Can you really change the past? And if so, is it dangerous to do so? Should you be worried about the so-called Grandfather Paradox? What about the Butterfly Effect? What do time travellers really need to know? All these questions and more are answered, with examples from popular movies. "M.J." is an avid writer and gamer, co-creator of Multiverser: The Game, and well known for his web site Temporal Anomalies in Popular Time Travel Movies; some of his writings have been translated into French and German. He can be found on Facebook and other social media platforms, and through MJYoung.net, the Christian Gamers Guild, and Patreon. If you've ever watched a time travel film and thought to yourself, "Hey, that's not how it would work!" then this book is for you. While most time travel stories will simply have a character say a few lines of technobabble to handwave away plot holes or logical gaps, in The Essential Guide to Time Travel, Mark Joseph Young explains the leading time travel theories in a logical concise way, then picks apart some of our most loved and cherished time travel films to show how they either make sense or don't (hint, they usually don't). But he doesn't stop there. Young uses the replacement theory to rationalize what had to have happened across multiple unseen timelines in order for what we see on screen to have happened. His analyses also plausibly solve paradoxes that the stories themselves create, thereby saving the universe! The knowledge contained in this book will make you enjoy the time travel genre in new, mind-blowing ways. You'll never just "watch" another time travel movie ever again.

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.

Presents the current understanding of the nature of time and space, and an approachable explanation of Einstein's theory of special relativity; then goes on to connect these to possible time travel along with the accompanying paradoxes involved.

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.
