I wanna know if there's zero gravity in the center of a blackhole. Think about it shouldn't the gravity cancel itself out in the middle?

Big brain answer but I think since there's gravity coming from every direction you'd be stuck in the middle couldn't move or anything. So there would still be gravity and it wouldn't cancel itself out because if there was no gravity you could move freely

Since there's no field due to an r-squared force law inside a spherical shell, I'd think you shouldn't feel any gravity in the centre. Moreover, there should be some region around the centre where the portion of the black hole's mass "more inside" isn't much of a black hole. On the other hand, the density would still be black hole-like, so I'm probably wrong.
I don't know GR, so I could very well be missing something there as well.
