Endless Universe: Beyond the Big Bang -- Rewriting Cosmic History by Neil Turok,Paul J. Steinhardt



Should their approach someday be confirmed, it would result in a major upheaval to our understanding of how everything-space, time, and matter-came to be. -Brian Greene, author of The Elegant Universe and The Fabric of the Cosmos. For the past twenty years, the combination of the big bang theory plus inflation has offered cosmologists an unbeatable one-two knockout punch. Steinhardt has been a public vocal critic of inflation going so far to say that it isn't even science since one can get just about any prediction from the theory since it is so general in nature. This is also discussed in the book. My disagreement with the theory is that it is based on string theory and brane theory.

In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking Cyclic Universe theory.

Endless Universe is so important because it recognizes how our views change with almost every new development. It looks ahead and asks the question "Hey, are we wrong? What if there wasn't a big bang? Did something else happen? What's this Guth's rabbit? How can we develop an alternate explanation in case something else really happened" which cogent evidence seems to indicate. It's not the easiest book in the world to follow but it is Physics so what do you expect? But it is riveting and quite fascinating and worth a read.

by Neil Turok and Paul J. Steinhardt. Two prominent players in physics and cosmology (Steinhardt of Princeton and Turok of Cambridge) lay out in a very readable popular science book a fundamentally new theory, which started as the Ekpyrotic universe (terrible name) in 2001 and has evolved into the cyclic universe, a theory that challenges the prevailing big bang theory. The big bang theory in its current form envisions a multi-universe with endless space of which our universe is only a tiny part. The cyclic model envisions repeating versions of a single universe spread out over endless time

Endless Universe: Beyond the Big Bang infinite collisions between our universe and a parallel world According to this theory, the Big Bang was not the beginning of time but the bridge to a past. PAUL J. STEINHARDT is the Albert Einstein Professor in science and on the faculty of the departments of physics and astrophysical sciences at Princeton University. NEIL TUROK is professor of Mathematical Physics at Cambridge University. He was born in South Africa and read Natural Sciences at Churchill College Cambridge before taking a PhD at Imperial College. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly.

Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” —Wall Street JournalThe Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place.In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets.Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos.  It is a “theory that could solve the cosmic mystery” (USA Today).

This book is about the ekpyrotic model for the evolution of our universe. It states that about every trillion years or so our universe recycles itself.As the authors say in their glossary "ekpyrosis: a collision between two branes that produces a flat, expanding universe filled with matter and radiation, with a nearly scale-invariant distribution of density inhomogeneities." It is a competing theory to the better known inflationary model of the universe. Both the authors are practicing cosmologists with Steinhardt at Princeton and Turok at the Perimeter Institute. Steinhardt made early contributions to the inflationary model in the early 1980's and is therefore well aware of the strengths and weaknesses of the inflationary model. This is a well written book and was a pleasure to read. If you are interested in cosmology this book is a must for you. The level of this book is such that any interested high school student should have no trouble reading this book.

This book is written in a casual style and mentions how the authors first got the idea for their theory while they were both attending a lecture on the overview of string theory. They both went up to the speaker after his talk and asked him questions about strings and branes. Later the authors met at a small physics conference in Finland and started to work out the details their theory. The book describes the various questions that must be overcome such as flatness and thermodynamics. In the past various cyclic models of the universe have been proposed but they were later shown to have flaws. In careful precise wording they explain how they were able to overcome all the previous questions with their new model.

As expected they describe very well the inflationary model since the book compares the two models closely. One of the main differences being that their model has small if any primordial gravitational waves which have been in the news since March 2014 because of the BICEP2 cosmic microwave radiation data which initially claimed to have observed these gravitational waves to only latter say that their results could also be explained by galactic dust. The physics community awaits further data on this subject.

Steinhardt has been a public vocal critic of inflation going so far to say that it isn't even science since one can get just about any prediction from the theory since it is so general in nature. This is also discussed in the book.

My disagreement with the theory is that it is based on string theory and brane theory. There have been no experimental tests that have every shown that string and brane theory have anything to do with reality. There are two wonderful books that show the problems with string theory. They are Lee Smolin's "The Trouble with Physics" and Peter Woits "Not Even Wrong". If anything since this book was written string theory has lost some of the luster it had back in 2007. Nevertheless I would recommend this book since it is quite educational and very well written.

This is a very good book both on the classical model of the Big Bang Theory and on the authors' alternative theory about how the universe began. I am not done with it, but I would say that unless you do not know the Big Bang Theory, you have to spend a lot of time listening to the theory you know before you get to the alternative one posited by the authors. Still, I am impressed by the detail, and by the notion of highly respected physicists being willing to challenge the accepted wisdom with an alternative scientific theory (no, not creationism or a non-scientific explanation). But again, unless you are new to the Big Bang Theory, you will have to read for a long time to get to the new theory and information.

An excellent review of modern cosmology, including the debate between proponents of inflation, and those of its opponents, who back the cyclic models. What is depressing and unfortunate is that cosmologists are no closer to resolving the debate more than a decade after the book was written. Oh well...the authors suggest we will know in less than 88 more years so that is something to look forward to.

An interesting view of a relatively recently developed theory of an 'episodic universe’. That is a universe that is cyclical and that recurrs, in this case from big bang to big bang. Written in language that one does not need to be a physicist to understand.

We change our clothes every day, we change our lives every now and then, but we seem to change our philosophical view on the universe twice a century. The more rapidly we develop tools that help us measure spans of the universe and look back further in time the more our views enhance or change. Endless Universe is so important because it recognizes how our views change with almost every new development. It looks ahead and asks the question "Hey, are we wrong? What if there wasn't a big bang? Did something else happen? What's this Guth's rabbit? How can we develop an alternate explanation in case something else really happened" which cogent evidence seems to indicate.
It's not the easiest book in the world to follow but it is Physics so what do you expect? But it is riveting and quite fascinating and worth a read.

This book gives the history and details, in everyday language, of what may turn out to be the two leading theories of the universe.
At least so far. For all the hype about getting close to a "Theory Of Everything" over the last 30 or more years, I wouldn`t be
surprised if these were to eventually bite the dust as so many others have before. But still, the ideas presented are interesting.
And who knows, one of them might actually be right, or at least point in the direction of the right anwsers.
The book is well written, easy to understand, and in everyday language. A fun read.

This is one of the most well written, balanced, non mathematical descriptions of physical cosmology I've read. I recommend it for both lay readers and scientific readers. I gives an excellent qualitative explanation of aspects of M theory that can help students of M theory. It is heads and shoulders above other explanations of cosmology I have read. I highly recommend it.
