"If I travel to the Future, I am part of the Future. Importantly, I was Always Part of the Future." The classic approach to time suggests that we move through it like a ship sailing on water. There is an opinion that it is possible that time does not move forward, but rather, everything in time is ever-present. According to the block universe theory, if we were to ‘look down’ upon the universe, we would see time spread out in all directions, just as we see space at the moment.
