Hi All , I have a question which is at least partly one of believe but I would be interested in your opinion. We know that there is some problem with the black hole's entropie. If some object with entropy S collapses and it evaporates completely via Hawking Radiation, then where has all the information about the initial state gone? There it is: the information loss problem. My point of view about this is that the information loss problem can only be solved if the singularity in the inside is avoided. Let us therefore assume that there is no singularity inside the black hole - it is avoided by some unknown quantum gravity effect, but the stuff is dense and stable inside the horizon. I found that my point of view about the entropy is kind of unusual. Consider, there is some matter which collapses. It has entropie S. This stuff forms a horizon by which the inside region gets completely causally disconnected and with it all information about the initial state. Then, the horizon makes Hawking radiation, which is what we see from the outside. It comes with an entropy S_H, which is what we usually call the entropy of the black hole. In contrast to this, I say, there is more entropy inside, it just can not interact. http://xxx.lanl.gov/abs/hep-th/0501103" comes with the following argument against this: If the black hole has more information inside, then there are arbitrarily many black holes which look alike from the outside. This would mean that in a pair production process of black holes, the phase space would be arbitrarily large. Which we would not really want it to be. Besides the fact that I don't really know how I should describe the pair production of black hole's :yuck: , I don't see why this should be the case. Sticking with my point of view, the produced black hole is just a gravitationally extremly strong bound system of particles. But these still have to be particles and should have been produced. Thus, the black hole's phase space would be that of whatever particles could be produced (say, some quark pairs or photons or whatever). You could say, they are still produced, they are just so clumped together that they have a horizon. Does that make sense? Or have I misunderstood the pair production argument?
