I don't like the idea of anything crossing the event horizon of a black hole from any observer's view point. The closer something gets to the event horizon, it either appears to slow down, or the event horizon appears to stretch and move further away. How can anything cross it? For this reason, i like the idea that all the energy in a black hole is concentrated in a shell on the surface. This, in turn, leads me to believe that all matter is energy condensed around localized coordinates. Unfortunately, I don't have any citations or math to back me up. I'm curious how much legitimacy there is to these thoughts.
