For this expanded edition, Professor Hawking prepared a new introduction to the book, wrote an entirely new chapter on wormholes and time travel, and updated the original text. This edition is enhanced throughout with more than 240 full-color illustrations, including satellite images, photographs made possible by spectacular technological advances such as the Hubble Space Telescope, and computer-generated images of three- and four-dimensional realities. A classic work that now brings to the reader the latest understanding of cosmology, The Illustrated Brief History of Time is the story of the ongoing search for the secrets at the heart of time and space. In The Universe in a Nutshell, Stephen Hawking takes us to the cutting edge of theoretical physics, where he seeks to uncover the grail of science --the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe --from supergravity to supersymmetry, from quantum theory to M theory, from holography to duality. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions and where the original cosmic seed from which our universe sprang was a tiny nut.
