Question

As per laws of physics, there is zero gravity at centre of object then why there is infinite gravity at centre of black hole?​

Answer 1

Explanation:

there is infinite gravity at center of black hole becuase it creates more deepness in the space.

assume as if the space is a thin rubber sheet

and some balls (planets) are placed on it.

all of them will create some deepness as they will push the sheet downwards creating gravity ans anything comes near the curve slope created all around will cause the object to attract it towards the planet or object. so is black hole as it creates too much push or deepness into the space it has almost infinite gravity. and about the law of physics says that zero gravity at centre of object that is because more greater forces than gravity are acting on it such strong nuclear force which keeps the smallest units of matter (atom, proton,nuetron ) together. and gravity isn't strong enough to bind those particles. so there is no gravity at the center and if there is it has 0 effect on the particles so the law is true but black hole is a different case.
