The rate at which literally our clock's tick is slower, closer to the Earth than it is further away. When you hit the horizon, technically, you've rotated all the time away. That's why the center of the black hole is in the future time direction and not in the space direction. And this is a real effect even around the Earth. We correct our phones correct for relativistic time dilation.
How do supermassive black holes form? Neil deGrasse Tyson and comedian Chuck Nice come to you live to learn about the history of black holes, what’s inside them, and new discoveries with cosmologist Janna Levin and astrophysicist Jenny Greene.
