the spherical case, very little is known about gravitational collapse and cosmic censorship for non-spherical systems.

Properties of Naked Singularities
---------------------------------

There are now sufficiently many known examples of naked singularities for one to enquire about properties of such singularities. It may be that there are well-defined laws of ‘naked singularity mechanics’, just as there are the laws of black hole mechanics (though there is no indication at the moment that such a thing is true). At present there is only some scattered knowledge about properties like curvature strength, stability of the Cauchy horizon and redshift.

Examples of both weak curvature and strong curvature naked singularities have been found [@tps]. While spacetime cannot be extended through the latter kind of singularity, it may possibly be extendible through a weak singularity. For a discussion of extendibility see Clarke [@cl].

If the Cauchy horizon accompanying a naked singularity were to be unstable, that could be evidence in favour of cosmic censorship. However, examples of stable as well as unstable Cauchy horizons are known in classical collapse. (See Penrose [@revi] for some more discussion on Cauchy horizon stability).

The redshift of the null rays emanating from a singularity can be shown to be
