Question

Quizplus · Accepted Answer

A singularity is a point within a black hole where the gravitational pull becomes infinite, and the laws of physics as we know them break down. It is also where the mass is compressed to a point of zero volume, making it a point of infinite density. This is known as a "gravitational singularity."
