![]() If a person were to hang out near the edge of a black hole, where gravity is prodigious, Goldberg says, only a few hours might pass for them while 1,000 years went by for someone on Earth. “Near massive bodies-near the surface of neutron stars or even at the surface of the Earth, although it’s a tiny effect-time runs slower than it does far away,” says Dave Goldberg, a cosmologist at Drexel University. And according to Einstein’s general theory of relativity, gravity also affects clocks: the more forceful the gravity nearby, the slower time goes. The quicker you travel, the slower seconds pass. According to Einstein’s special theory of relativity, time’s flow depends on how fast you’re moving. Time traveling to the near future is easy: you’re doing it right now at a rate of one second per second, and physicists say that rate can change. In fact, the laws of physics might allow chronological hopping, but the devil is in the details. Scientists don’t think this conception is likely in the real world, but they also don’t relegate time travel to the crackpot realm. What these films show is basically time teleportation. ![]() They then reappear instantaneously among cowboys, knights or dinosaurs. ![]() In the movies, time travelers typically step inside a machine and-poof-disappear. ![]()
