So far quantum loop gravity is no better at making testable predictions than string
theory is.
Actually I think LQG predicts that there should be some dispersion for very energetic
photons. A prediction that seems to have be falsified by the simultaneous arrival of
different energy gamma rays from very distant supernova. The result indicates spacetime
is smooth down to 0.002 of the Planck length.
