How Does Quantum Gravity Affect Quantum Particles?

From afar a black hole will seem like it has zero temperature. But from the outside, it's going to look totally different. We can't really tell a story about what happens right at the edge of the event horizon for quantum objects but we can tell a story in this indirect way. People are trying to build up a theory of quantum gravity that would describe the kind of radiation we see from afar. And so people are working on that.
