Now in paperback, Something Deeply Hidden attempts what no book for a popular audience has undertaken. Quantum mechanics underlies all of modern physics, but major gaps in the theory have been ignored since 1927. Science popularizers keep telling us how weird it is, how contradictory, how impossible it is to understand. Academics discourage students from working on the "dead end" of quantum foundations. Putting his professional reputation on the line, Carroll says that crisis can now come to an end. We just have to accept that there is more than one of us in the universe. There are many, many Sean Carrolls. Many of every one of us. Step-by-step in Carroll's uniquely lucid way, he sets out the major objections to this utterly mind blowing notion until his case is inescapably established. Carroll argues that our refusal to face up to the mysteries of quantum mechanics has blinded us, and that spacetime and gravity naturally emerge from a deeper reality called the wave function. We're on the threshold of a new way of understanding the cosmos.
