Let's say that we have two planets -- planet A and planet B, 100 Lightyears apart in space. Centered directly between them is a black hole with a 25 lightyear Schwartzchild radius. (The idea is that it's 25 lightyears fromt the Schwartzschild surface to each planet.) If someone on planet A shots a stream of electrons with velocity .99c into the black hole, then awouldn't someone on planet B be able to observe the change in the black hole in approximately 50 years by observing the charge of the black hole? The electrons would take about 25 years to reach the black hole. Then the black hole would have observable charge. Since the internal structure of the black hole is unobservable, the charge should affect all of the black hole instananeously, so the other side would also be changed. Then the observation of the charge chage would take another 25 years to reach the other planet. I see two potential answers: One is that the black hole has an effective diameter of zero -- thus the distnace between the planets is actually 50 lightyears. The other is that the charge propogates along the schwartzchild surface of the black hole at c, so that it takes less time for light to get from one planet to the other by barely missing the Schwartzschild horizon.
