WebSep 27, 2024 · First, General Relativity does seem to predict singularities as arising under some very general conditions of gravitational collapse, as shown by the Penrose-Hawking singularity theorems. So... A 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 … See more Many theories in physics have mathematical singularities of one kind or another.
