By showing us how small in space mass can be, black holes continuously generate space.
But black holes do not generate space?
@tobogganablaze True, they compress space and leave the rest.
Ah, you mean they compress matter and then free up the space that matter occupied. Now it makes sense.
It’s really confusing when you talk about a cosmological topic but then use “space” in a non-cosmological sense.
@tobogganablaze Originally I had this idea: If the universe decreases in density since big bang but its radius is still the same, then a lot of space must be sucked inside space-bending structures like black holes. Also, may be matter has big bang density inside of black holes.
So, black holes are maintainers of constant entropy in a constant radius universe. Thus they must be space generators.
