Black hole information paradox (part two)

When particles escape from a black hole via Hawking radiation, they only contain information on the mass, spin and charge of the black hole’s original material. Other information, that is needed to reconstruct the black hole’s past, seems to be lost permanently. This breaks the fundamental principle of unitarity which says that total information must be conserved, creating a paradox. 

This episode, we’ll examine potential solutions to the paradox, with particular focus on AdS/CFT correspondence (ie. the holographic principle) and recent work by Ahmed Almheiri.
