AMPS firewall paradox

E590887

The AMPS firewall paradox is a theoretical puzzle in black hole physics proposing that an energetic "firewall" at the event horizon may be required to preserve quantum unitarity, challenging the traditional view that crossing the horizon is physically uneventful.

coreClaim an energetic firewall may exist at or near the event horizon of an old black hole
the assumptions of unitarity, local quantum field theory, and a smooth horizon are mutually inconsistent for old black holes
