Time travel is the most exciting technological development looming in our future. It is also the most misunderstood. Alleged paradoxes as well as strong cultural taboos have kept the subject mostly outside the realm of serious thinking and theorizing, and science-fiction writers have peddled numerous myths and misconceptions. It's such a knotty subject that even physicists have stumbled and gone down blind alleys. This book, by the author of the acclaimed Time Loops, attempts to clear up the misconceptions and bust the myths. Topics include: Time paradoxes Technologies for predicting the future and communicating across time Wormholes and time machines The possibility that the UFO phenomenon is related to time travel Navigating in time The possible role of time travel in the creation of the universe Meeting your younger or older self across time Wargo helps readers imagine a future in which humans are not confined to their present historical moment but actually explore the fourth dimension, sowing seeds in the past for a better tomorrow. Eventually, our species may even help create the universe-our own universe-by going back to its Beginning.
