Paradoxes Of Time Travel

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.

Featuring numerous updates and enhancements, Science Fiction and Philosophy, 2nd Edition, presents a collection of readings that utilize concepts developed from science fiction to explore a variety of classic and contemporary philosophical issues. Uses science fiction to address a series of classic and contemporary philosophical issues, including many raised by recent scientific developments Explores questions relating to transhumanism, brain enhancement, time travel, the nature of the self, and the ethics of artificial intelligence Features numerous updates to the popular and highly acclaimed first edition, including new chapters addressing the cutting-edge topic of the technological singularity Draws on a broad range of science fiction’s more familiar novels, films, and TV series, including I, Robot, The Hunger Games, The Matrix, Star Trek, Blade Runner, and Brave New World Provides a gateway into classic philosophical puzzles and topics informed by the latest technology

Ryan Wasserman explores a range of fascinating puzzles raised by the possibility of time travel, with entertaining examples from physics, science fiction, and popular culture, and he draws out their implications for our understanding of time, tense, freedom, fatalism, causation, counterfactuals, laws of nature, persistence, change, and mereology.

Is time travel just a confusing plot device deployed by science fiction authors and Hollywood filmmakers to amaze and amuse? Or might empirical data prompt a scientific hypothesis of time travel? Structured on a fascinating dialogue involving a distinguished physicist, Dr. Rufus, a physics graduate student and a computer scientist this book probes an experimentally supported hypothesis of backwards time travel – and in so doing addresses key metaphysical issues, such as causation, identity over time and free will. The setting is the Jefferson National Laboratory during a period of five days in 2010. Dr. Rufus’s experimental search for the psi-lepton and the resulting intractable data spurs the discussion on time travel. She and her two colleagues are pushed by their observations to address the grandfather paradox and other puzzles about backwards causation, with attention also given to causal loops, multi-dimensional time, and the prospect that only the present exists. Sensible solutions to the main puzzles emerge, ultimately advancing the case for time travel really being possible. A Time Travel Dialogue addresses the possibility of time travel, approaching familiar paradoxes in a rigorous, engaging, and fun manner. It follows in the long philosophical tradition of using dialogue to present philosophical ideas and arguments, but is ground breaking in its use of the dialogue format to introduce readers to the metaphysics of time travel, and is also distinctive in its use of lab results to drive philosophical analysis. The discussion of data that might decide whether time is one-dimensional (one timeline) or multi-dimensional (branching time) is especially novel.

In 2554, the World is Coming to its End, unless an impossible mission through 600 years of time travel succeeds. Maternal instinct knows no boundaries, including the nano-neural-net intravenously installed in Dannia Weston’s mind to repress her identity, allowing her to perform a mission 300 years before her time. Transported to the year 1954, Dannia becomes a woman with a mid-twentieth century persona, college educated with an aptitude for mechanical invention. Due to her work during the war, she is employed by the U.S. government on a secret project. But what no one knows—including Dannia or those who sent her back to tinker with the mechanical past to reduce future pollution—is what might happen should she become emotionally involved in 1954. The 2254 science team programmed the nano-net to prevent the possibility of pregnancy, but each person reacts to strong emotional stimuli differently, and using birth control not available in 1954 is out of the question. When Dannia falls in love with Peter Hersh and becomes pregnant, her hormones erode a small section of the nano-chained network that stabilizes her new identity, triggering a mild memory rebirth...and threatening her mission and the fate of the world.

The Time Machine by H. G. Wells is a science fiction classic, which lends itself well to visualization. This version, illustrated by Yoann Laurent-Rouault, an illustrator master who graduated from the Beaux-Arts, and published in the international literary collection Memoria Books, is a reference on the time travel theme. Wells transports us in the year 802 701, in a society made up of the “Elois”, who live peacefully in a kind of big Garden of Eden, eating fruits and sleeping high up, while underground lives another species, also descending from men, the “Morlocks”, who do not stand the light anymore, living in the dark for too long now. At night, they return to the surface, going back up by the wells, in order to kidnap some Elois that they eat ; these last became livestock unknowingly. In The Time Machine, made into a movie several times, the last of them in 2002 by Simon Wells, the great-grandson of H. G. Wells, time is both a pretext to move the class struggle and warn... and also, in a way, a full character, who fascinates, arbitrates, transcends... The illustrations come to reinforce the time travel and provide a new experience to the reader.

This “stimulating contribution to literary theory” reveals the deeply philosophical concerns and developments behind popular time travel sci-fi (London Review of Books). In Time Travel, literary theorist David Wittenberg argues that time travel fiction is not mere escapism, but a narrative “laboratory” where theoretical questions about storytelling—and, by extension, about the philosophy of temporality, history, and subjectivity—are presented in story form. Drawing on physics, philosophy, narrative theory, psychoanalysis, and film theory, Wittenberg links innovations in time travel fiction to specific shifts in the popularization of science, from nineteenth-century evolutionary biology to twentieth-century quantum physics and more recent “multiverse” cosmologies. Wittenberg shows how popular awareness of new science led to surprising innovations in the literary “time machine,” which evolved from a vehicle used for sociopolitical commentary into a psychological device capable of exploring the temporal structure and significance of subjects, viewpoints, and historical events. Time Travel draws on classic works of science fiction by H. G. Wells, Edward Bellamy, Robert Heinlein, Samuel Delany, and Harlan Ellison, television shows such as “The Twilight Zone” and “Star Trek,” and other popular entertainments. These are read alongside theoretical work ranging from Einstein, Schrödinger, Stephen Hawking to Gérard Genette, David Lewis, and Gilles Deleuze. Wittenberg argues that even the most mainstream audiences of popular time travel fiction and cinema are vigorously engaged with many of the same questions about temporality, identity, and history that concern literary theorists, media and film scholars, and philosophers.

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.

Two events made September 1st a memorable day for Jesse Cullum. First, he lost a pair of Oakley sunglasses. Second, he saved the life of President Ulysses S. Grant. In the near future of Robert Charles Wilson's Last Year, the technology exists to open doorways into the past--but not our past, not exactly. Each "past" is effectively an alternate world, identical to ours but only up to the date on which we access it. And a given "past" can only be reached once. After a passageway is open, it's the only road to that particular past; once closed, it can't be reopened. A passageway has been opened to a version of late 19th-century Ohio. It's been in operation for most of a decade, but it's no secret, on either side of time. A small city has grown up around it to entertain visitors from our time, and many locals earn a good living catering to them. But like all such operations, it has a shelf life; as the "natives" become more sophisticated, their version of the "past" grows less attractive as a destination. Jesse Cullum is a native. And he knows the passageway will be closing soon. He's fallen in love with a woman from our time, and he means to follow her back--no matter whose secrets he has to expose in order to do it.
