Time stops inside a black hole? I doubt it. But it is standard theory. If it does stop inside a black hole, then it probably doesn't exist to begin with. The photon or any other mass-less particle that [must] move at the speed of light supposedly doesn't experience time. I doubt that too:
Can something move if there is no time? Or is it like, it's in all those places, it's just our illusion of time that makes us think it's in different places?
When a black hole sucks in light, does the light slow down and cause it to transform from energy into mass?
(no fancy math needed because I won't understand it, I'm happy to hear it described in words)
