Irrefutable Proof of The Non-Existence of a Gravitational Singularity at The Centre of a Black Hole

Astronomical observations confirm that gravitational force decreases with the square of the distance. If the gravitational force in the centre of Sagittarius A* were close to infinity and would decrease with the square of the distance, our Milky Way could not exist as we observe it. This fact is irrefutable proof that there is no gravitational singularity in the centre of Sagittarius A* and in general, there is no gravitational singularity in the centre of a black hole.
