Web3 Answers Sorted by: 5 The Schwarzschild coordinates (which seem to suggest that no object ever crosses the event horizon when viewed from far outside) were derived for stationary case: no matter flows onto the black hole, the black hole has constant mass. In fact, Schwarzschild was assuming zero stress-energy tensor (vacuum solution).

WebThat means that the gravity well of the black hole must be able to accelerate from -C* to 0 instantly . Are you quoting somebody here? Anyway, this isn't quite true. Black holes don't accelerate things from -c (which I'm guessing would be a light beam trying to fly away from the singularity but inside the event horizon), to 0 "instantaneously". Web19 feb. 2024 · You can see that as mass of the black hole increases so does the radius. As such the area of the event horizon, A = 4 π R (where R=2M is the radius of our BH) increases also.
