A black hole firewall is a hypothetical phenomenon where an observer falling into a black hole encounters high-energy quanta at (or near) the event horizon.The "firewall" phenomenon was proposed in 2012 by physicists Ahmed Almheiri, Donald Marolf, Joseph Polchinski, and James Sully as a possible solution to an apparent inconsistency in black hole complementarity.

Further support dispelling the conclusions of the information paradox came with the holographic principle and the gauge/gravity duality of the AdS/CFT correspondence, that conclusively proved that even the life cycle of an AdS black hole is governed by a unitary matrix of the conformal field theory on the boundary of the spacetime.
