Publisher's Synopsis
Once the domain of the science fiction writer or the occultist, Hyperspace has recently been shown to be the only kind of space in which the laws of modern physics can be satisfactorily explained. Amazingly enough, many of the phenomena whose explanations have stymied 20th century physicists and cosmologists can now be perfectly clarified by using the ten dimensions of Hyperspace. Most importantly, Einstein's unfulfilled dream, the work on which he spent the last several decades of his life in vain - the unification of all the forces of nature - now sits waiting on the ten-dimensional doorstep of modern theoretical physicists.

Michio Kaku - theoretical high-energy physicist, author, radio talkshow host, and nuclear disarmament activist - is one of the pioneers in the field of String Theory, which states that the basic constituents of our universe are not quarks or protons or electrons, but much smaller entities called "strings" or "superstrings", which vibrate - like violin strings - in 10 dimensional Hyperspace, and whose vibrations in different resonances are manifested in the elementary particles.

"Ever since Einstein tried and failed to find a unified field theory relating gravity to the other forces of nature, physicists have vainly sought a method of describing the gravitational force in terms of quantum mechanics, perhaps even finding the hypothetical quantum particle thought to transmit this force - the graviton. A 'quantized' theory of gravity would allow theorists to fit gravity into its proper place in the natural order of things.

Mr. Kaku believes that the mathematical theory of 'superstrings' may already have accomplished this, by hypothesizing the existence of hyperspace. In brief, this means thinking of reality in terms of 10 dimensions, rather than in terms of the three dimensions of space that ordinary mortals can perceive, plus the one dimension of time. (The coordinate of each of the 10 dimensions must be perpendicular to the coordinates of all the others; this is impossible for a sane person to visualize, and even harder to imagine than the sound of one hand clapping.)

THE author introduces the reader rather painlessly to the geometry of higher dimensions. And without using equations, he offers a comprehensible explanation of a mathematical device called a metric tensor - a construction that plays a key role in discussions of hyperspace.

Mr. Kaku even gives an explanation of what may have happened to the six dimensions that we cannot perceive. If superstring theory is right, he suggests, the 10-dimensional infant universe may have split into two parts an instant after it came into being: one part became embedded in the familiar three dimensions of space and one of time, and the other part was retracted from view, so that the six remaining dimensions became hidden in string-like entities of almost infinitesimal size.

Mr. Kaku admits that theories based on hyperspace may strike some people as closer to religion than science. 'Because the hyperspace theory has opened up new, profound links between physics and abstract mathematics,' he writes, 'some people have accused scientists of creating a new theology based on mathematics.'

Hard-nosed physicists who dislike the cosmic philosophizing that sometimes springs from the paradoxes of quantum mechanics are certain to dislike parts of Mr. Kaku's book. Many physicists believe that quantum mechanics is a powerful and practical tool of technology, engineering, chemistry and physics, and think it is a mistake to agonize philosophically over its weird contradictions (for example, the way that electrons can 'tunnel' via probability waves, right through impenetrable objects - a phenomenon on which the ubiquitous transistor is based).

With superstring theory, the line between science and mysticism becomes distressingly blurred, and many scientists are uncomfortable about this. They acknowledge that although the equations underlying many of the new speculations are self-consistent and logical, they lack persuasive power because they cannot be tested in the real world. Scientists generally share the belief of the philosopher-physicist Ernst Mach that no statement is admissible in natural science unless it is empirically verifiable."      ~The New York Times
