Time Travel
People often wish that they could go back to the past and correct their wrong behaviors or go to the future and see what it turns out to be like. The idea of time travel has been the topic of science fiction movies and …show more content…
There are two ways presented by them in which a person can time travel forwards: time dilation and time perception. Hawking (2010) states “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 traveling into the future. This idea was first proposed by Albert Einstein over 100 years ago". The first course is to use the idea of time dilation. It has recently been claimed ( Cutnell and Johnson, 2006, p.610) that “An observer who is in motion with respect to the events and who views them as occurring at different places measures a dilated time interval. The dilated time interval is greater than the proper time interval, according to the time dilation equation”. For example, an observer might take a trip away from the Earth and back at relativistic velocities, with the trip only lasting a few years according to the observer's own clocks, and return to find that thousands of years had passed on Earth”. Indeed, “ once spaceships are built that could fly faster than the speed of light a day on board would be equivalent to a year on Earth. That's because -according to Einstein- as objects accelerate through space, time slows down around them” (Hawking,2010). Cutnell and Johnson (2006, p.60) noted, “A striking confirmation was achieved
