The million-copy bestseller now illustrated with over 200 full-colour images, illuminating the fascinating science of our universe like never before.

Was there a beginning of time? Could time run backwards? Is the universe infinite or does it have boundaries? This book examines these questions. It begins by reviewing the great theories of the cosmos from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the Big Bang to black holes.
