String theory specifically fails to predict/explain gravity. Most versions aren't even background-independent, so they just assume spacetime is a thing. So no.

String theory specifically fails to predict/explain gravity. Most versions aren't even background-independent, so they just assume spacetime is a thing. So no. This seems weird because LQG is at least trying to be background independent. And spacetime isn't just a thing, it's the thing that needs to be explained in quantum terms. Concentrating on particle-ising (or operator-ising) gravity seems like missing the point to me. But I'm not remotely a pro, so I could easily be missing something important.
