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:
“The furthest bodies
To which man sends his
Speculation,
Beyond which God is;
The cosmic motes
Of yawning lenses.”
—Robert Frost (1874–1963)
“... a phallocentric culture is more likely to begin its censorship purges with books on pelvic self-examination for women or books containing lyrical paeans to lesbianism than with See Him Tear and Kill Her or similar Mickey-Spillanesque titles.”
—Robin Morgan (b. 1941)
“Oversimplified, Mercier’s Hypothesis would run like this: “Wit is always absurd and true, humor absurd and untrue.””
—Vivian Mercier (b. 1919)
