I read that if an observer were to watch as another observer fell into the black hole, eventually observer A would see B stop before reaching the event horizon. I'm having a little trouble with this and have to questions about it. 1)If we turned an extremely powerful telescope at a black hole, would we see all the matter that the black hole has pulled in frozen at the event horizon? 2)When a star is collapsing to form a black hole, after enough mass has been compacted and a black hole has formed, then shouldn't whats left of the collapsing mass be frozen outside of the event horizon again? Making it seem as though it never colllapsed completely into a black hole, to an observer outside the event horizon?
