Query: Black Hole Radiation and Volume Statistical Entropy   The simplest possible equation for Hawking radiation, and other black hole
radiated power is derived in terms of black hole density. Black hole density
also leads to the simplest possible model of a gas of elementary constituents
confined inside a gravitational bottle of Schwarzchild radius at tremendous
pressure, which yields identically the same functional dependence as the
traditional black hole entropy. Variations of Sbh can be obtained which depend
on the occupancy of phase space cells. A relation is derived between the
constituent momenta and the black hole radius which is similar to the Compton
wavelength relation.
