An answer may come from the attempts the people are making to try to develop a theory of quantum gravity because under one of the models for this called up loop quantum gravity spacetime itself almost consists of, like, you can think of it is like a little a atom of spacetime; and one possibility is that when you start to cram everything very close together when space itself is packed down into a small enough point that it can't keep shrinking it, it can't keep compacting it.
