we all know that a black hole is a body so heavy that nothing cannot escape it's boundaries, not even light, because the escape velocity from a black hole is larger than C, but we also know that stars are only able to light up and produce fusion if they are massive enough and the pressure is strong enough for atoms to fuse. as far as I know there is no rule for a maximum pressure, beyond wich the atoms would not fuse. and when a massive star colapses it either becomes a neutron star or a black hole, and in my opinion the only difference between a neutron star and a black hole is the weaker gravity from a neutron star. what are your thoughts on this, is a black hole still fusioning atoms and producing light? just because the light will never escape the event horizon doesn't mean it isn't producing light.
