PAUL DAVIES

If you want to make your way to the past, then your best bet is to find a black hole conveniently equipped with a traversable wormhole, If the future is more your style, then get on a spaceship that travels just under the speed of light. With a tongue-in-cheek approach, renowned astrophysicist and science popularizer Davies shows how "a limited form of time travel is certainly plausible." Through lots of illustrations and straightforward text, he illustrates just how time-traveling contraptions would be built and what scientific principles would fuel them. Originally published in hardcover in 2001. Penguin, 2003, 131 p., b&w illus., paperback, $12.00.
