Black holesBlack holes are interpreted to have a "break down" of general relativity at their point of singularity. The region near the singularity is expected to be described by some theory of quantum gravityquantum gravity.
Since quantum gravity is expected to describe the physics near the black hole center, black holes would make for great laboratory environments for observing the effects of quantum gravity.
The problem with using black holes to probe quantum gravity, other than them being very far away, is that black holes supposedly prevent anything from escaping beyond the event horizon.
I want to ask if there are any successful or serious theoretical attempts at overcoming the problem stated above.
