Black holes formed by stars etc gathering matter and eventually having so much mass that light cannot escape, fair enough but this does not make it a "hole".
Ok thanks GV, so its really about the distance/size of the event horizon because there is still a lump of "stuff" in the middle (squashed to the size of Paris?). Therefore its still not a "hole".
According to Hawking Radiation, a black hole will emit particles as well as draw them in. No idea how much, just something I heard someone talk about a while ago.
But how does it emit particles if nothing can escape, not even light?
