In my opinion, time does not exist, it is simply the way to perceive movement and entropy. The time is calculated with respect to something that moves, the earth with the sun, the sun with the center of the galaxy: If everything were stopped we could not describe what happens before and what after. This is what would happen near a black hole where gravity is so strong that nothings move compared to an external observer. All this is wonderful
