This book contains a broad overview of time travel in science fiction, along with a detailed examination of the philosophical implications of time travel. The emphasis of this book is now on the philosophical and on science fiction, rather than on physics, as in the author's earlier books on the subject. In that spirit there are, for example, no Tech Notes filled with algebra, integrals, and differential equations, as there are in the first and second editions of TIME MACHINES. Writing about time travel is, today, a respectable business. It hasn’t always been so. After all, time travel, prima facie, appears to violate a fundamental law of nature; every effect has a cause, with the cause occurring before the effect. Time travel to the past, however, seems to allow, indeed to demand, backwards causation, with an effect (the time traveler emerging into the past as he exits from his time machine) occurring before its cause (the time traveler pushing the start button on his machine’s control panel to start his trip backward through time). Time Machine Tales includes new discussions of the advances by physicists and philosophers that have appeared since the publication of TIME MACHINES in 1999, examples of which are the chapters on time travel paradoxes. Those chapters have been brought up-to-date with the latest philosophical thinking on the paradoxes.

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.

Time travel is metaphysically possible. Nikk Effingham contends that arguments for the impossibility of time travel are not sound. Focusing mainly on the Grandfather Paradox, Effingham explores the ramifications of taking this view, discusses issues in probability and decision theory, and considers the potential dangers of travelling in time.

In this twisting time-travel thriller, a woman faints on the eve of her wedding—and awakens at the turn of the century in her grandmother’s body . . . The night before she is supposed to get married, Shay Garrett has no idea that a glimpse into her grandmother’s antique Chinese mirror will completely transform her seemingly ordinary life. But after a bizarre blackout, she wakes up to find herself in the same house—but in the year 1900. Even stranger, she realizes she is now living in the body of her grandmother, Brandy McCabe, as a young woman. Meanwhile, Brandy, having looked into the same mirror, awakens in Shay’s body in the present day—and discovers herself pregnant. As Rachael—the woman who links these two generations, mother to one and daughter to another—weaves back and forth between two time periods, this imaginative thriller explores questions of family, identity, and love. Courageous, compassionate Shay finds herself fighting against the confines of a society still decades away from women’s liberation, while Brandy struggles to adapt to the modern world she has suddenly been thrust into. The truth behind this inexplicable turn of events is more complex than either woman can imagine—and The Mirror is a tribute to the triumph of the female spirit, even in the face of seemingly insurmountable obstacles. “What happens will surprise you. In the meantime, settle down for a good read.” —The Denver Post

For the past 20 years causality violations and superluminal motion have been the object of intensive study as physical and geometrical phenomena. This book compiles the results of its author and also reviews other work in the field. In particular, the following popular questions are addressed: Is causality protected by quantum divergence at the relevant Cauchy horizon? How much "exotic matter" would it take to create a time machine or a warp drive? What is the difference between a "discovered" time machine and a created one? Why does a time traveler fail to kill their grandfather? How should we define the speed of gravity and what is its magnitude?

Folsom's Planet - An Alien land yet so familiar. If the mission were a success, Folsom's planet would bear his name for eternity. The barbarians would be civilized; the planet would join the Federation; the Federation's integrity would be preserved. But Hans Folsom had to be on guard. The aliens were intractable, his crew possibly traitorous. There was an incident during the voyage he couldn't quite remember. And a prophetic runic stone. Had ancient spacemen visited here in the past? Did that explain the strange religions, the ancient ruins, the mysterious runic stone?

The story of physicists' quest to answer a mind-boggling question: How can we travel through time? Since H. G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics. Some images in the ebook are not displayed owing to permissions issues.
