As you read these words, copies of you are being created.
Sean Carroll, theoretical physicist and one of this world’s most celebrated writers on science, rewrites the history of 20th century physics. Already hailed as a masterpiece, Something Deeply Hidden shows for the first time that facing up to the essential puzzle of quantum mechanics utterly transforms how we think about space and time. His reconciling of quantum mechanics with Einstein’s theory of relativity changes, well, everything.
Most physicists haven’t even recognized the uncomfortable truth: physics has been in crisis since 1927. Quantum mechanics has always had obvious gaps—which have come to be simply ignored. Science popularizers keep telling us how weird it is, 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 with this audacious yet entirely reasonable book, Carroll says that the 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.
Copies of you are generated thousands of times per second. 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. Step-by-step in Carroll's uniquely lucid way, he tackles the major objections to this otherworldly revelation until his case is inescapably established.
Rarely does a book so fully reorganize how we think about our place in the universe. We are on the threshold of a new understanding—of where we are in the cosmos, and what we are made of.
PUBLISHERS WEEKLY
Theoretical physicist Carroll (The Big Picture) explores holes in the foundation of modern physics in this challenging, provocative book. Quantum mechanics is, according to Carroll, "the deepest, most comprehensive view of reality we know of." But while it answers questions about how the universe works at the microscopic level, quantum theory still, nearly 100 years after its introduction, has unresolved issues. Albert Einstein disdained quantum mechanics as "spooky" and said it would never be complete, and so far, Carroll says, he's been right. Carroll presents his argument with words rather than math, striving to make even the most abstract ideas clear. At the heart of his discussion are equations called "wave functions" that describe the real world. The problem is that wave functions have many possible solutions and each describes a branch, or another reality, in spacetime. Carroll gives a sense of both the frustration and the wonder that the many-worlds theory inspires, and what it implies about free will and human consciousness. Moving smoothly through different topics and from objects as small as particles to those as enormous as black holes, Carroll's exploration of quantum theory introduces readers to some of the most groundbreaking ideas in physics today. This review has been updated with more precise language regarding wave functions.
