Ten Short Lessons

During times like these, who hasn't daydreamed about traveling forward or backward in time?

In Time Travel: Ten Short Lessons, popular-science master Brian Clegg gives a grand tour of the essential lessons in this game-changing area of physics, from the imagination of novelists to current research.

Einstein's special theory of relativity told us that time travel to the future was possible, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backward, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with paradoxical twists in time—and could quantum physics hold the answer? Packed full of easy-to-understand diagrams and fact boxes, these ten lessons cover all the basics, as well as the latest understanding and developments, to enlighten the nonscientist.
