Hello everyone. As far as I know, even lights can not escape from black hole once the light reaches to even horizon as lights carry momentum hence energy. Now, what I wonder is, how fast do black holes swallow light or, if you will, other objects? I guess it cannot be faster than the speed of light, which is [itex]c\ =\ 2.99792458\ \times\ 10^{8}\ m\ s^{-1}[/itex], because when an object, albeit impossible, exceeds the speed of light it can thus escape from a black hole.
Imagine a pencil being swallowed by a black hole, how fast would that be? Would the object reach the speed of light(which is I guess impossible according to the general relativity but then again accepted laws of physics break down in such circumtances)?
I hope I'm not asking stupid questions. Also I did a search before submitting this, but couldn't find anything.
