A black hole contains a singularity where density and gravity become infinite.

According to Einstein’s General Relativity, when a massive star collapses under its own gravity, it forms a black hole with a singularity at its center. This singularity is a point where the curvature of spacetime becomes infinite, and the known laws of physics cease to provide meaningful descriptions. It represents a breakdown in our current understanding rather than a physical object we can directly observe. This concept arises mathematically from the solutions to Einstein’s field equations describing black holes.
