Time Travel: A guide to Journeys in the Fourth Dimension

By John W. Macvey

Only a Hundred year ago space travel was the sheerest of fantasies.  No longer. Will time travel become a reality too? Will we find ourselves riding a time craft into the past  to witness Lincoln’s assassination and into the future to see if mankind survives? And will we manage to “side-step” into time, into another present, possibly to shake hands with ourselves in any on of a multitude of parallel universes? The prospects are intriguing, even mindboggling: and here a renowned astronomer, John W Macvey, put these possibilities and more before the examining lens of a scientific telescope.

The Author explains the types of time travel that are scientifically credible – from time diation (which occurs in space travel at near-light speeds) to the passage through black hole/white hole bridge, that singular cosmic phenomenon that may be the ultimate time warp, He also discusses the dilemmas imposed by logic: Could a traveler into the future observe the cause of his own death. and return to the point of departure to do something to avert the fate? Is the future immutable? is there only on future? Here is science fact at its best.

John W. Macvey, an internationally renowned writer on astronomy and astronautics, is a Fellow of the Royal Astronautics Society.  The owner of his own observatory, he specializes in observing variable stars. He is the author of many well-received books including Interstellar Travel (selected by Library Journal as one of the 100 best scientific books of its year), Space Weapons/Space War, Colonizing Other Worlds, and Many others.
