What is the singularity in a black hole?

The singularity in a black hole is a point of infinite density and zero volume.

When a massive star runs out of fuel, it collapses under its own gravity, creating a black hole. The gravitational pull of a black hole is so strong that nothing, not even light, can escape it. At the center of a black hole lies the singularity, a point where the laws of physics as we know them break down. The singularity is a point of infinite density and zero volume, where the laws of physics as we know them no longer apply.

The singularity is surrounded by the event horizon, the point of no return for anything that enters the black hole. Beyond the event horizon, the gravitational pull is so strong that not even light can escape. The event horizon is the boundary that separates the inside of the black hole from the outside.

The singularity is a point of infinite density and zero volume, where the laws of physics as we know them no longer apply. It is a point where the curvature of spacetime becomes infinite, and the laws of general relativity break down. The singularity is the ultimate endpoint of the collapse of a massive star, and it is a place where the laws of physics as we know them no longer apply.
