Review
"In ‘How to Build a Time Machine’ we start each chapter with an affirmation; ‘Yes, time travel is possible …’. There’s clarification, ‘ifs’, often detailed historic references; consequences; and then the practicalities – at which point you might have the feeling that it’s not possible after all. But then there’s the ‘Or is it?’, and one cannot but take the bait and turn the page (loop). To name but a few, what does the following have to do with time-travel?: near-light speed travel; an infinitely long cylinder built from dust - or a less ambitious one (!) built from Neutron stars; Wormholes; Paradoxes; Black/White Holes; Antimatter; Dark Energy…? If you’re like me when presented with such a list - appetite whet to the point of drooling - this is a book written with you in mind! One last and very important point: Clegg is both a writer and a Physicist; and it’s as a writer – one who is able to communicate physics to the non-specialist – and that makes this book so very enjoyable. The hard stuff is there; between the lines; but we’re not asked to deal with it – Clegg leads us through, in his own imitable style! There are just two equations: Einstein’s E=MC2 (of course!), and Maxwell’s – the latter because they’re so “beautifully spare and simple looking”. Perfect." - Dr. Peet Morris of Oxford University

Time travel: Close, but no cigar!
By Alan F. Sewell
Being an old sci-fi buff going back to the 1960s, plus having a rudimentary education in physics, I've read tons of books about time travel. Everything from Isaac Asimov and George Gamow in the 60's to Michio Kaku and Stephen Hawking in the 2000s. Time travel has become as much a staple of speculation as space aliens. The question is whether Brian Clegg's HOW TO BUILD A TIME MACHINE adds anything to the discussion, or is it just a smarmy rehash of time-worn (no pun intended) theories.
The answer is, "Yes, it does indeed significantly add to the discussion of time travel theory." Despite a lifetime of reading about relativity and quantum mechanics I gleaned some interesting insights that made this book well worth the read:
1. Clegg explains how the discussion about the nature of time has a long history, starting with Plato, then going through St. Augustine and Galileo, and then on down to contemporary physicists. Most of the ideas that modern physicists argue about, such as whether time is a dimension or merely a measure of change, whether the past is immutable, or whether human beings have free will so as to affect unfolding events, have been debated for centuries from the scientific, philosophical, and theological angles.
2. He then opens a most entertaining window into the personalities who gave such great drama to the "golden age of physics" encompassing Einstein's Theory of Relativity and Niels Bohr's discoveries of Quantum Mechanics. Einstein was a physicist who craved order. He thought that in his Theory of Relativity he had found the beautifully designed blueprint of the universe. Then along comes the Quantum Mechanics crowd with their ideas that subatomic particles are merely probabilities that have no reality until they are measured, of particles spontaneously dematerializing and rematerializing, and of "quantum entanglement" whereby particles on the opposite sides of the universe may "communicate" with each other instantaneously when one of them is measured. Clegg explains how Einstein rebelled with his whole intellect at this theory of quantum disorder.
3. Clegg then explains how the most bizarre effects of Quantum Physics appear in everyday life, such as when a beam of light hits a plane of glass and each photon must "decide" whether to pass through the glass or be reflected back as a mirror image. Because of quantum entanglement the photons appear to "know" the thickness of the glass before they actually pass through it, and, after determining the thickness of the glass, a certain percentage of the photons "decide" to bounce off the front end of the pane.
4. He also gives interesting biographical sketches of the leading minds of physics including Einstein, Niels Bohr, Max Planck, and Nicola Tesla, who seems to have become insane after his experiments with powerful electromagnetic waves deranged his brain. There are also the discoveries of the less well-known people like Alain Aspect who devised an ingenious experiment to prove beyond doubt the effects of quantum mechanics. I was also introduced to the work of Ronald Mallett, who seems to be on the current frontier of work in trying to accomplish time travel by warping space through rapid rotation.
So, is time travel possible --- the "fun kind" that is, when you could go back in time and mess around with the past or wing your way into the future to read the winning lottery numbers then come back to the present and place the winning bet? Conventional wisdom, of course, is that this kind of time travel that upsets causality is not allowable in Einstein's Relativistic universe. The architecture of Einstein's Spacetime sets a minimum and maximum speed for the passage of time (time passes at maximum speed when an object is at rest but slows to a crawl when an object is accelerated to nearlight speed) but time can't flow backward.
However, the random nature of Quantum Mechanics opens up a whole 'nother can of worms. Clegg explains that we now know that photons and certain other particles most certainly do travel faster than light. It happens all the time. Photons can dematerialize and rematerialize on the other side of an impenetrable barrier, thus traversing gaps in physical space in zero time. Clegg gives the stunning example of how a Professor Gunter Nimtz has made a recording of Mozart's Fortieth Symphony, the recording consisting entirely of microwaved photons that have gapped through space, dematerializing before encountering an impenetrable barrier and rematerializing on the other side.
Is it possible, then, to harness Quantum Mechanics so as to dematerialize an object and rematerialize it instantaneously at a different location, thereby by-passing Spacetime, like Star Trek's transporter beam? Is it possible to use quantum entanglement to transmit information instantaneously between distant objects? Is it possible to use engineering on a stellar scale to create Spacetime-warping "wormholes" that would allow us to jump from any point in Spacetime to any other point, going backward or forward to any desired point in the four dimensions of space and time?
Clegg takes us tantalizingly close to the answer we want to hear, which is "Yes, we WILL be able to discover a way to run around in the past and the future, then come back to the present." Alas, we only come CLOSE to being able to do this. The very randomness that goes to the heart of Quantum Mechanics in the end defeats any attempt to apply it in a predictable way to go from point "X,Y,Z,T" ("t" representing time) to point "X1,Y1,Z1,T1."
What Clegg does leave us with is evidence that the bizarre nature of Quantum Mechanics surrounds us. He explains how we see evidence of it in every day occurrences such as the double-image in a window pane when photons "decide" whether to be reflected from the glass or to pass through it. Alas, we don't have a way of harnessing the random nature of Quantum Mechanics to make it do the useful work of travelling through space and time (the analogy of perpetual motion machines comes to mind) but its effects are nonetheless logic-defying. Within its subatomic frame of tiny distances and time frames, Quantum Mechanics makes a mockery of the beautifully structured blueprint of Einstein's Relativity that rules the universe at a macro level.
Because Clegg makes many obscure points in Relativity and Quantum Mechanics clear, because he covers a wide spectrum from physics to the personalities of the scientists who discovered its laws, because he gives the clearest explanation I've yet heard of the current state of knowledge of time travel, and because he writes with delightful clarity that makes his ideas easy to understand, I rate this book five stars. It's a great read even if you've already read everybody else's take on the subject.

