Also remember that time moves slower near higher gravitational forces than it would where there are less gravitational forces. From afar, that spot may seem empty, but in reality, it's likely just slightly less dense than elsewhere while time moves ridiculously faster there due to that slightly less dense area and subsequent less gravitational forces, therefore being unobservable to us.

the universe is a closed-system that folds into itself over and over, infinitely.

A thought,

I've read before that to find that point of where it loops into itself, to find a point where density "appears" to be starkly different from each other, so I wonder if there is an abnormally dense (from our perspective) area that would match the perceived size of this hole anywhere... hmm.. I guess we would never know because things change depending on gravity and perspective..

We as humans can only guess..
