Even Hawking has backed off the idea that nothing escapes a black hole. I see them more of just a really condensed massive mass. In effect space time has enveloped them to such a point that not even light reflects from them. I am not sold on the tear idea. They are to me just huge galactic trash compactors that regurgitate the essence of the mass they devour back into the universe to be used for future star development. Time and Spave is folded around the mass with an opening at polar ends.
