Can we observationally test the weak cosmic censorship conjecture?

Understand

In general relativity, gravitational collapse of matter fields ends with the formation of a spacetime singularity, where the matter density becomes infinite and standard physics breaks down.

• According to the weak cosmic censorship conjecture, singularities produced in the gravitational collapse cannot be seen by distant observers and must be hidden within black holes.
• The validity of this conjecture is still controversial and at present we cannot exclude that naked singularities can be created in our Universe from regular initial data.
• In this paper, we study the radiation emitted by a collapsing cloud of dust and check whether it is possible to distinguish the birth of a black hole from the one of a naked singularity.
