>>23170382Going back in time is impossible due to how physics work, but time travel to the future is actually possible, but you will need a good enough spaceshipthat can somehow withstand being near a black hole. By flying around the black hole very fast in your spaceship, time begins to slow down inside the spaceship. The problem is that you can’t go back again, so if you return to earth and it’s ruled by apes all of a sudden, you know you made the wrong decision.
