Time Travel and How Black Holes make it Possible
“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 his drift along the Time-Dimension or even turn about and travel the other way” (Wells). In this quote, H.G. Wells asked one of the most commonly asked questions in time travel, why can people not move about in time as they wish? Black Holes present the opportunity to move forward in time although not in the same way as the “time machine” of popular science fiction. Time travel via black hole is completely uncontrollable, extremely dangerous, and won’t even be able to take you very far into the future. Another way of traveling through time is through wormholes, which are tiny crevices, wrinkles, or voids in the fourth dimension, time. The final form of time travel that has some scientific credibility, is to travel at an accelerated pace through time, by traveling close to the speed of light. Therefore, black holes, wormholes, and traveling near the speed of light are all theoretically viable ways of traveling through time.
According to Albert Einstein time is like a river speeding up and slowing down. Einstein realized that gravity drags on time, slowing it down; and the greater the gravitational pull of the object, the greater the effect upon time. Because of their gigantic mass, black holes slow down time more than anything else in the universe, making them natural time machines. However, going into orbit around a black hole would be incredibly dangerous, and in order to avoid the gravitational pull of the black hole, the spaceship would have to have the exactly right trajectory and speed. Even if you had a spaceship and calculations capable of entering into orbit around the Sun, you would first have to get there, and the nearest black hole, V4641 Sagittarii, is 1600 light years away. After you passed a...
