Gravitational singularity - Wikipedia
WEBA gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when".

WEBJul 11, 2018 · In mathematics, a singularity is a point for which a mathematical expression is not defined. For example, consider the mathematical expression 1/x. If x=0, the expression yields infinity. In other words, if you divide 1 by 0, it can be divided an infinite number of times.
Gravitational Singularities - an overview | ScienceDirect Topics
WEBGravitational singularities refer to remarkable indicators in physics that suggest a change in the description of physical reality or the need for a quantum version of gravity. In General Relativity, there are three fundamental types of singularities: black hole spacelike crushing singularities, Big Bang singularity, and Big Rip singularity.
A critical appraisal of the singularity theorems
WEBMar 14, 2022 · The 2020 Nobel prize in Physics has revived the interest in the singularity theorems and, in particular, in the Penrose theorem published in 1965. In this short paper, I briefly review the main ideas behind the theorems and then proceed to an evaluation of their hypotheses and implications.
