Quantum computers, quantum cryptography, and even quantum AI—a century after uncovering an unexpected physical world, researchers are putting this puzzling science to work in dazzling new ways.

In this exhilarating and mind-bending book, renowned scientist and author Paul Davies offers readers a glimpse of how quantum physics has led to a quantum technology revolution. Quantum 2.0 reveals how today’s brightest minds are harnessing exotic states of matter that have no counterpart in everyday life. Specifically, all eyes are on entanglement, called “spooky” by Einstein, that links the activities of separated particles even across vast distances.

By manipulating these weird properties of atoms, electrons, and photons, scientists are driving the burgeoning field of “quantum information science,” featuring new tools such as quantum computers, quantum cryptography, and the quantum internet. In turn, their efforts have attracted billions of dollars in investments and triggered a frantic quantum arms race between nations. At the same time, theorists are taking a closer look at quantum systems themselves, which possess properties that defy intuition and shred everyday notions of reality. Davies explains how researchers, including himself, are wrestling with quantum theory to make sense of this realm, where ghostly quantum particles produce tiny forces in nanotechnology, cause black holes to evaporate, and may even contribute to the universe’s accelerating expansion. A trusted guide, Davies takes readers from the basic concepts to today’s cutting-edge, inviting us all to see the wonderland of quantum physics and glimpse its stunning implications.

Combining the latest scientific advances with storytelling skills unmatched in the cosmos, an award-winning astrophysicist and popular writer leads us on a tour of some of the greatest mysteries of our universe.
 
In the constellation of Eridanus, there lurks a cosmic mystery: It’s as if something has taken a huge bite out of the universe. But what is the culprit? The hole in the universe is just one of many puzzles keeping cosmologists busy. Supermassive black holes, bubbles of nothingness gobbling up space, monster universes swallowing others—these and many other bizarre ideas are being pursued by scientists. Due to breathtaking progress in astronomy, the history of our universe is now better understood than the history of our own planet. But these advances have uncovered some startling riddles. In this electrifying new book, renowned cosmologist and author Paul Davies lucidly explains what we know about the cosmos and its enigmas, exploring the tantalizing—and sometimes terrifying—possibilities that lie before us.

As Davies guides us through the audacious research offering mind-bending solutions to these and other mysteries, he leads us up to the greatest outstanding conundrum of all: Why does the universe even exist in the first place? And how did a system of mindless, purposeless particles manage to bring forth conscious, thinking beings? Filled with wit and wonder, What’s Eating the Universe? is a dazzling tour of cosmic questions, sure to entertain, enchant, and inspire us all.
