Cosmic Censorship Hypothesis

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)

    ... censorship often boils down to some male judges getting to read a lot of dirty books—with one hand.
    Robin Morgan (b. 1941)

    It is more than likely that the brain itself is, in origin and development, only a sort of great clot of genital fluid held in suspense or reserved.... This hypothesis ... would explain the enormous content of the brain as a maker or presenter of images.
    Ezra Pound (1885–1972)
