  In this paper we consider a classical treatment of a very dense collection of
photons forming a self-sustained globe under its own gravitational influence.
We call this a "photonic globe" We show that such a dense photonic globe will
have a radius closely corresponding to the Schwarzschild radius. Thus lending
substance to the conjuncture that the region within the Schwarzschild radius of
a black hole contains only pure radiation. As an application example, we
consider the case of a very large photonic globe whose radius corresponds to
the radius of the universe and containing radiation of the frequency of the
microwave background (160.2 GHZ). It so turns out that such a photonic globe
has an average density which closely corresponds to the observed average
density of our universe.
