How can you time travel?

Answer 1

it isn't possible at the present. I'm only 16, but theoretically, astronauts who come back to earth are a couple of seconds or minutes younger than they should be. for them, the faster they go, the more time seems to "slow" until when you reach the speed of light, time would seem to "halt" for the person (s) or object (s) in motion. but, if they went the speed of light, and had a beam of light next to them, the light beam would still be moving at the speed of light, RELATIVE TO THEIR PERSPECTIVE. if you went faster than the speed of light, then time would seem to reverse itself. according to Einstein's Special Theory of Relativity, Energy(E) equals Mass(M) times a constant(c) squared(^2). aka: E=Mc^2. your constant can be anything. Einstein merely used the speed of light and calculations could not reach that far as to see what the mass would equal. you would not have an infinite mass. that is IMPOSSIBLE. no matter what, you would always have a finite mass. therefore, it can be calculated, just after a LONG time. mass effects gravity. therefore, as your mass increased, your initial gravity would increase, which (as studies show) affects RELATIVE time. theories show that some black holes could be traverable wormholes. having a black hole with a rotation, the singularity could be skipped, and you could come out in another universe. BUT the Einstein-Rosen Bridge would not be crossed, because it always closes right before you reach the point of crossing. so you could see into another universe, but be crushed to the size smaller than a carbon atom moments later.

think of space being a flat surface, a grid if you will. and the z axis being up and down. time is interwoven into all 3 axis. and you have a body with large mass, therefore large gravity, in the center of the grid, the grid would warp around the object, thus changing the time dialation. the larger the gravity, the more it warps.

to the object or person in motion of going through time, they would seem to us as going into the future, but to them, they would be going into the past. this makes it all the more dangerous. for religious peoples and such, if we didnt have proper instructions on when this person would show up again and how they looked, people could think of him as the second coming of christ and cause mass hysteria.
