  Is time travel possible? According to internationally acclaimed physicist and science writer Paul Davies, the answer is definitely yes. But if we can travel in time, surely we can glimpse the future and act to change it? Or alter the past, creating all sorts of bizarre paradoxes? This hugely entertaining brain-twisting book reveals how it might be done. With his remarkable gift for easy explanation, Paul Davies shows how to use gravity to visit the future and how to warp space to reach the past; and, in a tour de force , how to build a time machine from a traversable wormhole. This is the ultimate time traveller's companion. Paul Davies expertly and effortlessly explains the mind-boggling physics that makes time travel possible, and more importantly shows how we can make sense of this very possiblity. Might the inconceivable be achievable? Can we break the last cosmic taboo?

  Inspired at an impressionable age by the work of science fiction writers H.G.Wells and Arthur C Clarke, Paul Davies has thought long and hard about ways to travel in time. Here, the best-selling popular science writer finally reveals how it can be done - without breaking the laws of physics and without causing any earth-shattering paradoxes. Since time is money, time travel is a costly business. But with the help of a handy black hole, or better a wormhole, and a bit of luck, Davies' guide illustrates how this new mode of travel could yet be a viable option.
