Ever since Einstein’s general theory of relativity burst upon the world in 1915, some of the most brilliant minds of our century have sought to decipher its mysteries. Some of them—like black holes and time machines—are so unthinkable that Einstein himself rejected them.

The renowned physicist Kip S. Thorne has been in the thick of the quest. Now in this compelling account he describes these phenomena and explains what they tell us about the universe.

“Among the best of [its] genre to appear in recent years.”

—Malcolm W. Browne, front page review,

New York Times Book Review

“Readers seeking to go beyond today’s headlines will not find a higher authority (or a better storyteller) to discuss the cosmos’s most bizarre features.... Masterful and intriguing.”

—Marcia Bartusiak, Washington Post

“Superb. It is what many other books about the subject ought to have been and were not.... I think the book itself will be a strong force.”

—Carl Sagan

Black Holes & Time Warps reveals the scientific enterprise as very few books do; it richly overnows with history, modern physics, the excitement of discovery, and rare, flrsthand insightsof scientific styles and temperaments.”

—Alan Lightman

K IP S. T HORNE is the Feynman Professor of Theoretical Physics at the California Institute of Technology and the author of three other books, including (with John Wheeler and Charles Misner) Gravitation. He is the 1994 recipient of the American Institute of Physics Science Writing Award.
