The Fabric of the Cosmos : Space, Time, and the Texture of Reality

by Brian Greene

Hardcover, 2004




New York : A.A. Knopf, 2004.


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 ourscientific 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.

In terms of popular science books, this one is simply extraordinary. Brian Greene's writing makes exceedingly difficult and advanced concepts fairly accessible to the lay person.

In particular I like how he starts off by tipping his hat to Camus' existensialist dillema but then disagreeding with his idea that knowledge from the sciences can't in fact make a difference. I'm not sure I agree, but I think Greene's appreciation of camus, and his belief that science can make a difference helps to illustrate his passion as a scientist.

While this book covers a lot of general physics the focus is on the implications for our conceptions of space and time, as the title strongly suggests.

I have not yet finished this book, but by less than half way through I have been introduced to a number of topics that I have never really come across in the popular writings of other physicists like Drs Feynman, Weinberg, or Hawking. Greene goes thru special and general relativity and orthodox qm i a delightful manner, showing all the important features, and tho he notes that he agrees with the orthodoxy on philosophic points he does not do disservice to disagreeing views, which he makes note of in the book, as well as in some of the more technical notes.

We also go through some more intricate matters which one does not ordinarily see outside of a philosophy of physics book such as the relational v absolutist stance on space "newtons bucket", Mach's response, and Einstein's update, following which we get an overview on block space-time, and how this is reconciled with the relativistic views of different observers as different angled cuts of the single block. I have never seen this approach or metaphor thoroughly hammered out in any work on popular physics. Green also argues eloquently using the notion of "updating now moments of different observers" that SR discrepancies can be seen over extremely wide spatial separations at even extremely low velocities.

Next we get overviews of entanglement and the implications for space, including some difficult ideas on the matter from eminent researches such as John Bell, David Bohm, as well as Alain Aspects results. While the mathematical details may not be all here in their full rigor, the essence of the ideas surly is.

Right now I am learning that probabilistic reasoning applied with the time reversal invariance of the laws of physics entail that entropy should be higher in the past as well as the future!

This is mind numbing stuff!

I also like the humor and references to pop culture (simpsons, etc).

Read it and enjoy it.

For months, I avoided writing something about Brian Greene's The Fabric of the Cosmos. It was complex and only suited to summary in the most superficial way. Or so I tell myself. More likely, I am not up to the task. The book is an introduction to the current scientific understanding of the nature of space and time, emphasis on the former. While I wouldn't describe it as technical per se -- lacking the mathematics that would further illuminate but also complicate the material -- it is nonetheless challenging. The material requires the motivated nonphysicist to persist and focus, and the effort is well rewarded.

Greene offers a substantive review of quantum mechanics and general relativity, both necessary to examine current conceptions of space and time. The punchline, at the risk of imprecision, is that we cannot look at space in a common sense way at all. There are important ways in which space does not involve a conventional notion of locality; quantum phenomena resist explanations that rely on the familiar behavior of quotidian reality; at the smallest dimensions space and time themselves seem to lose meaning; ultimately there is no such thing as “empty” space, as what appears empty is actually roiling with the energy of quantum fluctuations.

Having established this basis, Greene uses these concepts to paint a picture of cosmic inflation and quantum loop gravity theories, aiming to show how these prominent approaches account for space itself and the vastness of the universe.
Where is the controversy, one might ask? Ultimately, the trajectory of the book leads to Green's great personal interest in physics, string theory. We see how this theory, if true, might address some of the current mysteries in our understanding of space and time. But there are those for whom them’s fightin’ words. Some argue that string theory lacks the quality of falsifiability, and as such cannot be taken seriously. If you are a staunch adherent of this position, you no doubt do not need to be reading this review.

The book was excellent and I highly recommend it. I found it all rather thrilling.

Carl Sagan and his Cosmos marked my childhood with great memories in 1980s, and it's great to see the tradition of successful scientists laying out a great narrative is alive and ticking in books such as this one by Brian Greene.

I'm a bit late to the party, so reading the book felt like a time travel. Having read it more than a decade after it's been written, I know that Higgs boson has been discovered, gravitational waves have been detected, and NASA's Gravity Probe B mission has been accomplished. Does that fact take anything away from the book's worth? Well, it depends on your perspective, but I would say "no, not at all!". Lacking the descriptions stellar scientific achievements that occurred in the last 13 years, the book is still a very good exposition of our current understanding of our universe and reality.

My only criticism can be summarized as the following: it's good for a popular science book to stay away from the technicalities of complex physics theories, but I think putting a bit of math in the end notes hardly helps, simply referring to the relevant sources for details would make it more concise. Moreover, I'd expect a more thorough description of loop quantum gravity, instead of a mere few pages of introduction and a very short comparison with string theory.

Slightly worse than it's "predecessor", but then we all know that it would be hard to beat one of the best science books out there.

More dense, the advances in the theories are really took into context without sounding too draconian to strangers like me.

