Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime

Something Deeply Hidden begins with the news that physics is in a crisis. 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.



The Many Worlds theory of quantum behavior says that every time there is a quantum event, a world splits off with everything in it the same, except in that other world the quantum event didn’t happen. As you read this, you are splitting into multiple copies of yourself thousands of times per second. 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.
