In classical general relativity it is known that angle of deflection is proportional to radius-1 from the center of the sun. If radius is large, this angle is very small, what happens already at the radius of the sun.
But what happens to this photon, when we include quantum gravity (QG)? I know that quantum gravity is unfinished theory. But what are the main the most simple QG approaches to the above example and where the problems arise?
