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.
