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? The author 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, Green shows how recent cutting-edge developments in super-string and M-theory may reconcile the behavior of everything from the smallest particle to the largest black hole. This startling vision culminates in the vibrant eleven-dimensional "multiverse," pulsating with ever-changing textures, where space and time themselves may dissolve into subtler, more fundamental entities.

The Author 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, Green Shows How Recent Cutting-edge Developments In Super-string And M-theory May Reconcile The Behavior Of Everything From The Smallest Particle To The Largest Black Hole. This Startling Vision Culminates In The Vibrant Eleven-dimensional Multiverse, Pulsating With Ever-changing Textures, Where Space And Time Themselves May Dissolve Into Subtler, More Fundamental Entities.

From the Publisher 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 ElegantUniverse 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. With 146 illustrations This is simply another great book on the cosmos by Brian Greene. I previously read Greene's book "The Elegant Universe" and I think at enjoyed this one even more. Greene packs as enormous wealth of information in his books. Quite frankly, it takes me considerably longer to read one of his books than most other books I read because of the volume of new information I am learning. Greene has done a fantastic job of explaining the cosmos in this work. His explanations are detailed and lengthy enough to thoroughly convey the concepts discussed. There were many concepts that I read about in other books which were clearly delineated in this book, and I went away with a much better understanding. Green covers a wealth of information about the cosmos such as wave probability, uncertainty, spin, entanglement, the flow and direction of time, quantum erasure, decoherence, symmetry, the various forces of nature (strong, weak, electromagnetic, gravity), Higgs field, the big bang, inflation, dark matter, dark energy, entropy, string theory, branes, time travel, the future, and much more. If you want to get a good education about the universe we live in, I high recommend Green's books. NATIONAL BESTSELLER • From one of the world's leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) 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 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. 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 instantaneously coordinate their behavior, 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. contents......Page 3 preface......Page 6 I REALITY ARENA......Page 11 1 Roads to Reality......Page 12 2 The Universe and the BucketT......Page 38 3 Relativity and the Absolute......Page 59 4 Entanglind Space......Page 108 II TIME AND EXPERIENCE......Page 168 5 Frozen River......Page 171 6 Chance and the Arrow......Page 191 7 Time and the Quantum......Page 236 III SPACETIME AND COSMOLOGY......Page 287 8 Of Snowflakes and Spacetime......Page 290 9 Vaporizing the Vacuum......Page 332 10 Decontructing the Bang......Page 360 11 Quanta in the Sky with Diamonds......Page 402 IV ORIGINS AND UNIFICATION......Page 428 12 The World on a String......Page 429 13 The Universe on a Brane......Page 493 V REALITY AND IMAGINATION......Page 541 14 Up in the Heavens and Down in the Earth......Page 544 15 Teleporters and Time Machines......Page 572 16 The Future of an Allusion......Page 615 Notes......Page 646 Glossary......Page 698 Suggestions for -Further Reading......Page 706 Index......Page 708 A magnificent challenge to conventional ideas' Financial Times'I thoroughly enjoyed this book. It manages to be both challenging and entertaining: it is highly recommended' the Independent'(Greene) send(s) the reader's imagination hurtling through the universe on an astonishing ride. As a popularizer of exquisitely abstract science, he is both a skilled and kindly explicator' the New York Times'Greene is as elegant as ever, cutting through the fog of complexity with insight and clarity; space and time become putty in his hands' Los Angeles Times Book Review
