Time Travel And It´S Theories Essay

1008 words - 4 pages

Time travel has always been an ambitious dream in science fiction. Writers such as H.G Wells not only kept their readers mesmerized by great novels such as “The time machine” but also introduced the idea of time travel in the imagination of their readers. Today time travel is not regarded as strictly science fiction. Einstein’s Special Theory of Relativity permits a unique kind of time dilation that would ordinarily be called time travel. The theory states that, relative to a stationary observer, time appears to pass more slowly for fast-moving bodies. For example, a moving clock will appear to run slow; as a clock approaches the speed of light its hands will appear to nearly stop moving. So if one can move information from one point to another faster than light then according to special relativity, there will be an observer who sees this information transfer as allowing information to travel into the past.
One of the greatest scientists of our time Stephen Hawking was once quoted to have said “I do believe in time travel, Time travel to the future. Time flows like a river, and it seems as if each of us is carried relentlessly along by time's current. But time is like a river in another way. It flows at different speeds in different places and that is the key to travelling into the future. This idea was first proposed by Albert Einstein over 100 years ago."
A number of people have claimed to be time travelers, for example, Darren Arthur Daulton, who is a former catcher in Major League Baseball, had claimed in a televised interview with ESPN that he has "skipped through time" and has undergone “astral travel”. However, none of these claims have ever been proven true.
The concept of time travel is laden with a number of paradoxes one of the most famous being the grandfather paradox, which was first described by the science fiction writer René Barjavel in his 1943 book Le Voyageur Imprudent (The Imprudent Traveler). The paradox is this: suppose a man traveled back in time and killed his biological grandfather before the latter met the traveler's grandmother. As a result, one of the traveler's parents (and by extension the traveler himself) would never have been conceived. This would imply that he could not have traveled back in time after all, which means the grandfather would still be alive, and the traveler would have been conceived allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation.
A number of ways to time travel have been proposed such as by using wormholes, Massive Spinning Cylinders and Quantum Entanglement. However, time travel by any method has still not been possible.
The possibility of time travel has been given a new hope by the recent theory of Vanderbilt’s Thomas J. Weiler and Chiu Man Ho. They have proposed that the Large Hadron Collider (the world's largest and highest-energy particle accelerator built by the European...
