Naked singularity

A naked singularity in general relativity, a gravitational singularity, ie a hypothetical point in space-time with the strongest, possibly infinite curvature, but this is in contrast to a black hole is not surrounded by an event horizon.

The question of whether naked singularities also occur in nature, is used by Roger Penrose in the adoption of a Noumenons, which he calls " cosmic censor ", denied. Stephen Hawking lost a bet on this question as a computer simulation proved its possibility by assuming negative energy. The existence of such singularities would mean that it would be possible to observe a perfect gravitational collapse. Recent computer simulations suggest, however, that black holes would its event horizon is maintained even in the event of a collision with another black hole, which might argue forecast for Roger Penrose. Also there is no evidence for the existence of naked astronomical singularities. At George Ellis However, they are part of his alternative physical world view and according to the standard model of cosmology the Big Bang can be seen as a naked singularity.