Greene, professor of physics and mathematics at Columbia University, and a superstring theorist explains the stuff of reality. By skillful use of diagrams and analogies he succeeds even for non-mathematicians like me. He also goes on to explain of what the world might be made. In other words, what science knows by experimental proof and what has yet to be proved by experiment. And most puzzling is the experimental fact that the rules of movement for the big things in the universe, people, planets, stars and galaxies are quite different from the laws of the very small things in the universe, atoms and sub-atomic particles, which follow the rules of quantum mechanics.

Humans experience three dimensions of space and one of time, and while we can go up or down, forward or backwards, left or right in space we can only travel forward in time. But are these dimensions the real stuff of the universe as Isaac Newton and Albert Einstein insisted or just a linguistic expressions of relationships as Gottfried von Leibniz argued? Following time’s single direction Greene leads the reader back to the beginning of the universe, the Big Bang and then forward to a cosmos that may have as many as eleven dimensions. It’s quite a trip.

The second book on string theory by Greene, and actually much easier to read. It is probably a good idea to start with this book, and not "The Elegant Universe". Towards the end of the book, some very intriguing theries are discussed, these alone are worth reading this book. It will probably keep you wondering about the world (or rather, universe) we live in for quite a while.… (more)

What an amazing book. Brian Greene is amazing, too -- he can take incredibly complex concepts, and write about them in a way that someone who doesn't have a PhD can understand.
LibraryThing member fpagan
Major effort and (as science books go) bestseller, describing the current frontier of fundamental physics (and cosmology). Exceptionally clear and thought-inducing.
LibraryThing member neurodrew
Another fat book on the physics of cosmology and relativity, explaining, in some vague way, current theories and problems of grand unified theories and cosmology. Absorbing and pleasant to read, but leaves me with a curiously unfufilled feeling, as though I was window shopping rather than learning things. I read about the quantum measurement problem, about paradoxes of collapsing wave functions, and again about 11 dimensional strings as a way of unifying general relativity and quantum mechanics.… (more)

This book gives a wonderful, detailed overview of the current state of thinking regarding certain areas of the theoretical physics world. Although I found much of the book extremely interesting, and I was constantly going to Wikipedia and other sources for more info, I still found much of the book extremely drawn out. It could have been much shorter.

In particular, my favorite areas of the book were:
- The description of Einstein's General and Special Theories of Relativity
- The sections on Cosmology related to the Big Bang and Inflationary Theory
- Quantum Fluctuations and elementary particles
- Parts of the String Theory section and membranes
- Time travel theories

The most laborious section in my mind was Greene's slow approach to entropy. Anyone with even some level of scientific study would have found this section to be boring and plodding. I can understand the need for covering entropy in his overall approach to "time's arrow" but it should have been seriously reduced in word count.

I would recommend this book to people with more than passing interest in space, quantum mechanics and physics. It makes for an excellent overview for a general reader but perhaps with some searching, books of similar quality (and shorter) could also be found.

follow up to his prior book, The Elegant Universe. This one is a little more simplistic in some ways, using very imaginative analogies to explain complex theoretical physics principles. I found it very enjoyable and a nice companion book to The Elegant Universe.

Fabric of the Cosmos sets upon the idea that what we se everyday is a veil, that there is a true reality that goes beyond our everyday perceptions. The book starts out with very basic concepts that are easy to grasp and the heat gets turned up from there. There are some mind-bending questions asked, “Why does our memory only remember the past, why not things that are yet to happen?” Brian Greene attempts to explain these high-end concepts using real world examples (a la Star Wars and The Simpson).

The best example comes in the introduction where he gives the example of the rose. On its own we can appreciate its beauty, but using the knowledge of physics, we can be amazed at its existence so much more. That example demonstrates the passion of Brian Greene’s book, but it also reminded me of an episode of The Simpson where the teachers have gone on strike. One of the scientists is teaching a kindergarten class and is using a kids bubble popper. The kids want to play with it, but he retorts with something like, “You won’t appreciate the science of it as much as I do.”

I thought another example from the book is a good explanation of what it is like to read the book. Greene explains about space-time, in that, you are either taking up space or time. When you are resting, you are taking up space, when you are moving, you are taking up time. This kind of concept really blew my mind. I always like the concept of time travel. Scientists provided this theory by sending a plane around the world with an atomic clock to prove the point. When the plan landed the clock was one/one billionth of a second behind. It’s an interesting proof, but my first reaction was, “that’s it?”

I comprehended the first three-quarters of the book. While the book provides mind-blowing facts, you cannot discern them in everyday life, which is the point of the book. It's a fascinating history of physics told in laymen's terms. It’s fascinating to a point, but many of the concepts I couldn't fully comprehend.

This is a terrific book. I thoroughly enjoyed every page written by distinguished string theorist Brian Greene, who also wrote the book and Nova TV series, "The Elegant Universe", which is available in paperback. Some of the string theory in "The Fabric of the Cosmos" is repetitive of the content of the earlier book. This guy not only knows his stuff, but he also explains very difficult physics using examples and analogies that are inventive and humorous (for example, characters and situations from "The Simpsons" pop up in several different contexts). Do not get the idea that "The Fabric of the Cosmos" deals only with arcane particle phenomena that are completely irrelevant to everyday life, or that it oversimplifies to the level of cartoons. On the contrary, Professor Greene elevates the reader's thinking to the ultimate nature of reality. Over the past couple of years, I have read a number of books that purport to bring relativity, quantum mechanics, and cosmology to the non-physicist, but this is the one that I enjoyed the most. The only thing I would criticize about it is that the black-and-white illustrations (and there aren't a lot of them) don't seem to have been reproduced very well.… (more)

Finally finished this book! It's taken me six months to read this on and off.

