Of course, this stuff [coming to be a black hole through accumulation of mass] only occurs at the edges. In the center, (where we presumably are) things carry on as normal. NOOOO!!! Wrong! This person should be castigated! There is no physical singularity anywhere in your standard large enough gravitating mass, at the initial time. In a uniform mass, things will collapse to a singularity first at the center; the conditions defining the event horizon (the "edges") might be observed by a synoptic observer in that light travelling outward (the best possible escaping signal) here finally collapses into the singularity and here finally recedes in a "hyperbolic" orbit, most of its energy sapped and red-shifted as a distant observer might see it. Consider that in a 3-spherical universe, everywhere is equally "central"; and with any positive density (I believe) everything becomes singular after the same lapse of time.
