Some statistical mechanical properties of photon black holes

shown that the critical temperature for Bose-Einstein condensation for relativistic particles of ‚ = fiRs is always well below the Hawking temperature of a black hole, in support of the proposed internal configuration. We then examine our results from the point of view of recent loop quantum gravity ideas and find that a natural consistency of both approaches appears. We show that the Jeans criterion for gravitational instability can be generalised to the special and general relativistic regimes and holds for any type of mass-energy distribution.
