Light never slows down like matter does in gravity and can't be dragged backward. Black holes violate laws. We are not seeing black holes. What we are seeing is short of a black hole. Mitch Raemsch

In GR terms the Schwarzchild radius of any mass is like the speed of light is to mass in SR terms. The closer a mass gets to being inside it's Schwatzchild radius the slower time operates relative to when the mass was smaller/or less dense. Around this mass approaching it's Schwatzschild radius time operates slower too, just not as slow. Yes, of course, the perception in the frame is that everything is chugging along at the 'usual' pace, but it isn't from any perspective far from the object . From outside the event, the event hasn't occured yet, because it hasn't. If you understood relativity you would understand that. Mathal |
