The surface of the object crossing the event horizon. Surely if no more light can escape due to the gravitational field being too strong it must head back towards the surface of the body.
Just a quick question, possibly a silly one.
If a black hole gains enough matter and energy, could it eventually explode in the same manner the Universe did when the Big Bang happened?
So then what about black-holes?
They appear black because the gravitational field is too strong for light to escape (correct me at any point, as I said, not too clued up!). Does this mean that any light which reflects reflect off the surface of the body is slowed to a stop and then pulled back...
The reason I ask is that if gravity can have an effect of the physical elements within light regarding its direction, then might it be possible for it to affect its speed in a straight line?
I understand the idea of the speed of light being constant, though I can't help but wonder.
Thanks for...

I'm not too clued up on things of this nature and so thought I'd ask a question.
If extreme gravity can bend light then can it speed it up or slow it down?
