As long as we are talking esotericlly, I think of fixed points on a primordial map. Like the fabric of everything and where the aether concentrates celestial bodies emerge. Like the backside of a cross stitch where we only see the stitch work rather than the image.

edit:

I don’t know enough about black holes to speak credibly on the subject but another thought comes to mind.

Pretend there is a loading point for any fixed volume of space that when the gravity gets massive enough matter can collapse in on itself. That matter still exists but it now occupies space within matter.
