    1. For a book about the wonders of time travel, this one isn't very enthusiastic. The science-history is interesting enough, although if that is what you're after I recommend A Brief History Of Time and The Physics of the Impossible as the best bits here are already attributed to Hawking and Kaku. The trouble with pop science books like this--and it isn't Clegg's fault at all--is that I'm a fan of the genre. I already know about Young's double slit experiment, relativistic time at speeds approachin [...]

    2. I am a science fiction writer that has written on wormholes and time travel. So I'm alwasys on the lookout for the the lastest research on time travel theory. That is why Mr. Clegg's book was a great surprise for me and and an easy to read work on the basics or the reltavistic principles of the features involved with the traveling through spacetime.His chapter on the story of Ronald Mallett and his research was an incredible chapter on the newest research on this exiting subject.I get a lot of q [...]

    3. A lot of it is really technical, but very informative which leads me to wonder why Sheldon and Leonard (Big Bang Theory) are always waiting for time traveling selves to walk through the door? Being physicists they should know the rules about traveling to the past. Can't say much more without giving the plot away!

    4. It seemed to me he was struggling to fill the pages. He repeats himself over and over again. Found it dull, often annoying. Nothing in there I hadn't already read somewhere else where it was presented in a more interesting way.

    5. This popular science book is trying to do three different things at the same time: describe some basic physics concepts, such as electromagnetism, special relativity, and general relativity, discuss how these theories treat the possibility of time travel, and narrate anecdotes about physicists associated with these theories. As it's hard to achieve all three goals at the same time, the book lacks depth.

    6. A useful summary of how time has been conceived, measured, and studied going back to Greek philosophers and extending up to present day experiments and speculation. I liked the tone of this book and the author’s presentation.

    7. I considered giving this book four or five stars because I got a lot out of it and because I think Brian Clegg is a terrific science writer. But I just can't get past the problem of the title. This book will not help you to make a time machine. Just the opposite really. Although he never says so, the result of reading his book is clearly that given the laws of physics, time travel is impossible. This is clearly implied in his examples, for instance when he suggests you could time travel "if you [...]

    8. Before beginning my review of this book I want to make it perfectly clear I have very little prior knowledge of quantum mechanics and physics that I used to inform my reading and that was my motivation to pick up Brian Clegg’s book. I love physics but hate math, which is a bad combination in the academic/practical world of physics. I do have the background of some college level physics, and that was enough for me to understand the concepts the way Clegg explains them in his book. Unlike what t [...]

    9. No self-respecting science fiction writer would try to write without actually reading some science, and this is more ammunition for my speculation gun. Brian Clegg holds a physics degree from Cambridge University, and is the author of other popular books on physics such as Before the Big Bang and Armageddon Science. He does a good job of writing about some pretty heady stuff (quantum theory) without losing most of his readers. In contrast to most physicists, he also had the ability to communicat [...]

    10. Time travel? That would free up my schedule for reading and give me the opportunity to get a better mortgage rate and fix that pesky arrest record. Though not a how-to, this absorbing title enjoyably discusses scientific topics ranging from the zeroth law of thermodynamics to the evolution of the calendar‚ all in relation to the concept of time. Clegg points out that memory is a one-way time machine‚ though I was hoping for a phone-booth-esque machine with buttons and levers. Reading his sum [...]

    11. Time travel is a concept that is today more science fact than science fiction, but the key to understanding how this could become reality is the main question that Brian Clegg addresses in this rather interesting book. Clegg takes us on a journey that takes us from the very basic question of what is time all the way through the question of paradoxes. In the journey he examines the feasibility of time travel & the energy as well as physics behind the concept. He also describes just what it mi [...]

    12. As a science fiction author I found this book an interesting read on the physics that can make time travel possible. It re-confirmed in my mind that the most likely means will be available in the distant future once there are starships that can make extended voyages at close to the speed of light, thus creating the time dilation Einstein's Theory of Relativity predicts. That would take the star traveler on a one-way trip into the future.Other theoretical means for time travel such as passing thr [...]

    13. After reading Stephen King's "1963", reading about book about whether or not time travel is real seemed to make sense. Clegg reviews the mysteries of quantum mechanics and historic experiments, even science fiction, that all touch on time travel. While the quantum physics gets tedious and hard to follow - even though Clegg does his best to keep things at a lay level - the reality that comes through is that time travel is probably not possible. Clegg remains optimistic - look how far technology h [...]

    14. Overview of theoretically valid time travel methods. I know this is a pop science book, so I wasn't expecting anything rigorous, but the author often left gaping holes in his explanations of possible time travel methods/devices. Background on relevant scientists and potential paradoxes was interesting, but the actual descriptions of how time travel theoretically would work left me disappointed. Granted, it's quantum mechanics, inherently difficult to explain, but if you're going to write a book [...]

    15. Before I read this understandable book, I thought a working time machine, or time travel of any sort, was impossible, at least for the next 500 years. But this book not only explains the difficulties we'll have to overcome, but how we are already taking care of those difficulties. Best of all, Brian Clegg explains how in an easy to understand manner, a hard writing style to come by in time travel books. Clegg doesn't stop at the technological and mathematical breakthroughs we'll need, however. M [...]

    16. Clegg surveys historical and current theories of time travel, often using classics of science fiction, such as “Star Trek” and “Doctor Who” as examples, and concludes that although nothing known in current physics would prevent time travel, in practice the forces and conditions that would allow it to happen are beyond our current technical capabilities since they would involving the manipulation of masses denser than stars, and equally immense quantities of energy. This is good survey of [...]

    17. It wasn’t what I was expecting, but it was fairly interesting.He does a very good job covering the math and science behind the theoretical ways time travel could happen, but he also explores the people throughout the history of math and science who have tackled this problem, and not only explains their words and theories to the average lay person, he makes them all come alive and shows how human these people, despite a reputation for being dry and distant.

    18. Read the whole book, and I still don't know how to build a time machine.Joking aside, this is an introduction to topics such as the measurement and flow of time, relativity, entanglement, wormholes, and causality paradox. It takes a while to address the possibility of time travel. Not too surprisingly, the answer is "Who knows?"

    19. This book addresses the real physics of time travel. Is it possible? Yes. Is it practical? Not any time soon. I am not a physics scholar and some of the science here is over my head, but I appreciate being exposed to the physics even if I don't understand it well. The history was interesting and even charming sometimes. The author's writing style is approachable and I enjoyed it.

    20. This was sent to me as a gift/ a joke really, by my podcast partner - Damien, because he felt I should "build" a time machine for my Future Girls series. After wading through this book I still think that a little magic in the time travel cannon is the best way for an artist to approach the problem. But I appreciated the thought.

    21. This book was an easy read with the science clearly explained and next to no math equations to figure out. The author traced the history of theories of light, how time travel would have to work and where we are along the journey of what it would take for time travel. Science fiction is much more optimistic.

    22. Very well written introduction to some of the more 'interesting' applications of modern physics. Don't panic, no equations. If you have ever wondered how possible time travel may be, without getting a degree in physics, this is the book for you.

    23. WAY better than ' About Time ' by Frank ( which was closer to ' Waste of Time ' ) Akward in parts but overall very good

    24. Great book. Goes in depth about the concepts without using math. Clegg does a great job of explaining things simply, yet not leaving you to feel like he's left parts out.
