TL;DR
This paper reviews how boundary CFT correlators in AdS/CFT encode subtle signals of the black hole singularity behind the horizon.
Contribution
It highlights the potential of boundary correlators to reveal information about the black hole singularity within the AdS/CFT framework.
Findings
CFT correlators contain signals of the black hole singularity.
These signals are subtle but potentially detectable.
The review clarifies the relationship between bulk singularities and boundary data.
Abstract
We present a short review of hep-th/0306170. In the context of AdS/CFT correspondence, we explore what information from behind the horizon of the bulk black hole geometry can be found in boundary CFT correlators. In particular, we argue that the CFT correlators contain distinct, albeit subtle, signals of the black hole singularity.
