The Fabric of Reality: The Science of Parallel Universes--and Its Implications

A penetrating exploration of the new physics, including time travel, quantum computers, and the multiverse from an award-winning physicist. For David Deutsch, a 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 based on four main strands: Quantum physics and its many-universes interpretation; The theory of evolution (Darwin/Dawkins); The theory of computation (quantum computation); The theory of knowledge (Karl Popper), explanation and understanding.
