WebAbstract. A critique of the singularity theorems of Penrose, Hawking, and Geroch is given. It is pointed out that a gravitationally collapsing black hole acts as an ultrahigh energy … On the other hand, in the center of the black hole, where the metric becomes infinite as well, the solutions suggest a singularity exists. The existence of the singularity can be verified by noting that the Kretschmann scalar , being the square of the Riemann tensor i.e. R μ ν ρ σ R μ ν ρ σ {\displaystyle R_{\mu \nu \rho \sigma … Ver mais 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 … Ver mais Many theories in physics have mathematical singularities of one kind or another.
