 years ago, physics fell down a quantum rabbit hole and, ever since, physicists' reports to the world of popular science have been curiouser and curiouser. This version, from the author of the graduate text Quantum Field Theory , is very curious as he delineates the "delicious contradictions" of the quantum revolution: that the new paradigms of subatomic matter require the existence of "hyperspace," an ultimate universe of many dimensions, to accomodate their mostly mathematical behaviors. Unified field theory as it is currently understood does not preclude any of the hypotheses that Kaku invites to this Mad Hatter's Theory Party: superstrings, parallel universes and, his centerpiece, time travel. Although occasionally facile, Kaku remains on solid theoretical ground up to the point of his untestable hypotheses, which lead to his more abstract arguments. In the past decade particle physics has lurched to astonishing contradictions and Kaku's adventurous, tantalizing book should not be penalized for promising more than present technology can test. His intellectual perceptions will thrill lay readers, SF fans and the physics-literate. Illustrations.

From Library Journal

With erudition and wisdom, Kaku (physics, CUNY) has written a fascinating overview of the major scientists, discoveries, and ideas involved in an ongoing quest for synthesizing quantum mechanics and relativity physics into a superstring theory of our entire universe (unifying gravity, electromagnetism, and the strong and weak nuclear forces). His clear and concise exposition in cosmology explores many topics, ranging from subatomic particles (e.g., quarks and leptons), exobiology, and black holes to wormholes, time travel, and other universes. Kaku stresses that modern physics still needs a more powerful topology mathematics in order to understand completely our expanding and evolving cosmos. Of value for both specialists and general readers, Hyperspace is an engaging and intriguing book. Highly recommended for all science collections in academic and public libraries.

From Kirkus Reviews

Kaku (Physics/CCNY) is the author (with Jennifer Trainer) of Beyond Einstein (1987) and of several popular volumes on advanced physics. He is also the host of a weekly radio program on modern science. Here, he offers a popular explanation of how the mathematics of higher dimensions underlies modern physical theories, notably the superstring hypothesis of how the universe is put together. The great problem confronting physics has been the building of a bridge between relativity and quantum theory: a single theory reconciling the two extremes of the very large and the very small. Relativity is proven beyond doubt on the scale of planets and galaxies; quantum theory applies to the microcosmic world of subatomic particles. Ever since Einstein, physicists have been trying, and failing, to combine the two into a GUT (Grand Unified Theory). Although it remains controversial among physicists and cosmologists, Kaku proffers superstring theory as the best approximation yet--but it requires acceptance of a counter-intuitive system in which our sensory world, hosting three dimensions of space and one of time, is only a small part of a universe containing ten dimensions (six of them undetectable by our limited senses). Higher dimensions, aka hyperspace, seem to some physicists the most consistent description of the universe we actually inhabit, and to others just one more futile attempt to unify relativity and quantum theory. Kaku admits the futility of visualizing a ten-dimensional universe with our three-dimensional mindset; in fact, he admits that the mathematics of superstring theory are so difficult that many of the key equations remain unsolved. But he effectively marshals examples from everyday experience and the labors of working scientists to illuminate current theories of how the universe really works (to the extent that anyone can understand it without working the equations), offering intelligent speculations on how time travel and faster-than-light travel might be possible. Kaku's explanations of the principles of superstring theory are lucid, lively, and full of entertaining glimpses of the researchers involved. A worthy successor to the popular physics texts of George Gamow, as thought-provoking as Stephen Hawking. -- Copyright ©1994, Kirkus Associates, LP. All rights reserved.

Book Description

The first book-length exploration of the most exciting development in modern physics, the theory of 10-dimensional space. The theory of hyperspace, which Michio Kaku pioneered, may be the leading candidate for the Theory of Everything that Einstein spent the remaining years of his life searching for.
