This never made any sense to me whatsoever.
I’ve see all the physicists (Michio Kaku, Stephen Hawking, Neil DeGrasse Tyson, etc.) explain this principle but it doesn’t make sense. They say that if you were to go to the moon and back at a certain speed near the speed of light, you might return to Earth a thousand years into the future like what happened in Planet of the Apes. But if you were going at the speed of light, you would arrive at the time light takes to arrive there. Why the dip? What is being missed?
Another important thing to mention is that you can’t exceed the speed of light. going to the moon and back at 99.99% the speed of light would maybe feel like a millisecond to you but like a few seconds to people on earth, but you wouldn’t go far into the future.
