Time Travel and Warp Drives: A Scientific Guide to Shortcuts through Time and Space
“In recent years, a number of books have taken on real science that sounds like science fiction. Unfortunately, most are frothy concoctions that leave the serious reader unsatisfied. This is all the more reason to celebrate the arrival ofTime Travel and Warp Drives—a deeply informed, richly detailed yet immensely readable account of science at the frontiers, by two physicists who know the territory. For well over a decade Allen Everett and Thomas Roman have been charting the strange realms of negative energy, twisted spacetime, temporal paradoxes, and travel between universes. In a wonderfully written and especially timely account, they share with us what they’ve learned.Time Travel and Warp Drivesdeserves a place on the shelf between Greene’sThe Elegant Universeand Hawking’sA Brief History of Time.”(David Toomey, author of The New Time Travelers: A Journey to the Frontiers of Ph)“There have been plenty of light popularizations of the puzzling physics of time. This book stands out in its depth and range. Written by two who have done the calculations, followed the field, and thought about what it all means, it leads the reader through the byzantine labyrinths of current theory. I found it enlightening and fun to read. If you have time for one book in this field, let it be this one.”(Gregory Benford, author of Timescape)"I have been searching for years for a book like this. WithTime Travel and Warp Drives, Everett and Roman have written an illuminating exploration of the physics of time travel. What sets this book apart, however, is that the authors do not rely on analogies or metaphors. They actually explain the underlying science in a clear and accessible way. My search is over: this book is my new guide to a place stranger than science fiction--our universe."(Charles Yu, author of How to Live Safely in a Science Fictional Universe)“Einstein meets Captain Kirk in this improbable foray into the frontiers of theoretical physics, where readers survey the exciting possibilities for traveling through time and between galaxies. . . . Relying only minimally on technical jargon and formulas, the authors open to view the exciting conceptual prospects for designing a time machine capable of slipping backward through the centuries and of riding fast-than-light warp bubbles through the cosmos. . . . Armchair scientists share the thrill of peeking into the universe’s deepest secrets. Penetrating science illuminates humankind’s most audacious dreams."(Bookliststarred review)
