Nigel Calder’s landmark book has been acclaimed for making Albert Einstein’s theories of relativity accessible to the public. The universe that Einstein built is an astonishing skyscape of bent starlight, high-speed astronauts, black holes, stormy galaxies, and exploding spacetime. Today it seems more certain than ever that we live in the cosmos he described—yet often we still fail to understand it. Einstein’s Universe unlocks the secrets of an astounding vision of the world. How can a black hole keep you young? Why does a falling person feel no force of gravity? Answering these and many other questions, Einstein’s Universe makes plain the debt that humanity owes to the man who completely reshaped our ideas of energy, time, and motion.

"A valuable contribution to the de-mystification of relativity." —Nature

"Calder’s gift for simplifying the complex has rarely been better demonstrated." —San Francisco Examiner & Chronicle
