I just realized something about how bizarre physical reality is.
At one end of the mass density spectrum, "perfect vacuum," physicists note that matter and energy can just "pop" into existence. One moment, nothing there, the next moment, something.
At the other end of the mass density spectrum, what we refer to as a black hole (not at the event horizon, where quantum effects assert some evaporation of energy/mass), the notions of "space" and "time" don't even exist.
The realization became that there is less to a black hole, than there is to empty space.
That part is known as "God".
