Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime

“Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime” is a book written by physicist and author Sean Carroll. In this book, Carroll delves into the fascinating and complex world of quantum mechanics and its implications for our understanding of reality, time, and the nature of the universe.

Carroll explores the concept of the many-worlds interpretation of quantum mechanics, which is a particular interpretation of quantum theory. According to this interpretation, the universe doesn’t choose a single outcome for a quantum event; instead, every possible outcome occurs, branching into multiple parallel worlds. In other words, for every quantum event with multiple possible outcomes, a new universe is created for each outcome, leading to a vast multiverse of parallel realities.

The book discusses the scientific underpinnings of this interpretation, its historical development, and its implications for our understanding of the fundamental nature of the universe. Carroll also addresses the idea of spacetime and how it might emerge from the quantum realm.

“Something Deeply Hidden” is not only a book about quantum physics but also an exploration of the philosophical and metaphysical implications of these ideas. It is written for a general audience interested in understanding the cutting-edge concepts in theoretical physics and the profound questions they raise about the nature of reality and the universe.
