This is a thread attempting to comprehend the physics behind the theory in the description of Black holes in LQG. There has been very much debate about the minimum value that a puncture can have in the horizon of a BH. The fact is, if a puncture disappears from the horizon, then the horizon reduces its area. It suggests that in LQG the horizon is something real, has physical existence. Do you get the point? In GR, the horizon is something theoretical, there's not a real spherical sheet surrounding the BH. But here the things seem different. Then my question is : what's this material that composes the horizon in LQG? What's the horizon made of? another question is: Is in LQG a black hole still a singularity? If not, there's some formula that relates its mass with its volume?
