In this fascinating book, the renowned astrophysicist J. Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, ...more

I read this book and I need to re-read it again. This is one of those books that after you read it the first time, you are completely enlightened. You know you probably missed some important details so when you read it a second time, everything you missed pops out at you. For anybody really wanting to understand the different theories behind time travel, this book is for you. There were times when I just sat and pondered about what I just read for about an hour.

traveling through time is just a technological problem .... after reading this book you will realize that there are way more methods to travel through time than you have ever thought ...

دعني أخبرك بسر،أنا و أنت و الجميع مسافرون عبر الزمن ،كيف هذا ؟ سأخبرك لاحقا و لكن الأن سوف أشاركك بعض الأفكار المتفرقة عن موضعنا هذا .

دعني أتحدث عن الزمن قليلا ، مفهوم البعد الرابع اي الزمن ظهر لاول مرة في رواية آله الزمن عام 1895 علي يد هربرت جورج ويلز ، اي انه ظهر أدبيا أولا ثم تنبنته الفيزياء ، أليس ذلك مشوقا ؟. حسنا دعني أنبهك أن هناك فرقا جوهريا بين البعد الزماني و الابعاد المكانية الثلاثة ، فالبعد الزماني له إشارة سالبة .
علم الفيزياء حاليا يعترف بأربع أبعاد محسوسة كما سبق ذكر

No book is without its charm although this one comes pretty close. Granted, diehard and gullible enthusiasts of space travel no doubt think differently but for the more skeptical they will find little worthwhile here except a gift for explaining the theory of relativity--both special and general relativity--with clarity and simplicity that few can and thus the latter part of the fourth chapter makes the book worthy of the purchase. For those seeking a book that will advocate the resumption of sp ...more

We instinctively know what time travel is, but how would you define it in physical terms? How is time travel to the past different from time travel to the future? And does it fit in our universe? If not, how can we know about the future?
Author tries to answer these questions in a graphic way, and he succeeds! The book also takes a suprising turn towards the end, making it an extra satisfying read.

I enjoyed this book about the physics of time travel, although at times I felt like the author was dealing with some pretty speculative stuff and presenting it pretty confidently as fact.

For instance, he describes a method of creating a "time machine" that would, in theory, allow a spaceship to reach a destination faster than light. To set up the process, you position two cosmic strings of infinite length near each other. Oh, is that all I need? Two cosmic strings of infinite length. Let me chec

This book is more than just another popular treatment of special and general relativity and quantum mechanics. Gott applies these theories to time travel in a 'not-wrong' fashion, i.e., consistently with we already know to be true. He discusses the theoretical possibility of time travel to the future and to the past (spoiler: both may be possible), and even describes the construction of time machines that do not violate the laws of physics as we now understand them (spoiler: you may need the ene ...more

Professor Gott starts with the familiar paradox of a time traveler going back and killing a grandparent, adds Einstein's general theory of relativity, and walks the reader through much of current physics theory while seeking ways time travel might be permitted. Along the way, he manages to use almost no mathematics through a set of simple, expressive diagrams. An excellent popular science book!

Great book. Perfect starter book to anyone interested in time travel. It posits many of the theories and paradoxes of time travel while being quite informative. The book may be tough for some readers if not of a science background, but it has excellent metaphors that help the reader along.

"It is the time traveler's secret"

This was one of those books I thought I'd never read. I don't even recall why I started it. I mean, the idea of time travel intrigues me, sure (Thank you, Doctor). But I didn't expect it to be a good read. Get it?

Well, unlike that tragically executed pun, this book was awesome. It's just so timey wimey and incredibly explained. You don't need to know rocket science or quantum mechanics to understand what JR Gott is saying.

However, if you're going to get into thi

This is a very good book on physics and time travel by somebody who has written a lot of influential papers on the subject. The beginning is very witty and frames the questions through the use of time travel in fiction and film but then it quickly delves into hard science. Early chapters will just be a review of Einstein for many people, but the later chapters are filled with interesting ideas that I wasn't really familiar with. I think the lst chapter, which is about predicting the future, rea ...more

Really interesting stuff. Some is too complicated for me, well most, but the writer really tries to explain through diagrams, film and book examples and any other helpful antidotes. The chapter that tackles what was there BEFORE the big bang was fascinating but ultimately quantum physics and string theory lost me. Still its thrilling that people are thinking this hard about something that seems impossible....

