Homonym: Singularities (Events)
A singularity refers to a point in space or time where certain properties become infinite or undefined. In the context of black holes, a singularity is the core where gravitational forces compress matter to an infinitely small point, leading to extreme density and curvature of spacetime.
In mathematics, a singularity can occur in functions where they become undefined, such as division by zero. These points can lead to interesting behaviors in equations and are often studied to understand the limits and continuity of functions.
