will address the question of whether naked singularities might occur in nature, and if so, what they would look like to an observer.

The reader is also invited to study a few other excellent reviews [@revi] on the subject of cosmic censorship, which have appeared in recent years. Some of these reviews emphasize aspects other than those presented here, and some arrive at conclusions on cosmic censorship other than those given here. I would also like to draw attention to an earlier review of mine on this topic, which is somewhat more detailed, though a little dated [@tps]. Also, for a detailed bibliography the reader is requested is look up this earlier review; the references in the present article are not exhaustive, and largely confined to the more recent papers.

Theoretical Evidence for the Formation of Black Holes and Naked Singularities
=============================================================================

We consider the gravitational collapse of physically reasonable classical matter, where by ‘physically reasonable’ is meant that the matter satisfies one or more of the energy conditions (weak energy condition, strong energy condition and the dominant energy condition). Also, most of the collapse studies that have been carried out so far deal with spherical collapse - even this
