String Theory & LQG: Explaining Particles & Forces

[Eh]

In string theory, all particles and forces of nature of mere results of vibrating strings. Can LQG offer an alternative explanation for the zoo of particles we find? I seem to recall reading that the theory proposes that quarks are where edges of the lattice intersect, but I can't recall where. Is this correct, and has any progress been made in explaining the source of the forces?

Ideas about how to move beyond pure gravity LQG are vague. The most natural (vague) idea is problematic: LQG black hole entropy calculations appear to indicate insufficient room in LQG for any other particles.
