Caltech physicist and New York Times bestselling author Sean Carroll shows that there are
multiple copies of you. And everyone else. Really. 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. The holy grail of
modern physics is reconciling quantum mechanics with Einstein's general relativity-his theory
of curved spacetime. 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. No book for a popular audience has attempted to make this radical
argument. We're on the threshold of a new way of understanding the cosmos.
