What is gravitational singularity?
A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is so intense that spacetime itself breaks down catastrophically . Gravitational singularities exist at a junction between general relativity and quantum mechanics; therefore, the properties of the singularity cannot be described without an established theory of quantum gravity . Singularities in general relativity can be defined by the scalar invariant curvature becoming infinite or, better, by a geodesic being incomplete . A gravitational singularity is a point in space where gravity is thought to approach infinity .. At a singularity, space and time cease to exist as we know them and current laws of physics cannot be applied to this region . Scientists have long been curious about what exists beyond the black hole that is at the center of our universe, as well as what could have existed before the birth of the universe . A gravitational singularity is a point in space-time where the laws of physics break down, and at the Singularity, the Universe began . There are two main types of singularities – Curvature and Conical. Scientists are still trying to understand the nature of the singularity itself and the mysteries that lie beyond it .
