Sorry, I meant to say: for theories of quantum gravity, spacetime is discrete. I got ahead of myself there.
Even then it's not every theory of quantum gravity, but certainly those with any traction have tended to discretise spacetime (e.g. loop quantum gravity).
And yes I was trying to keep it simple/accessible. Given the parent question, why would I word my response inaccessibly?
