### ⭐⭐⭐⭐⭐ 







  
  
    A very interesting and informative book for anyone interested in time travel.
  

*by J***E on Reviewed in the United States 🇺🇸 on December 26, 2020*

Even though I am well into my senior years, I have had an interest in astronomy, space travel, cosmology, physics and time travel since my youth. When I saw this 291 page soft cover book on Amazon for a bargain price (Time Travel in Einstein’s Universe: The physical possibilities of travel through time by J. Richard Gott lll) I purchased it.I just finished reading this very interesting and informative volume and found it to be fascinating. Even though this book is filled with scientific complex formulas based upon physics; nevertheless, the author does an excellent job of making the various hypothesis easy to understand when it comes to the possibility of time travel.This book is organized into five detailed sections covering the following areas:  Dreaming of time travel, time travel to the future, time travel to the past, time travel and the beginning of the universe, and report from the future.  The end of the book is filled with notes and annotated references. There are also several illustrations showing how the various hypotheses may in time become actual working scientific theories.If you are interested in the scientific study of the possibility of traveling through time you may want to check out this intriguing book.Rating: 5 Stars.  Joseph J. Truncale (Author: Tactical Principles of the most effective Combative Systems).

I read a good percent of what gets published on cosmology, astrophysics and related topics. Skipped this book years ago because I guessed it was probably more hype than science. Lately I was caught up with what was published, and so for a few bucks I picked up a used copy. It was an interesting read, and I enjoyed it as a fun read. However, don't be confused by the other reviews here. This is not a legitimate thesis on time travel. The book, enjoyable or not, is total nonsense. It is not even the equivalent of writing about the "science of Star Trek" because at least I hear that in that book they reveal why things are impossible or impractical. Not so with J. Richard Gott in his effort to popularize the possibilities of time travel. I don't want to slam his book, but the reader should approach it in the same mind set as Alice in Wonderland. Lets begin.Gott evokes Richard Feynman's work on page 16 and within three sentences progressed through "so perhaps", "as far as we understand", "if that is true" and jumps to "That's because all the possible universes exist." I don't know what to say about that, I guess I am just a little dumb founded. He then starts an exploration into science fiction including Bill and Ted's Excellent Adventure etc etc. for various purposes to support his conjectures but does give away that he knows how silly this all is with things like, "Permissible in theory, macroscopic jinn are improbable." We should hang on to that point for later, although under his attention to "Star Trek an the Concept of Warpdrive" I think things go completely off the sanity scale. On page 31 he points out that some things are only true on the "subatomic scale". Yup, lets hang on to that one for later too. Gott is now ready to discuss the future, and how "you" and your space ship simply need to travel at 99.995% the speed of light, saying if we can do it to a proton we can do it to an astronaut. Wow, that is so wrong on so many levels I just can't even begin. If you young astronauts out there want to believe that, don't. In the preceding paragraph he had pointed out there are naysayers. Gott calmly starts throwing around energies in his theories that boggle the mind and quickly deplete the stars of our galaxy. However, if you look close on page 59, he does say, "Time travel to the past would therefore imply exceeding the speed of light at some point, which is not allowed by special relativity", but that is of course a minor point in a book about time travel and is quickly forgotten. He speaks of "ancient Aboriginal wisdom" in support of a 5 dimensional universe. (p. 63) Gott starts planning "you" taking a trip through a wormhole. One little diddy that caught my fancy was "A super civilization could always manipulate such a gravity loop by flying massive spaceships near it until it acquired the right spin and assumed the desired shape. (p110), and casually discusses a loop requiring more than half the mass of the galaxy. At page 115 we are "traveling inside such a rotating black hole" - which we might do if we tossed away all real physics. On p. 123 we are jumping into worm holes, and 127 move on to tachyons, imaginary particles that do not exist and nobody thinks they exists. Pretty much as other reviewers have commented, the remainder of the book has nothing to do with time travel. Unfortunately this book is not a book on physics. Physics requires testable theories, otherwise it is only an exercise in idle speculation. Approach this book in that way, and you'll be satisfied. My recommendation: If you are amazed by the possibilities of time travel that are allowed by the physics in this book, read it again a little more carefully, remember that "you" are not a subatomic particle, and move on to material less speculative and actually rooted in science.

    Good for this type of content
  

*by T***. on Reviewed in the United States 🇺🇸 on June 26, 2006*

I searched extensively for a book that would explain current theories of time and the implications thereof that could be understood by a non-mathematical mind and one not trained in physics, and it was extraordinarily difficult.  I ended up choosing this book, which is probably as close as one will get to what I was hoping for.  The first and last chapters are actually the most accessible and interesting, the first being an overview of many fictional accounts of time travel (both movies and books) and the last a treatise on future prediction and probability, which I found most interesting and consoling.  The chapters inbetween were the denser material in which the author discusses whether or not time travel to the past or the future could work and, inevitably, it deals with the theory of relativity, wormholes, black holes, etc. and how all that would function, all of which is confusing for a layperson like me.  Nevertheless, this is, as I mentioned, the closest thing to a non-scientific explanation of what are at base purely mathematical constructs.  It does get one thinking philosophically about what "time" is and about time travel in general.  For example, if one can travel to the future, doesn't that imply that the future already "exists" as a "place" which one can visit? Mindbending reading and worth it for that reason alone.
