Dark quark body

  1. Jul 4, 2005 #1
    The fate of all stars seems to be they either exploded or collapse because they run out of energy. Could it be that black holes are black because the do not produce any photons. They would be dark quark bodies because they are just burned out stars. I was wondering if this makes any sense to anyone else.

    If a star that is larger than 3 solar masses dies, surpassing electron and neutron degeneracy pressures, the star implodes upon itself, creating enormous impressions of gravity. The gravity eventually becomes so intense and so concentrated that the escape velocity of the surface of the star becomes greater than that of the speed of light. The region in spacetime in which the escape velocity is the speed of light is called the event horizon. Since the escape velocity of the star is even greater than the speed of light, it means any light it might give off cannot escape from the star's vicinity. And, any light that goes into it cannot escape either. This is why black holes are black: light cannot escape to enter the eyes of any external observer. (Although hawking radiation speculates that black holes are not actually black but subtly glowing.)

    You're right in saying they're black because they don't produce any photons. Photons cant escape from their vicinity. I'm not sure what you mean by "quark bodies" though, since quarks are the constituents of subatomic particles.
