Many spacetimes in General Relativity can present naked singularities
which physical interpretation is a notable challenge. The cosmic
censorship conjecture states basically that, in physically reasonable
conditions, any spacetime singularity must be covered by an event
horizon, i.e., naked singularities should not exist. However, for wave
phenomena, some naked singularities are effectively harmless due to
the self-adjointness properties of their governing equations. These
results suggest that the cosmic censorship conjecture might be weaker
for wave phenomena than the typical geodesic formulation.
