cosmic censorship hypothesis

[′käz·mik ′sen·sər‚ship hī‚päth·ə·səs]
(astronomy)
The hypothesis that a system which evolves according to the equations of general relativity from an initial state that does not have singularities or any unusual properties will not develop any space-time singularities that would be visible from large distances.

The "cosmic censorship conjecture" - a term used to refer to the screening effect of the event horizon - will ensure that the singularity has no effect outside the black hole, and general relativity will therefore still be valid there.
I discuss some of the theoretical and experimental infrastructure required to make a conclusive test of the cosmic censorship and causality conjectures on which these theorems are based.
He begins by reviewing the background from the theory of partial differential equations and in geometry, global hyperbolicity, and uniqueness before moving on to general relativity and then pathologies and strong cosmic censorship. A sampling of more detailed topics turns up functional analysis, symmetric hyperbolic systems, characterizations of global hyperbolicity, local existence, constant mean curvature, and asymptotic behavior.
Again, 'cosmic censorship' is a name that refers to a variety of different topics.
For example, he includes such terms as "free lunch universe" and "cosmic censorship," topics in cosmology that often spark great debate among astronomers and sometimes catch the public eye.
In 1969, mathematical physicist Roger Penrose of Oxford University in England enshrined this idea in his "cosmic censorship" hypothesis, stating that singularities would always be found inside black holes.
If the findings of the study are to be believed, it would seem that (http://astronomy.swin.edu.au/cosmos/C/Cosmic+Censorship+Conjecture) Roger Penrose's cosmic censorship conjecture , which basically states that no imploding object can ever give rise to a naked singularity, is true.
Penrose proposed a Cosmic Censorship Conjecture (CCC) [3-5] to forbid the occurrence of naked singularities in a solution of the field equations.
That question, in turn, raises deep, ill-understood issues about cosmic censorship, quantum gravity and quantum field theory.
