Abstract

We show that a self-similar general relativistic spherical collapse of a perfect fluid with an adiabatic equation of state p=(γ-1)ρ{variant} and low enough γ values, results in a naked singularity. The singularity is tangent to an event horizon which surrounds a massive singularity and the redshift along a null geodesic from the singularity to an external observer is infinite. We believe that this is the most serious counter example to cosmic censorship obtained so far.
