# Conditions for strong cosmic censorship to apply

ergospherical
In a podcast with Sean Carroll and Roger Penrose (link :) ), it's briefly discussed that one can cook up certain unphysical examples of spacetimes in which SCC is violated. Indeed, in Harvey Reall's BH notes (link), it's written that:
Strong cosmic censorship conjecture (Penrose). Let (##\Sigma_{ab}, h_{ab}, K_{ab}##) be a geodesically complete, asymptotically flat (with ##N## ends), initial data set for the vacuum Einstein equation. Then generically the maximal Cauchy development of this initial data is inextendible... The word ”generically” is included because of known counter-examples...
What is a sufficient set of restrictions required in order for SCC to hold (if any)?

It seems that you would need the conjecture to be resolved first in order to know if the conditions are sufficient.
