How to Build a Time Machine - Tapa dura

Inspired at an impressionable age by the work of science fiction writers such as H.G.Wells and Arthur C Clarke, Paul Davies has thought long and hard about possible ways to travel in time in much the same way that you can travel in space. In HOW TO BUILD A TIME MACHINE 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 withthe help of a handy black hole, or better a wormhole, and a bit of luck, Davies's guide illustrates how this new mode of travel could yet be a viable option.

Paul Davies is an internationally acclaimed physicist, writer and broadcaster, now based in South Australia. He works in the fields of cosmology, gravitation, and quantum field theory, with particular emphasis on black holes and the origin of the universe. He is the author of some twenty award-winning books, including The Mind of God and The Fifth Miracle: The Search for the Origin of Life.
