The Fabric of the Cosmos: Space, Time, and the Texture of Reality
From Brian Greene, one of the world’s leading physicists and author the Pulitzer Prize finalist The Elegant Universe, 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 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.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

Customer Reviews 619 of 632 people found the following review helpful Record Setting, March 4, 2004 By David Kegen (The Sunshine State) – See all my reviews I’ve never written a review before, but I have enjoyed browsing reader’s comments on books I read or teach from. While reading the review that claims this new book to be a “dumbing down” of The Elegant Universe, and to have “no new material”, I felt I had to set the record straight. For the record: I teach Physics for Poets class in a local community college, and use The Elegant Universe as one of our books. Next year I will add Fabric of the Cosmos to the syllabus since it has at least 80% new material, and the overlap with The Elegant Universe is done in a new way that I have not seen in any other book, The Elegant Universe or otherwise. The reviewer says that “200 pages are spent reviewing Newton and Einstein” which is a factual error. It is just over 50 pages, and a fascinating new angle known as Mach’s principle is used.
For the reviewer to say that “spooky action at a distance” is in Elegant, is also a factual error. He must be thinking of another book. This (huge) subject, entanglement, was not covered in the Elegant Universe as I know for sure, since in the past I have had to assign other books for these ideas. I might add that the discussion of entanglement in Fabric goes far ahead of any other since it proves Bell’s theorem, without math! I didn’t think that was possible! The main theme of The Arrow of Time which runs through Fabric, is not touched on at all in Elegant, nor are the questions of whether space and time are real or just ideas.If someone is looking for a direct sequel to Elegent, this is not that book. Fabric is a monumental work of its own and should be read as such. For other suggested readings: Kip Thorne’s Black Holes and Time Warps, Janna Levin’s How the Universe Got its Spots. The One Book to Read, March 16, 2004 By George Shermann (Toledo) – See all my reviews I loved The Elegant Universe.
I loved The Fabric of the Cosmos even more.In showing the state of the art of unified theories, The Elegant Universe explained alot of physics with unsurpassed clarity. Yet, there were discoveries I had read something about in other books that The Elegant Universe did not discuss, and I longed for Brian Greene to bring his powers of explanation to these subjects too. (I even wrote him an email saying so). The Fabric of the Cosmos answers my longing in abundance. This book not only covers relativity but also the long debate about Mach’s principle and what "space" means. It covers quantum mechanics, but goes further by taking on the debate regarding observers and measurment, and provides the clearest, most understandable discussion of quantum entanglement (the "EPR paradox) that I have ever seen in print or any other format. The chapters on cosmology are equally great, and the final sections bring the work on unification and string theory right up to the moment. I can’t say this is an easy book, perhaps a little easier than The Elegant Universe, but definitely a challenge. It is worth it. By the end, the poetry of the universe is yours to behold. 140 of 144 people found the following review helpful I happened by chance on The Elegant Universe two years ago during one of my "learn the newest" in physics stretches. I’d read many popularizations to that point, but none could hold a candle to The Elegant Universe. The chapters on relativity and quantum mechanics were, arguably, the clearest treatment |
