Imagine body that has mass and volume such that it is just a bit short of turning into the black hole. Now let's say that the body has been around for some time and has reached present state in some smooth process so that it can be in equilibrium state if such an equilibrium exists. I assume that this equilibrium state is such that density of mass increases proportionally with the radius so that event horizon does not form anywhere inside the body. Now as the pressure increases so does temperature. Now if the heat will escape from inside of the body toward outside then inside will collapse. But can it really escape? Photons going in outward direction are redshifted but photons going inward are blueshifted. So it seems that inside of the body can not really cool down. Of course photons will escape from surface of the body but then there are photons coming from the rest of the universe that would be highly blushifted. So does this reasoning seems valid? Can a static body exist without undergoing gravitational collapse even without considering degeneracy pressure?
