WebThis was the singularity the theory predicted. The results were proved rigorously mathematically, using certain properties of differential equations and topology. Now in this framework, spacetime is assumed to be smooth - it's a manifold - it doesn't have any granularity or minimum length. 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".

WebString theory is used in the context of quantum physics that is used to understand quantum phenomena. The basic structure of a black hole consists of a singularity hidden by … WebOnce an event horizon forms, all of the matter inside must collapse to a black hole. This is the key difference between a neutron star and a black hole--a neutron star is made up of (very dense) ordinary matter in a stable configuration. A black hole is essentially a pointlike or ringlike concentration of mass with infinite density.
