Time Travel : According to Current Physics
There is nothing in science fiction that is thought about more than time travel. Instead of taking a vacation to Disney World, or a remote island, one could go on vacation to July 4th 1776. Instead of going to one's grandmother's house for Thanksgiving dinner, one could spend the day with their Great-Great-Great Grandmother and Grandfather. Rather than celebrating an anniversary with one's spouse, a couple could venture to the place and hour that they were wed. When time travel is safely achieved, the possibilities will be endless. Time Travel is equally as easy to daydream about, as it is hard to accomplish. Considered the hardest physically possible task by great physicists such as Albert Einstein and Niels Bohr, it was even thought to be physically impossible by early physicists including Sir Isaac Newton. "Man... can go up against gravitation in a balloon, and why should he not hope that ultimately he may be able to stop or accelerate is drift along the Time-Dimension, or even turn about and travel the other way" -H.G. Wells, The Time Machine, 1895 The idea of Time Travel was brought into the mainstream by H.G. Wells with his famous novel The Time Machine in 1895. Wells wrote about a man whose fiance had
For the rest of this essay, Newtonian physics will be ignored due to the loopholes and unanswered events in Newton's explanations. Much like Einstein improved Newton's laws of physics as time progressed. If a galaxy is ten light-years away, it would take ten years traveling at the speed of light to reach. Up until Albert Einstein, the Newtonian world of physics (derived from Sir Isaac Newton's Laws of Physics) was the unchallenged method of explaining how objects moved and interacted. This implies that when one sees something, they are seeing it as it was a small fraction of a second ago. Wells, The Time Machine, 1895Albert Einstein would use this concept of time being the fourth dimension only ten years later when coming up with groundbreaking revelations on the possibility of time travel. One second would be measured as one second whether one was on earth, mars, stationary, or traveling at the speed of light. 995 percent of the speed of light towards an object 500 light-years away, turns around and came back at the same speed. Through the use of wormholes, time travel to the past is possible. In Newton's world, time was a constant. This theory seems valid, but it is greatly doubted that a speed greater than the speed of light could be achieved. Einstein proved that if an astronaut got into a spaceship and traveled 99. Even if humans ever did learn how to manipulate wormholes to travel through space, it would be through preexisting black holes. In laboratories, scientists have accelerated particles close enough to the speed of light, that time travel could be achieved, and that has cost millions of dollars.
