# The black hole firewall problem

## Idea

In AMPS 2012, it is proposed that infalling observers encounter a “firewall” at (or just outside) the event horizon of a black hole. This is part of an attempted resolution of the black hole information paradox.

For a rough summary, see Wikipedia for now.

The suggestion that there is a black hole “firewall” phenomenon originates in

A systematic analysis of the (non-)phenomenon using actual computations in AdS-CFT duality is in

whose authors say in their introduction:

These $[$BH firewall$]$ proposals originate not from direct calculations in quantum gravity, $[$$]$ While quantum gravity is a mysterious subject, the AdS-CFT correspondence provides us with a setting where we can examine these ideas within a perfectly well defined theory.

A useful comment on that article is in

In the course of this debate, the following article proposed that there is a close relaiton between wormholes (Einstein-Rosen bridges) and quantum entanglement (Einstein-Podolsky-Rosen phenomenon), now known as “ER = EPR”
