DESCRIPTION:Black hole singularities leave distinct imprints on holographi
 c correlators\, traceable to bouncing geodesics: null geodesics that begin
  on one boundary of an eternal AdS black hole\, reflect off the singularit
 y\, and reach the opposite boundary. Using the Operator Product Expansion 
 (OPE)\, I will show that singularities in the stress-tensor sector of the 
 holographic correlator occur precisely at positions predicted by these geo
 desics\, establishing a direct connection between black hole singularities
  and the analytic structure of holographic correlators. I will also discus
 s how complexified geodesics—crucial for capturing the full correlator
 —correspond to contributions from double-trace operators in the CFT. If 
 time permits\, I will outline ongoing extensions to charged black holes\, 
 whose richer causal structure offers new insights into these holographic s
 ignatures.
