In Search of the Edge of Time: Black Holes, White Holes, Wormholes by Gribbin, John. paperback edition. ISBN: 9780140248142.

Time travel has been a common feature in popular science fiction, but with todays understanding of black holes, it could possibly be a reality. Many astrophysicists believe black holes can function as tunnels leading to other times and other places and that they contain the key to the Big Bang. In this enthralling book John Gribbin lucidly explains such theories and guides us through a still emerging cosmos of neutron and X ray stars, white dwarfs, quasars, and pulsars. "Fascinating." --Hans Christian von Beyer, The New York Times Book Review
