"(PhysOrg.com) -- As a quantum theory of gravity, loop quantum gravity
could potentially solve one of the biggest problems in physics:
reconciling general relativity and quantum mechanics. But like all
tentative theories of quantum gravity, loop quantum gravity has never
been experimentally tested. Now in a new study, scientists have found
that, when black holes evaporate, the radiation they emit could
potentially reveal “footprints” of loop quantum gravity, distinct from
the usual Hawking radiation that black holes are expected to emit. "

"When black holes evaporate..."= never.