Brian Greene writes very clearly, using imagery that is easy to understand for the armchair reader. The book does require concentration and the assimilation of one part before moving on to the next, which is why I only read it in small doses. However it is well worth the effort, providing a clear overview of 'the fabric of the cosmos' from Newtonian physics to superstring theory and beyond.

It is, quite simply, a riveting read.

I like the fluidity of Greene's writing, especially since he skips all the "unnecessary" details like calculations and such. However, I don't quite agree with some comments that this book is accessible to even people who have never before studied physics. Greene may have simplified, but the book is still rather academic in my opinion.… (more)

An unbelievable insight into the very fabric of what we consider to be "reality." This book will undoubtedly change the way you think about our "three dimensional" universe forever.
LibraryThing member MarjorieThelen
I guess you'd say I'm currently reading this book. It is the kind of book one reads in small doses over several years. The ideas are so mind expanding they make me a little crazy. Greene is a superb writer for the non-science person. I read The Hidden Reality this year. I also saw NOVA's recent four part series with Greene as narrator on the same subject. Well-done. I also have The Elegant Universe on DVD. I would recommend any of his books.… (more)

I really enjoyed this book, and I would have given it 4 stars but I almost wish it had been more scientific. At times it felt like the use of metaphor was too distracting from the scientific concepts being explained and I came away with no real understanding of the topic but instead a rather convoluted concept about frogs in a hot metal bowl filled with worms...I will leave you to figure out what concept that was regarding....… (more)

Marking this as finished even though technically I still have two more chapters left -- they're even chapters I look forward to reading. But I know I'll be coming back to this and I wanted to move on to other reading for now.

Having said that, this seems like a good overview of the current (well, as of the date of publication) state of the game in physics. I can't say that for certain of course, but it left me feeling like I had some understanding (not enough -- hence my suggestion I might return to it) of the current issues and the current focus of research for cosmology.… (more)

For pop science you could do much worse than this.

This is his second book. I finished this book around the same time I was watching the new Cosmos series on Fox. (It's hard to believe that Seth McFarlane, the man behind Family Guy, is one of the producers of the new Cosmos. I'm still waiting for Stewie to show up, or for a Cosmos parody on Family Guy. But I digress.) Like Carl Sagan and Neil Degrasse Tyson on Cosmos, Brian Greene is attempting to make science understandable to those of us who don't have advanced science degrees. Dr Greene uses a lot of pop culture references to illustrate his points. He seems to have a special fondness for the Simpsons. It's a little more complex, though. He's trying to explain the basics of string theory, with its theories of 10-dimensional space and quantum lengths. It can be a little slow going at times. He saves most of the mathematical equations for the footnotes. I'm not sure it's fully understandable to everyone. I had trouble with it myself. Some updates from the text. The large Hadron collider was finished, and the Higgs particle was discovered. Also, scientists recently discovered ripples from the original big bang. Dr Greene knows about pop culture. (He's appeared on the TV show The Big Bang Theory making fun of himself.) He does well in this book. It's just the subject matter that can be daunting.… (more)

Brian Greene's work is comprehensive collection of scientific understanding with regard to origin of universe, grand unification, and concept of space/time. Book presumes basic awareness of key concepts (which aren't difficult to have if one has passing interest in this topic) but provides very detailed and scientific approach to whole lot of ideas and experiments designed to test those ideas. In the end, book is mind-blowing and leaves one marveled at world we inhabit. I was familiar with key themes but systematic approach still helped deepen the appreciation of, for example, experiments in LHC or multiverse theory. Recommended read for one interested in this topic.… (more)

I'm not a Physicist, so Quantum Mechanics is not what I would've done / learned as part of my regular 'work life'. But this documentary explains the basics of Quantum world in a way that is easily absorbed by non-Quantum people (or 'lay men' according other Quantum physicists).

The new and open-ended perspective regarding Multiverses is simply mind boggling and yet I'm curious to know more about it.

The visuals and graphics used in the documentary uncomplicates the understanding of these intricate and composite theories.

But I've got to say this, I felt a lot better reading these concepts in The Elegant Universe by the same author.

I fully admit i struggled with some of the concepts discussed in this book - Brian Greene makes it as friendly as possible but some of the terminology just went over my head - still I did finish with a better understanding than I started with.
I found that the multiple ways of describing various concepts sometimes useful but mostly repetitive. But I can see why they are there as everyone will interpret situations diferently.
The second half of the book which goes into quantum theory and supersting theory the most difficult to understand but i think this is mostly because the concepts are so alien to our everyday understanding of life.

Good book with some astounding thoughts on where physics and the study of space-time are going. Above my head but there are pearls of information that suggest the immensity and the unseen reality about us all. But a long read.
