The award-winning former editor of Science News shows that one of the most fascinating and controversial ideas in contemporary cosmology-the existence of multiple parallel universes-has a long and divisive history that continues to this day. We often consider the universe to encompass everything that exists, but some scientists have come to believe that the vast, expanding universe we inhabit may be just one of many. The totality of those parallel universes, still for some the stuff of science fiction, has come to be known as the multiverse. The concept of the multiverse, exotic as it may be, isn't actually new. In The Number of the Heavens, veteran science journalist Tom Siegfried traces the history of this controversial idea from antiquity to the present. Ancient Greek philosophers first raised the possibility of multiple universes, but Aristotle insisted on one and only one cosmos. Then in 1277 the bishop of Paris declared it heresy to teach that God could not create as many universes as he pleased, unleashing fervent philosophical debate about whether there might exist a "plurality of worlds." As the Middle Ages gave way to the Renaissance, the philosophical debates became more scientific. Rene Descartes declared "the number of the heavens" to be indefinitely large, and as notions of the known universe expanded from our solar system to our galaxy, the debate about its multiplicity was repeatedly recast. In the 1980s, new theories about the big bang reignited interest in the multiverse. Today the controversy continues, as cosmologists and physicists explore the possibility of many big bangs, extra dimensions of space, and a set of branching, parallel universes. This engrossing story offers deep lessons about the nature of science and the quest to understand the universe.
"An eager, ambitious book. A stimulating, accessible introduction to scientific theory."——Dallas Morning News "An enjoyably quick-paced interdisciplinary survey of the outer limits of scientific thought."——Kirkus Reviews "Siegfried weaves a provocative and convincing argument. . . . Recommended for an informed audience."——Library Journal "An excellent introduction to the myriad small worlds that can be teased out of our big one."——Publishers Weekly "A volume of remarkable sweep."——Booklist Now in paperback, The Bit and the Pendulum explores the radical idea at the center of the new physics of information: everything in the universe, from the molecules in our bodies to the heart of a black hole, is made up of bits of information.Award-winning author Tom Siegfried interviews top scientists–all using "bits" to solve the seemingly unsolvable–and provides a highly accessible introduction to a fundamentally new way of seeing the world. Lively, engaging, and topical, The Bit and the Pendulum shows how the computer and the "bit" are revealing secrets of the brain, the nature of matter, and the workings of the universe.
Funny, clear, deep, and right on target. Siegfried] lets us get a
handle on ideas that are essential for understanding the evolving
world.
