A singularity is a location in space where density is infinite and volume is zero. It is the “point of no return” taken to its absolute extreme—everything that enters a black hole eventually ends up here. It is a strange location because of the “Divide by Zero” Problem. For E.g In mathematics, if you divide something by zero, the answer is undefined. But in physics, the singularity is where the universe “divides by zero.
