Hi Armin,
ad microscopic states:
In fact I describe completely the microscopic states of the black holes (actually only for ideal gas particles), and can from these derive all macroscopic variables. I cannot give explicit formulas - I can only calculate the data numerically. In my opinion the model is not applicable to standard vacuum solutions. I consider it as an alternative concept (or even a counter - concept) to standard vacuum solutions. In the chapter titled "intuitive example" I argue, that a gravitational collapse through the Schwarzschild radius is unphysical and impossible and therefore the same is the case for vacuum solutions.
Ad condensed matter analogues:
Up to now I read about these experiments only in some popular physics websites. I did not have these in mind in connection with my model. I think, this is an interesting idea, which may bear some fruits in the future. It might be that not only vacuum solutions can be modeled, but also my non-vacuum solutions. I would like to read a bit more about these experiments. Do you have some list of names (with which I can search in arxiv.org) or a list of websites, regarding this topic?
Ad predictions in general:
I was a bit cautious in my document regarding predictions, however there are a few basic predictions of the model. They concern the black holes directly (and not models), so here I give them to some extent: There is a smooth transition from neutron stars to black holes, black holes are in fact neutron stars with a "hole" (a rather empty space) in the middle and with a heavily changed metric. Black holes have a temperature (e.g. 1 billion Kelvin) and they therefore emit light corresponding to a black body radiator having that temperature. They get their energy for radiation from their thermal energy and also as gravitational binding energy via a slow contraction. The black body radiation follows quite naturally from the model - standard vacuum solutions have some problems with a plausible explanation.
Many thanks for your interesting comments, and please, if easily available, provide some info about condensed matter analogues.
Johann
