From the world-renowned physicist and best-selling author of The Elegant Universe comes this captivating exploration of deep time and humanity's search for purpose.Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in narrative, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality—from quantum mechanics to consciousness to black holes—Greene provides us with a clearer sense of how we came to be, a...

Amazon.com ReviewThere is an ill-concealed skeleton in the closet of physics: "As they are currently formulated, general relativity and quantum mechanics cannot both be right." Each is exceedingly accurate in its field: general relativity explains the behavior of the universe at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, believes that the two pillars of physics can be reconciled in superstring theory, a theory of everything.Superstring theory has been called "a part of 21st-century physics that fell by chance into the 20th century." In other words, it isn't all worked out yet. Despite the uncertainties--"string theorists work to find approximate solutions to approximate equations"--Greene gives a tour of string theory solid enough to satisfy the scientifically literate.Though Ed Witten of the Institute for Advanced Study is in many ways the human hero of The Elegant Universe, it is not a human-side-of-physics story. Greene's focus throughout is the science, and he gives the nonspecialist at least an illusion of understanding--or the sense of knowing what it is that you don't know. And that is traditionally the first step on the road to knowledge. --Mary Ellen CurtinFrom Publishers WeeklyOne of the more compelling scientific (cum-theological) questions in the Middle Ages was: "How many angels can dance on the head of a pin?" Today's version in cutting-edge science is, "How many strings... ?" As posited by s tring theory physics, strings are furiously vibrating loops of stuff. The concept of strings was devised to help scientists describe simultaneously both energy and matter. The frequency and resonance of strings' vibration, just like those of strings on an instrument, determine charge, spin and other familiar properties of energy?and eventually the structure of the universe: a true music of the spheres. There's a chance that strings are themselves made up of something still smaller. But scientists can prove their existence only on the blackboard and computer, because they are much too tiny?a hundred billion billion times smaller than the nucleus of an atom?to be observed experimentally. Brian Greene, professor of physics and mathematics at Cornell and Columbia universities, makes the terribly complex theory of strings accessible to all. He possesses a remarkable gift for using the everyday to illustrate what may be going on in dimensions beyond our feeble human perception. Just when we might be tempted to dismiss strings as grist for the publish-or-perish mill, Greene explains how they have demonstrated connections between mathematics and physics that have helped solve age-old conundrums in each field. This book will appeal to astronomy as well as math and physics fans because it probes the important insights string theory gives into hotly debated issues in cosmology. Later chapters require careful attention to Greene's explications, but the effort will prepare readers to follow the scientific advances likely to be made in the next millennium through application of string theory.

Amazon.com ReviewAs a boy, Brian Greene read Albert Camus' __ and was transformed. Camus, in Greene's paraphrase, insisted that the hero triumphs "by relinquishing everything beyond immediate experience." After wrestling with this idea, however, Greene rejected Camus and realized that his true idols were physicists; scientists who struggled "to assess life and to experience the universe at all possible levels, not just those that happened to be accessible to our frail human senses." His driving question in The Fabric of the Cosmos, then, is fundamental: "What is reality?" Over sixteen chapters, he traces the evolving human understanding of the substrate of the universe, from classical physics to ten-dimensional M-Theory.Assuming an audience of non-specialists, Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. For the most part, he succeeds. His language reflects a deep passion for science and a gift for translating concepts into poetic images. When explaining, for example, the inability to see the higher dimensions inherent in string theory, Greene writes: "We don't see them because of the way we see…like an ant walking along a lily pad…we could be floating within a grand, expansive, higher-dimensional space."For Greene, Rhodes Scholar and professor of physics and mathematics at Columbia University, speculative science is not always as thorough and successful. His discussion of teleportation, for example, introduces and then quickly tables a valuable philosophical probing of identity. The paradoxes of time travel, however, are treated with greater depth, and his vision of life in a three-brane universe is compelling and--to use his description for quantum reality--"weird."In the final pages Greene turns from science fiction back to the fringes of science fact, and he returns with rigor to frame discoveries likely to be made in the coming decades. "We are, most definitely, still wandering in the jungle," he concludes. Thanks to Greene, though, some of the underbrush has been cleared. --Patrick O'KelleyFrom Publishers WeeklyString theory is a recent development in physics that, by positing that all which exists is composed of infinitesimally small vibrating loops of energy, seeks to unify Einstein's theories and those of quantum mechanics into a so-called "theory of everything." In 1999, Greene, one of the world's leading physicists, published The Elegant Universe (Norton), a popular presentation of string theory that became a major bestseller and, last fall, a highly rated PBS/Nova series. The strength of the book resided in Greene's unparalleled (among contemporary science writers) ability to translate higher mathematics (the language of physics) and its findings into everyday language and images, through adept use of metaphor and analogy, and crisp, witty prose. The same virtues adhere to this new book, which offers a lively view of human understanding of space and time, an understanding of which string theory is an as-yet unproven advance. To do this, Greene takes a roughly chronological approach, beginning with Newton, moving through Einstein and quantum physics, and on to string theory and its hypotheses (that there are 11 dimensions, ten of space and one of time; that there may be an abundance of parallel universes; that time travel may be possible, and so on) and imminent experiments that may test some of its tenets. None of this is easy reading, mostly because the concepts are tough to grasp and Greene never seems to compromise on accuracy. Eighty-five line drawings ease the task, however, as does Greene's felicitous narration; most importantly, though, Greene not only makes concepts clear but explains why they matter. He opens the book with a discussion of Camus's The Myth of Sisyphus, setting a humanistic tone that he sustains throughout. This is popular science writing of the highest order, with copious endnotes that, unlike the text, include some math. Copyright © Reed Business Information, a division of Reed Elsevier Inc.
