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.

An exciting and informative guide to the history of time travel cinema, drawing from the earliest days of the genre right through to the latest releases. "Travels in Time" considers all of the various elements which have helped to make time travel movies among the most memorable features in all of science fiction.

From the bestselling author of Jurassic Park, Timeline, and Sphere comes a deeply personal memoir full of fascinating adventures as he travels everywhere from the Mayan pyramids to Kilimanjaro. Fueled by a powerful curiosity—and by a need to see, feel, and hear, firsthand and close-up—Michael Crichton's journeys have carried him into worlds diverse and compelling—swimming with mud sharks in Tahiti, tracking wild animals through the jungle of Rwanda. This is a record of those travels—an exhilarating quest across the familiar and exotic frontiers of the outer world, a determined odyssey into the unfathomable, spiritual depths of the inner world. It is an adventure of risk and rejuvenation, terror and wonder, as exciting as Michael Crichton's many masterful and widely heralded works of fiction.

A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson). It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur. Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American, Time, and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” (Booklist). “Impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read.” —Publishers Weekly

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.

World-renowned zoologist and photographer Naskrecki leads readers on a time-lapse tour that renders Earth's colossal age comprehensible, visible in creatures and habitats that have persisted, nearly untouched, for hundreds of millions of years.

Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Do space and time really exist, or are they simply the constructions of our minds? Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions, and many other mind-boggling puzzles and paradoxes. No prior knowledge of philosophy is required to enjoy this book. The universe might seem very different after reading it.
