Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime

More about the book

INSTANT NEW YORK TIMES BESTSELLER and one of Publishers Weekly’s “Most Anticipated Books of the Fall,” this work by Sean Carroll, a renowned theoretical physicist, redefines 20th-century physics. It reveals how confronting the core puzzle of quantum mechanics reshapes our understanding of space and time. Carroll’s integration of quantum mechanics with Einstein’s theory of relativity presents a transformative perspective. He argues that physics has been in crisis since 1927, as significant gaps in quantum mechanics have been overlooked. While science communicators often highlight the strangeness of quantum mechanics, academics tend to steer students away from exploring its foundational issues. Carroll, risking his professional reputation, asserts that this crisis can be resolved by accepting the existence of multiple versions of ourselves in the universe. According to the Many Worlds Theory, every quantum event results in a world branching off, with countless copies of us created every second. Through a clear and methodical approach, Carroll addresses major objections to this groundbreaking idea, ultimately establishing his argument. This book offers a profound reorganization of our understanding of our place in the cosmos and what constitutes our existence.
