Cosmic Censorship Hypothesis
The weak and the strong cosmic censorship hypotheses are two mathematical conjectures about the structure of singularities arising in general relativity.
Singularities that arise in the solutions of Einstein's equations are typically hidden within event horizons, and therefore cannot be seen from the rest of spacetime. Singularities which are not so hidden are called naked. The weak cosmic censorship hypothesis conjectures that no naked singularities other than the Big Bang singularity exist in the universe. The hypothesis was conceived by Roger Penrose in 1969. Cosmic censorship hypotheses should be distinguished from chronological censorship under which every closed timelike curve passes through an event horizon, which might prevent an observer from detecting the causal violation.

Famous quotes containing the words cosmic, censorship and/or hypothesis:
“Unless they are immediate victims, the majority of mankind behaves as if war was an act of God which could not be prevented; or they behave as if war elsewhere was none of their business. It would be a bitter cosmic joke if we destroy ourselves due to atrophy of the imagination.”
—Martha Gellhorn (b. 1908)
“The censorship method ... is that of handing the job over to some frail and erring mortal man, and making him omnipotent on the assumption that his official status will make him infallible and omniscient.”
—George Bernard Shaw (1856–1950)
“On pragmatistic principles, if the hypothesis of God works satisfactorily in the widest sense of the word, it is true.”
—William James (1842–1910)
