Naked singularity

A naked singularity is a singularity without an event horizon. In other words, it is a point in space in which general relativity predicts would have infinite density which is observable from the outside. The theoretical existence of naked singularities are important because their existence would mean that it would be possible to observe the collapse of an object to infinite density.

Computer simulations of the collapse of a disk of dust have indicated that these objects can exist and thus the [Cosmic censorship principle]? does not hold. The existence or non-existence of naked singularities was a bet that Stephen Hawking who bet no, lost.
