	As one of the foremost scientists in the field of time travel, Princeton astrophysicist Gott takes it upon himself to disseminate advice on building time machines. The construction of the vessel itself is rarely of concern here; it is the way it is used and the way that space-time (the dimensions of space and time that we collectively consider to be our universe) behaves around it that may eventually allow adventurers to break with the usual order of things. Believing that science fiction often spurs true scientific discovery, Gott explores numerous theatrical and literary concepts before moving on to current bona fide theories, pointing out the difficulties of each method. Some possibilities for leaving the present involve dismantling Jupiter, making use of "cosmic strings," taking a trip at near light-speeds far out into space then back and warping space-time itself. Einstein's theory of relativity, upon which all of the presented theories depend, is described in impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read. (May 21)Forecast: This book will appeal to anyone who has ever been fascinated by time travel, as well as those who many have considered such a thing. Liberally sprinkled diagrams will help readers who find this stunning array of craziness a lot to take in. Good handselling by booksellers will ensure the author's events in New York, Boston, Ann Arbor, Seattle and San Francisco are well attended, and word-of-mouth by readers of all stripes will boost sales beyond the initial push.
