Summary of Endless Universe

Endless Universe: Beyond the Big Bang by Paul J. Steinhardt and Neil Turok is a comprehensive and accessible examination of the theoretical framework that could explain the origin and evolution of the universe. The authors argue that the universe may not be limited to one big bang, but instead that it could exist as an endlessly cycling universe of its own creation. They then describe their Cyclic Universe Theory, which proposes that the universe goes through a series of big bangs and expansions over infinite time. This book explores how the cyclic universe fits into today’s cosmology, and how it can be tested, and examines the larger implications of such an idea.
