What Happens to Time Near a Black Hole?
A black hole is a volume of very high gravitational field and thus of severe warp in the spacetime continuum, so much so that light from the inside cannot shine out beyond the hole’s horizon. Time slows down for a person falling toward the surface (horizon) of a black hole. Time goes infinitely slowly at the surface-horizon of the hole, where velocities slow to zero and temperatures becomes infinite, as judged by us from far away. But from the perspective of a person falling through the horizon of the hole, time is normal, temperature is normal, velocity is normal but increasing, and there’s no noticeable surface or boundary. As in most other galaxies, there is a massive black hole at the center of our galaxy. It is in the direction of the constellation Sagittarius. Astrophysicists believe black holes are commonly formed by the inward collapse of stars that have burned out, stars that are at least two and a half times larger than our Sun. The center of a black hole (sometimes called “t
