Time Travel in Einstein's Universe: The Physical Possibilities of Travel Through Time

4.05  ·  Rating Details ·  1,304 Ratings  ·  72 Reviews
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,

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

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!

"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 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

Kitaba ya da Gott'un yazdıklarına kötü demiyorum, diyemem hatta, çünkü yazdıkları benim kat be kat üstümdeydi. Sadece her bir cümlesini anlayabilmek için kafamı patlattım resmen, çok ileri bir seviyeydi sanırım. O yüzden iki yıldız, anlayamadığımdan. Anlayamayıp, okumanın zevkini alamadığımdan.

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.
Mar 20, 2013 Tommy rated it liked 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.
Feb 07, 2009 Jackie rated it really liked it
This is a very readable look at time travel and the origins of the universe, and it was written by one of my astrophysics professors from this semester! He does tend to spend a lot of time talking about his own accomplishments, but I'm going to cut him some slack, since they really are quite impressive.
I also liked that he offered multiple theories as to the origins of the universe, and none of them answered the question, "Yes, but what happened before THAT?"

This is a really good book that explains many possible theories of time travel in relation to the laws of physics. It does a good job of explaining complicated theories in a manner that non-scientists (like myself) would be able to understand and provides helpful diagrams to help illustrate complicated points.

The ideas discussed are very interesting, and it is fascinating to know the many ways that time travel could be achieved if we had unlimited resources/knowledge.
Ajitabh Pandey
A very interesting, informative and well written book. Richard Gott, starts with the basic concept and ideas of time travel with an brief explanation to the scientific theories lying behind some of the Hollywood's successful movies. He further moved down to explaining the various concepts, theories and ideas behind time travel to past and to future. Linking the time travel to the beginning of the universe introduces the reader with many interesting theories and concepts.
Apr 18, 2008 Jeff rated it it was amazing
Physics for those cursed, or blessed (however you look at it), with an inability to comprehend the mind-numbing concepts of modern theories. Gott allows his readers a unique access to the theories that have been commonly accepted to rule our universe. He intersperses his explanations of Einstein's theories with pop culture references and melds these two disparate concepts into a very readable explanation of a confusing concept.

I chose this book to read for my book report in a Finite Math Class and was pleasantly surprised. I'm not a huge fan of math/physics books but this one made me rethink it. If you are wondering about time travel, go to this book. Well written and widely spread, this book will teach you a thing or two.

Following the Likes of a Brief History in Time, this book is a must read for any enthusiast of the Universe. If you've ever wondered how you can build a spaceship that doesn't move yet can take you into the future at such a rate that people living on earth see you as being immortal, this is a must read.

I particularly enjoyed the discussion in the book around the Copernican Principle and how you can technically apply it to many different phenomenon. For avid time travel physics readers there's a lot in here that you've surely heard before but also a lot of less popular but fascinating nonetheless topics.

The beginning is an excellent and approachable summary of special and general relativity. The end is an interesting soapbox preaching regarding the probable eventual state of mankind. These were the good parts. In the middle the author starts spouting off on the origins of the universe. This was rubbish and dreadfully boring.

Anything is possible if you just BELIEVE.

I picked this book up as research material for the manuscript I am working on. It is actually a very good read, an explanation in very palatable writing of the principles and theories of physics that could make time travel possible, if only our tiny human minds could figure it out the rest of the way!

I am a huge geek who believes in time travel.. and this book does a great job explaining the possibility. I pick it up once every few months and re-read certain chapters for fun. If you want to know more about time travel.. this is one of the top books on the subject. My eyes only glaze over when the math gets too complicated.

Very clear and yet sufficiently explanatory book on time travel and its link to modern physics and cosmology. While no mathematical treatment is given, there are many diagrams and detailed prose-form explanation to satisfy those interested in the topic. A must read for those who like astrophysics and theoretical physics.
