review text: We show that a self-similar general relativistic spherical collapse of a perfect fluid with an adiabatic equation of state \(p=(\gamma -1)\rho\) and low enough \(\gamma\) 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.
