Well. Obviously when stars collapse into a black hole, they emit light, or ultraviolet. So not everything collapses into a black hole, particularly when its energy is no longer gravity bound.
You could say there is an overspill in comparison to what its gravity wants. In some cases however the whole star disappears, so its gravity was unsaturable in that one.
Your best chances are at the outer edge. As travelers on the Titanic instinctively understood as well.
You could singlemindetly regard it as water always flowing to the lowest point/ but when you understand it creates wels just as well, you get a different vision of it.
