Time To Go

There are various arguments for the metaphysical impossibility of time travel. Is it impossible because objects could then be in two places at once? Or is it impossible because some objects could bring about their own existence? In this book, Nikk Effingham contends that no such argument is sound and that time travel is metaphysically possible. His main focus is on the Grandfather Paradox: the position that time travel is impossible because someone could not go back in time and kill their own grandfather before he met their grandmother. In such a case, Effingham argues that the time traveller would have the ability to do the impossible (so they could kill their grandfather) even though those impossibilities will never come about (so they won't kill their grandfather). He then explores the ramifications of this view, discussing issues in probability and decision theory. The book ends by laying out the dangers of time travel and why, even though no time machines currently exist, we should pay extra special care ensuring that nothing, no matter how small or microscopic, ever travels in time.

This thought-provoking collection not only takes us into the past and the future, but also explores what might happen if we attempt to manipulate time to our own advantage. These stories show what happen once you start to meddle with time and the paradoxes that might arise. It also raises questions about whether we understand time, and how we perceive it. Once we move outside the present day, can we ever return or do we move into an alternate world? What happens if our meddling with Nature leads to time flowing backwards, or slowing down or stopping all together? Or if we get trapped in a constant loop from which we can never escape. Is the past and future immutable or will we ever be able to escape the inevitable? These are just some of the questions that are raised in these challenging, exciting and sometimes amusing stories by Kage Baker, Simon Clark, Fritz Leiber, Christopher Priest, Kristine Kathryn Rusch, Robert Silverberg, Michael Swanwick, John Varley and many others.

Time travel romance is not the same thing as sci-fi romance, though some stories may be set in an imagined future; it is romantic fiction set in various different eras, usually from around the sixteenth to the eighteenth centuries.

The Mammoth Book of Time Travel Romance contains 25 stories of adventure and love; settings include medieval Scotland, sixteenth-century England, the nineteenth-century 'Wild West'. Some stories are set in the present and a few in the future. Stories include an Elizabethan nobleman whisked into the present day, a troubled young woman who lands in the sixteenth century able to break a curse of lost love.

In recent years numerous films, television series, comic books, graphic novels and video games have featured time travel narratives, with characters jumping backward, forward and laterally through time. No rules govern time travel in these stories. Some characters move by machine, some by magic, others by unexplained means. Sometime travelers can alter the timeline, while others are prevented from causing temporal aberrations. The fluid forms of imagined time travel have fascinated audiences and prompted debate since at least the 19th century. What is behind our fascination with time travel? What does it mean to be out of one's own era? How do different media tell these stories and what does this reveal about the media's relationship to time? This collection of new essays--the first to address time travel across a range of media--answers these questions by locating time travel narratives within their cultural, historical and philosophical contexts. Texts discussed include Doctor Who, The Terminator, The Georgian House, Save the Date, Back to the Future, Inception, Source Code and others.