One of the two best non-fiction books I have ever read. Read it several years ago and it continues to influence my thinking. This book touched me not just intellectually, but surprisingly spiritually as well. It is one of two books I always recommend for anyone seeking a higher understanding and connection with the eternal. There truly can be a spiritual aspect to science.

I had a bit of a difficult time reading this book, as I had to concentrate way too much. Hey, I’m no Einstein. But I do love time travel, so I stuck with it to the end and was rewarded with lots of interesting bits how time travel may be possible, about the Big Bang, the creation of the universe and the Copernican principle. Science rocks!

A good read, but...

This was a good read. I am not a physicist, but I was able to understand Gott's arguments well, so in that respect it was a good book, but, there were a number of formatting and spelling errors that made the reading a bit tedious in parts. If you're interested in the physics of time, then it's worth the money.
Sharon Reamer
A really nice quirky overview on the possibilities of time travel from a physicist's point of view and a little history of science thrown in as well. I found it engaging and fun and easy to read and wished it would have been more in some places and less in others. If you've read Kip Thorne's books on time travel (and black holes) and enjoyed them, you'll like this one, too.

Interesante libro donde de una manera lo más científica posible se intenta demostrar gracias a las teorías de Einstein que el viaje en el tiempo es posible. Tiene conceptos curiosos y realmente da que pensar en que el viaje en el tiempo es posible.

I had thought the book would provide interesting insight into the possibilities of time travel, which it did in a sort, but seemed to get lost in a lot of detail that made it difficult to get through.

This book was NOT good. When I first saw this book and read the title, I thought this was about time travel. I was WRONG! This is a book filled with the author telling us about a bunch of fictional stories and how they relate to time travel, or how impossible it is to time travel without an explanation. I was very fascinated for a little while, but when he started talking about some of his ridiculous theories, it wasn't interesting anymore. It did not seem like he knew what he was talking about ...more

I took upon reading this book as a mental challenge and it was a challenge alright! First, I'd like to say that I have always been a huge fan of Einstein's work, however, this book convinces me that he was not just a genius but one who was determined to follow his inspiration. Gott explains into detail Einstein's three biggest ideas/theories and how they contribute to the possibility of time travel - past and future.

I can imagine there'd be a few critics out there dismissing the theories in thi

What ages would I recommend it too? – Fourteen and up.

Length? – Several days to read.

Characters? – Not really.

Setting? – Semi real world. Science on the scale of the largest and smallest particles.

Written approximately? – 2001.

Does the story leave questions in the readers mind? – Reading to read more theories.

Any issues the author (or a more recent publisher) should cover? No.

Short storyline: The first chapter was really good and covers many types of media (books and movies) that give examples

I can't say I understood it all. But for explaining extremely complicated concepts to a layperson, Gott did fabulously. This book also deals with such fun as the beginning of the universe. The whole "universe created itself" concept is excellent.

SPOILER: (can one spoil a nonfiction science book? I honestly don't think so, which is why I'm not checking the box)
It sounds like time travel is theoretically possible, but we're going to have to get a LOT better at space travel first. Also, no tr

This started off as a fascinating read however I am going to have to put it to one side for the time being. Despite being billed as for the lay reader the scienctific writing was very detailed and way beyond my grade D GCSE science. An interesting survey of time travel in film though. Whoever it was who told me that Bill and Ted's excellent adventure was about a road trip round America clearly had never actually seen it.

The first few chapters were incredibly interesting in that they actually went through various time travel possibilities and explained various paradoxes. Then the book took a long time to go through a physics overview about string theory, laws of motion, and higher dimensions that has been done better in other books and didn't really talk about time travel. The last chapter or so got back on track but I wish the book just stuck to time travel theory.
