Comments on cosmic censorship in AdS/CFT.

Hubeny, V. E. and Liu, X. and Rangamani, M. and Shenker, S. (2004) 'Comments on cosmic censorship in AdS/CFT.', Journal of high energy physics., 12 . 067.

Abstract

Recently Hertog, Horowitz, and Maeda (HHM) [14] have proposed that cosmic censorship can be violated in the AdS/CFT context. They argue that for certain initial data there is insufficient energy available to make a black hole whose horizon is big enough to cloak the singularity that forms. We have investigated this proposal in the models HHM discuss and have thus far been unable to find initial data that provably satisfy this criterion, despite our development of an improved lower bound on the size of the singular region. This is consistent with recent numerical results [15]. For certain initial data, the energies of our configurations are not far above the lower bound on the requisite black hole mass, and so it is possible that in the exact time development naked singularities do form. We go on to argue that the finite radius cut-off AdS5 situation discussed by HHM displays instabilities when the full 10D theory is considered. We propose an AdS3 example that may well be free of this instability.
