If you could go back in time, what would you do differently? Or do you prefer to fast forward and see how the world is like in the future?
While the journey does not exist at the moment, it may be possible according to the theory.
Physics Albert Einstein theorizes that time is relative depending on how fast you travel.
For example, the faster you move in the room, the slower you move on time.
Astronauts in the international space station are, to a certain extent, already travelers in the sense that they do things for a fraction of a second in the future.
