Like if you're traveling at the speed of light or near incredible gravity like a black hole you age slower????? I get the clock argument like if youre traveling away from the clock at the speed of light you perceive it differently and dont see the clock tick but you still fucking age at a second per second and so does everyone on earth right!??!?!!? So what's the fucking point???? I watched interstellar and they were on waterworld for like an hour and black dude ages like a billion years how the fuck does that work?????? I don't fucking get it, is this shit a scam????
