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.

Welcome, intrepid temporal explorers, to the world's first and only field manual/survival guide to time travel!DON'T LEAVE THIS TIME PERIOD WITHOUT IT! Humans from H. G. Wells to Albert Einstein to Bill & Ted have been fascinated by time travel-some say drawn to it like moths to a flame. But in order to travel safely and effectively, newbie travelers need to know the dos and don'ts. Think of this handy little book as the only thing standing between you and an unimaginably horrible death-or being trapped forever in another time or alternate reality. You get: Essential time travel knowledge: Choosing the right time machine, from DeLoreans to hot tubs to phone booths-and beyond What to say-and what NOT to say-to your doppelganger Understanding black holes and Stephen Hawking's term "spaghettification" (no, it's not a method of food preperation; yes, it is a horrifically painful way to meet your end) The connection between Einstein's General Theory of Relativity, traversing wormholes and the 88 mph speed requirement The possible consequences of creating a time paradox-including, but not limited to, the implosion of the universe Survival tips for nearly any sticky time travel situation: How to befriend a dinosaur and subsequently fight other dinosaurs with that dinosaur Instructions to build your very own Rube Goldberg Time Machine Crusading-for fun and profit Tips on battling cowboys, pirates, ninjas, samurai, Nazis, Vikings, robots and space marines How to operate a microwave oven Enjoying the servitude of robots and tips for living underground when they inevitably rise up against us

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.

Is it truly possible to secure passage to a time fixed in the past or future? Even before H. G. Wells ignited the world's imagination with his classic 1895 novel, "The Time Machine," time travel has long captivated humankind's curiosity, especially those seeking answers to the universe's most inscrutable laws. According to physicist Louis A. Del Monte, there is ample evidence that time travel has already occurred, as well as an arsenal of scientific data to back up this bold assertion. Now, he reveals his own theoretical research in support of this claim in a thought-provoking, mind-bending new work, "How to Time Travel." "How to Time Travel" provides insight into this perennially popular topic, covering the science of time travel, proposed time machines, time travel paradoxes, and time travel evidence. Organized into three major sections, the book demystifies the main tenets of this complex subject, including: Time Travel Evidence, The Science of Time Traveling, and Building a Time Machine. From explaining how Einstein's theories of relativity underpin time travel to detailing proposed methods of time travel, this comprehensive book will ensure that you never look at time in quite the same way again. The book also includes several new contributions to the field, including the Existence Equation Conjecture, the Grandchild Paradox, the Preserve the World Line Rule, and the Time Uncertainty Interval. A fascinating and radical foray into popular science, "How to Time Travel" will enthrall anyone who has a consuming interest in the subject or is newly compelled to mine the universe's most confounding mysteries.

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.

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.
