Time travel is feat thought by most to be impossible. After all time travel is what many science fiction movies are made of. Let us not forget such movies as “Back to the Future” or “The Time Machine.” Yet unlike those movies time travel is not necessarily fiction. “We are in our own time machines, our hearts are pumping blood, we're breathing, we are existing through time (at least until our own personal time machines seriously malfunction).” (Need help citing this!) Still surrounding this topic is a series of theories, and surrounding these series is a number of flaws. Theories and flaws that need to be explained to fully understand the idea of time travel. First things first we must state the basics.
To begin with throw away whatever you thought you ever knew about time travel. There is no such thing as working time machines, you can’t go back in time by falling into a black hole, and sitting in a tub of water is not going to change you molecular structure and send it back in time by having you float through a wormhole. Time travel is achieved through speed; theoretically you must reach close to light speeds to go forward in time and faster than light speed to go back in time, according to Einstein’s theory of relativity mind you. Einstein’s theory of relativity is the basis of all time travel theories (Davies 1), “The essence of his prediction is that time is not absolute and universal but depends on the observer’s state of motion.” (Davies 1) States Paul Davies of the University of Adelaide in Australia, and writer for Sky & Telescope Magazine. “This implies that two observers moving at different speeds, say, will measure different time intervals between the same two events.”(Davies 1) For example say there are two people, Bob and Bobette, if Bob is traveling at x speed and Bobette is traveling at a speed of 2x, the amount of time passing would differ between Bob and Bobette. So what does this have to do with anything? Well I’ll tell you. Now this is pure fiction it is being used to show a point. Say we are traveling to Andromeda, which is 2.2 million light years away (help). We first set the acceleration to 1g (the gravitational field of the earth) because if we could accelerate to infinity we would be smashed to the size of an atom (help). So at 1g we should reach our maximum speed (the speed of light) in 354 days (help). After that it would take no time to get there at all since the time to get there would have shrunk to zero (help). So assuming we go there just to come back, it should take us a little under two years to get there and back. So we would have only aged two years, while the earth would have aged 2.2 million years. Thus us theoretically we would have travelled to the future. ...
