Michio Kaku, one of the leading scientific pioneers of this century, paints a vivid portrait of the groundbreaking theory of hyperspace (high dimensional space), and its newest wrinkle, superstring theory. If the basic forces of the universe are seen as vibrations in a higher dimensional space, their field equations suddenly fit together like pieces in a jigsaw puzzle, perfectly snug, in an elegant yet simple form that may be our leading candidate for the Theory of Everthing.
