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.
