Oh god and now I just thought of how light (photons) bends with gravity but has no mass but then that's easy because it's the space time field that is warped and that's what gravity is.

But at what kind of scale does all this break down?

There are no locations, only relations. So at planck length, Euclidean space turns in to gobbledygook
