Chronometric singularity

Chronometric singularity is a theoretical concept in physics and cosmology that arises in the context of general relativity and the study of black holes. It refers to a point in spacetime where the laws of physics, as we currently understand them, break down, primarily in relation to time and causality. In mathematical terms, a singularity is a point at which some quantity (like density, temperature, or curvature of spacetime) becomes infinite or undefined.
