Kevin Vandersloot is an Ashtekar PhD now at Portsmouth UK with a EU Curie fellowship. He and another EU postdoc, C. Boehmer, have been studying the interior of the LQG black hole. As we know, the big bang can be modeled using LQG and it gives no singularity (no place where the model blows up and fails to compute). Well, also the black hole interior (inside the event horizon) can be modeled with LQG, and it gives no singularity. But it gives different results from the big bang model.! Vandersloot gets that an idealized test particle falling into the center of a LQG black hole undergoes damped oscillation and stabilizes at a distance of 0.4 - 0.5 plancklength from the origin. In other words, if we use this idealization of how matter would behave, what we see is something at the center which is about 0.8 - 1.0 plancklength in diameter. And this is INDEPENDENT OF THE MASS OF THE BLACK HOLE. Sounds crazy right? Well Kevin gave an ILQGS seminar talk last Tuesday with Ashtekar and Rovelli and others asking questions. The audio, and his slides are online. It sounded pretty clear and cogent to me. There are various ways to model BH interior using LQG and you have to remember we are just talking models so far---no help from experiment as yet. But like the case with the big bang one can at least CALCULATE stuff, and the model Kevin and C. Boehmer were using is well motivated compared to several earlier studies i've seen of quantum BH interior. Vandersloot and Boehmer have a recent paper about this posted on arxiv. But I would recommend the audio and PDF you find at the ILQGS website. It is the seminar talk dated 27 November. I experienced the seminar talk, with the questions and answers, as extra informative compared with the paper.
