Is the singularity at the centre of a black hole subject to quantum effects and would they influence the event horizon?

Is the singularity at the centre of a black hole subject to quantum effects and would they influence the event horizon?
by

1 Answer

Answer :

answer:I don’t see how we could know given current methods of measurement. We can’t see inside the event horizon because that’s the point beyond which light cannot escape. So the event horizon appears as an impenetrable globe surrounding the black hole. The laws of physics can’t be in effect inside a singularity, because the conditions there violate them. Light has no speed. Density of mass approaches infinity. Our laws explode in our paces when fed conditions like these.
