The Science Of Time Travel

The idea of time travel is one that never gets old. It has enthralled the imaginative, the serious, and the scientific for centuries. Your readers will learn the science behind the fantasy of time travel, the theories behind such an ability, and the inventions that are trying to get us to the past, and beyond.

This book explores the idea of time travel from the first account in English literature to the latest theories of physicists such as Kip Thorne and Igor Novikov. This very readable work covers a variety of topics including: the history of time travel in fiction; the fundamental scientific concepts of time, spacetime, and the fourth dimension; the speculations of Einstein, Richard Feynman, Kurt Goedel, and others; time travel paradoxes, and much more.

A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson). It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur. Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American, Time, and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” (Booklist). “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.” —Publishers Weekly

From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favorite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That’s just what Paul J. Nahin’s guide provides. An engineer, physicist, and published science fiction writer, Nahin is uniquely qualified to explain the ins and outs of how to spin such complex theories as worm holes, singularity, and relativity into scientifically sound fiction. First published in 1997, this fast-paced book discusses the common and not-so-common time-travel devices science fiction writers have used over the years, assesses which would theoretically work and which would not, and provides scientific insight inventive authors can use to find their own way forward or backward in time. From hyperspace and faster-than-light travel to causal loops and the uncertainty principle and beyond, Nahin’s equation-free romp across time will help writers send their characters to the past or future in an entertaining, logical, and scientific way. If you ever wanted to set up the latest and greatest grandfather paradox—or just wanted to know if the time-bending events in the latest pulp you read could ever happen—then this book is for you.

Its' Really About Time provides a clear and complete explanation of why it will someday be possible to travel years, decades or even centuries in the future, a direct consequence of Einstein's Special Theory of Relativity. The book is aimed at intellectually curious people and requires no previous science or mathematics training.

Best Books of 2016 BOSTON GLOBE * THE ATLANTIC From the acclaimed bestselling author of The Information and Chaos comes this enthralling history of time travel—a concept that has preoccupied physicists and storytellers over the course of the last century. James Gleick delivers a mind-bending exploration of time travel—from its origins in literature and science to its influence on our understanding of time itself. Gleick vividly explores physics, technology, philosophy, and art as each relates to time travel and tells the story of the concept's cultural evolutions—from H.G. Wells to Doctor Who, from Proust to Woody Allen. He takes a close look at the porous boundary between science fiction and modern physics, and, finally, delves into what it all means in our own moment in time—the world of the instantaneous, with its all-consuming present and vanishing future.

Fact or fiction? Real or impossible? Movement through time explored, explained and examined! Albert Einstein's theory of relativity postulates, and scientists have proven, that the faster you travel, the slower time moves. Clocks on airplanes, satellites and rockets are slower than clocks on Earth, and time travel is indeed real. Can time machines, time-tunnel wormholes or tales of fictional time-traveling heroes be so far-fetched? Covering the history of time travel in both reality and fiction, Time Travel: The Science and Science-Fiction investigates the long history, myths, science and stories of movement from the present to the past and into the future. Timely in its telling, Time Travel chronicles more than 30 instances, accounts, stories and famous examples of time slips, such as ... The theory of relativity showing the link between time and space H.G. Wells' epic novel of 1895: The Time Machine British physicist Stephen Hawking's famous paradoxes surrounding time travel Charlton Heston's character Taylor in the Planet of the Apes discovering that he is home, 2,000 years in the future Wormholes, the shortcuts through both space and time And many more! The idea of time travel fascinates because it offers the possibility, however remote, of revisiting and recapturing moments from our youth. And if travelers of the future have secretly visited us--well, that proves that our future is secure. Stories of time travel abound in books and film, and it's been a source of endless fascination--and speculation--surrounding UFO sightings and conspiracy theories. This richly researched reference ripples with fascinating information. With more than 120 photos and graphics, this tome is nicely illustrated. Time Travel also includes a helpful bibliography and an extensive index, adding to its usefulness. Time will fly by as you ponder the possibilities. Don't hesitate. There's no time like the present. Get your copy today. The future is waiting!

"Astonishing."—The New York Times "A fascinating meditation on the many ways traveling through time can change a person." —HelloGiggles "This genre-bending, time-bending debut will appeal to fans of Doctor Who, dystopian fiction, and life's great joy: friend groups."—Refinery29 Perfect for fans of Naomi Alderman's The Power and Margot Lee Shetterly’s Hidden Figures comes The Psychology of Time Travel, a mind-bending, time-travel debut. In 1967, four female scientists worked together to build the world’s first time machine. But just as they are about to debut their creation, one of them suffers a breakdown, putting the whole project—and future of time travel—in jeopardy. To protect their invention, one member is exiled from the team—erasing her contributions from history. Fifty years later, time travel is a big business. Twenty-something Ruby Rebello knows her beloved grandmother, Granny Bee, was one of the pioneers, though no one will tell her more. But when Bee receives a mysterious newspaper clipping from the future reporting the murder of an unidentified woman, Ruby becomes obsessed: could it be Bee? Who would want her dead? And most importantly of all: can her murder be stopped? Traversing the decades and told from alternating perspectives, The Psychology of Time Travel introduces a fabulous new voice in fiction and a new must-read for fans of speculative fiction and women’s fiction alike.
