The final fact of a blackhole is that you CAN'T see it.. I have done a lot of studies/physics concerning stelar singularities etc. What makes a black-hole black is that it has so much mass that actual light waves (fast moving matter = energy = e=mc^2) can not escape its gravitational field. Now, all that allows us to see is light. without light being emitted/reflected by the blackhole, we can not see it at all. The only way we can actually even prove blackholes exist is because of stelar paralax and the fact that starlight will bend around a black hole, thus we see stars on both sides (the same star)... Sorry, just saw blackhole and thought I'd insert my two cents. For being a 'black' hole, it is rather 'white'.
