General relativity (12) Mathematical methods in general relativity (1) Physics theorems (1) Theorems … One of them says that singularity theorem says that all expanding cosmologies like our own have to begin with a singularity. Singularity; Interpretation and significance; Elements of the theorems; Nature of a singularity The Penrose–Hawking singularity theorems are a set of results in general relativity which attempt to answer the question of when gravitation produces singularities. The Penrose-Hawking singularity theorems characterize spacetimes in the theory of Einstein-gravity (general relativity) which have “singularities”, points where the Riemann curvature is undefined (or would be undefined if these points were included in the spacetime manifold) such as appears notably in black hole spacetimes.

The Penrose–Hawking singularity theorems are a set of results in general relativity that attempt to answer the question of when gravitation produces singularities.. We show that the Hawking–Penrose singularity theorem, and the generalisation of this theorem due to Galloway and Senovilla, continue to hold for Lorentzian metrics that are of C 1,1-regularity.

Penrose–Hawking singularity theorems. The Penrose–Hawking singularity theoremsare a set of results in general relativity which attempt to answer the question of when gravitation produces singularities. Roughly speaking, it says that if there is only gravity and no antigravity, then tracing the universe backwards in time there is no way to stop it from crunching down to zero size. .

Penrose–Hawking singularity theorems. “Furthermore, the Penrose-Hawking singularity theorems demonstrate that the occurrence of these singularities is an intrinsic property built into the structure of classical general relativity. There are several different singularity theorems, pioneered by Hawking and Penrose. Related topics. Penrose–Hawking singularity theorems Last updated January 14, 2020.

We formulate appropriate weak versions of the strong energy condition and genericity condition for C 1,1-metrics, and of C 0-trapped submanifolds.