The Real Science of Time Travel
By D. Wayne Dworsky
Here’s the book the science reading community’s been waiting for, How to Build a time Machine. Ever since H. G. Wells’ famous book, The Time Machine, made its appearance in 1895, the science community’s been grappling with the possibility of time travel. Even the celebrated Albert Einstein announced to the world early in his career, as a theoretical physicist, that time travel was theoretically possible.
Consistent with his brilliant observations of other great minds and their inquisitive nature, Brian Clegg expresses his interpretations of Einstein’s space-time and H. G. Wells’ speculations of moving through time. He captures the prospect of time travel in exquisite detail with comparable tenacity as those great thinkers. The resulting vision will tantalize your instinct.
Of course, one of the enormous problems of time travel involves running into paradoxes. When we start to consider moving backwards or forward through time, along with the fact that we already exist in another time frame, problems arise. In many situations they simply cannot be avoided. If you travel back in time and accidentally kill your mother, does that mean you were never born and therefore could not have traveled back in time in the first place? Or if we move into the future and do something we contemplate in time past, does that mean we must do what we contemplated from the past? Thinking about the way these paradoxes contradict common sense tends to make understanding such a simple idea very confusing. But the author does a marvelous job at ironing it all out.
Brian Clegg has distinguished himself as an accomplished visionary in theoretical science, having written extensively in several renowned publications. In the present work, he proposes an idea that others might shun, but takes on the task with vigor and purpose, making reading about new avenues in science worth exploring.

It's a nice change for a non-fiction book to not get bogged ...
By Paul L.
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 might take to make each of these various concepts possible. It's a nice change for a non-fiction book to not get bogged down in the math of how this happens, but it's the theory that makes this enjoyable. Granted the theory behind this requires a bit of an understanding of modern day astronomy which without the general layperson would be lost. Also it's not hard to get somewhat lost in the chapter dealing w/ paradoxes which are perhaps the most confusing aspect of time travel in general. Overall, Clegg offers a book that is full of possibilities & an ending 2 paragraphs that state pretty much what we now know in that time travel is real & is a possibility. Just when that will happen only time will truly tell.
