Query: Energy condition and cosmic censorship conjecture in the perfect fluid
  collapse   The hypothesis of cosmic censorship plays a crucial role in classical general
relativity, namely, to ensure that naked singularities would never occur from
the black hole singularity. In this paper, we will present how energy
conditions prohibit forming the naked singularity in the spherical perfect
fluid collapse, and thus the strong cosmic censorship conjecture hold in this
model. We also show that this result can be extended to the cosmological
constant background.
