"The Theory of Everything" is a unique opportunity to explore the cosmos with the greatest mind since Einstein. Based on a series of lectures given at Cambridge University, Professor Hawking''s work introduced "the history of ideas about the universe" as well as today''s most important scientific theories about time, space, and the cosmos in a clear, easy-to-understand way.

Join George and Annie as they explore the galaxy in this cosmic adventure series from acclaimed scientist Stephen Hawking and his daughter Lucy Hawking. This four-book collection includes: George’s Secret Key to the Universe George’s Cosmic Treasure Hunt George and the Big Bang George and the Unbreakable Code

Einstein''s General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a ''black hole'' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein''s field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

"George is trapped miles away from home, desperately missing his family and his best friend, Annie. All he wants is to return to Earth, but when he eventually touches down something is terribly wrong. His home is a barren wasteland and strange robots roam the streets. With the help of an unexpected new friend, George must figure what or who is behind this terrible transformation before it''s too late."--Back cover.
