Emergent Multiverse

The Emergent Multiverse presents a striking new account of the many worlds approach to quantum theory. The point of science it is generally accepted is to tell us how the world works and what it is like. But quantum theory seems to fail to do this: taken literally as a theory of the world it seems to make crazy claims: particles are in two places at once; cats are alive and dead at the same time. So physicists and philosophers have often been led either to give up on the idea that quantum theory describes reality or to modify or augment the theory.
