<br />Hi Thomas, I#'d be very interested in hearing your ideas on the temperature at the Schwarchild radius. Is it gravitationally "hot" but e.m. cold for instance? What do you make of it when it's slung into the lorentzian, as t_r/t = sqrt(1 - r_s/r)

Stoat,

I have not been implying that the central object is a black hole (which in my opinion don't exist anyway, considering the theoretical flaws in GR). As I said in my previous post, the reason the object is apparently not emitting any visible light is simply due to its high temperature (which in turn is related to the high gravitational potential energy of the object (assuming it has a mass of several million solar masses)). The radiation is only emitted in the x-ray and gamma ray region (because this is the typical radiation that plasma particles of such high energy would be emitting if they recombine).
