A penetrating exploration of the new physics, including time travel, quantum computers, and the multiverse – as referenced in the film “Avengers: Endgame”For David Deutsch, a young physicist of unusual originality, quantum theory contains our most fundamental knowledge of the physical world. Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book. The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

[The book] is full of refreshingly oblique, provocative insights. -- NY Times Book Review

This book contains more than enough in the way of new, fascinating, and in many cases stupefying insights into the underlying realities and meaning of our existence to inspire the best of science fiction for the next fifty years Outlines the quantum physics theory of multiple parallel universes, and describes how this theory, along with theories of evolution, computation, and knowledge, explain much of reality "A leading scientist interweaves evolution, theoretical physics, and computer science to offer a new understanding of reality"--Cover
