From the bestselling author of The Elegant Universe, Brian Greene's The Fabric of the Cosmos takes us on an irresistible and revelatory journey through the biggest of the big questions. What is reality? Could we exist without space and time? Can we travel to the past? What are the limits of the universe? Brian Greene has made the mysteries of space and time accessible to millions with his acclaimed writings and award-winning TV series. Now he reveals a world more beautiful and bizarre than we could have imagined, where 'dark matter' reigns, space warps and wiggles through eleven dimensions, minute particles dance, fizz and teleport across vast distances, everything is made of vibrating strings and, like an ant on a lily-pad, we may be floating on a sliver of spacetime. Revealing new layers of reality that lie just beneath the surface of our everyday lives, this grand tour of the universe will make you look at the world in a completely new way. 'A must-read' Sunday Times 'Greene takes us to the limits of space and time' Guardian 'Sends the reader's imagination hurtling through the universe on an astonishing ride' The New York Times Brian Greene is well known to many fans as a populariser of theoretical physics. He is the author of the bestselling books about string theory, The Elegant Universe, which was a finalist for the Pulitzer Prize for nonfiction, The Fabric of the Cosmos, and The Hidden Reality. Educated at Harvard and Oxford, he has taught at both Harvard and Cornell and has been Professor of Physics and Mathematics at Columbia University since 1996.

Review:

As a boy, Brian Greene read Albert Camus' The Myth of Sisyphus 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'Kelley

From the Inside Flap:

From Brian Greene, one of the world?s leading physicists, comes a grand tour of the universe that makes us look at reality in a completely different way.

Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past?

Greene uses these questions to guide us toward modern science?s new and deeper understanding of the universe. From Newton?s unchanging realm in which space and time are absolute, to Einstein?s fluid conception of spacetime, to quantum mechanics? entangled arena where vastly distant objects can bridge their spatial separation to instantaneously coordinate their behavior or even undergo teleportation, Greene reveals our world to be very different from what common experience leads us to believe. Focusing on the enigma of time, Greene establishes that nothing in the laws of physics insists that it run in any particular direction and that ?time?s arrow? is a relic of the universe?s condition at the moment of the big bang. And in explaining the big bang itself, Greene shows how recent cutting-edge developments in superstring and M-theory may reconcile the behavior of everything from the smallest particle to the largest black hole. This startling vision culminates in a vibrant eleven-dimensional ?multiverse,? pulsating with ever-changing textures, where space and time themselves may dissolve into subtler, more fundamental entities.

Sparked by the trademark wit, humor, and brilliant use of analogy that have made The Elegant Universe a modern classic, Brian Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
