Does quantum gravity challenge spacetime's rectilinear motion?

Does quantum gravity argue that space is not singularly occupied by rectilinear motion?I am reading a general relativity intro sort of thing and this inquiry popped up in my mind. The text was explicating space being occupied by only rectilinear motion and I wondered if quantum gravity could be the antithesis.

This was completely unclear. Are you using an auto-translator? Maybe another one would work better.

Excuse me if I'm unclear, I've only recently begun with grasping gravitational study. My understanding of relativity is one of singular, rectilinear motion. Since it was established by classical methods, I wondered what that entailed by quantum means.

I'm sorry, but I have no idea what you mean by "singular, rectilinear motion".

I mean parallel motion between two particles. Does gravity not consist of its own?
