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.

The group uses radio pulsar timing observations acquired at NRAO's Green Bank Telescope in West Virginia and at Arecibo Radio Observatory in Puerto Rico to search for ripples in the fabric of spacetime.

Now this comes from a, this piece of it comes from a 2003 paper by a planetary scientist named Jack Wisdom at the Massachusetts Institute of Technology; and what he discovered is that you can move, as you [were describing] through curved space by moving, [let's] say, your arms and legs, or if you're an alien as it is described in the article, a tripod alien — just for the simplicity of demonstrating how the movements are with, sort of, heavy feet and a ball at the end of the tail that helped to move the [weight] around, just to make it kind of simple to look through — you can move through curved spacetime without pushing against anything, and this is the key here.

You know, for instance around Earth, you can think of gravity as forming a kind of a well around Earth, which causes the things that pass near Earth, the moon I would say, which is orbiting on its path, to stay within the vicinity because it falls into that gravity well, metaphorically speaking; and in likewise the same way this astronaut that is fictitiously described by our good mathematics professor takes a journey through curved spacetime.
