Abstract:
Hawking's
black hole information paradox arises when the formation and subsequent
evaporation of a black hole
is
examined in the context of quantum theory. It pits quantum mechanical unitarity against locality in spacetime
and
highlights
the incompatibility between the world view offered by general relativity and
that of quantum physics.
In a
gravity theory with a gauge theory dual, the paradox must be resolved in favor of unitary evolution.
The
challenge is then to implement unitarity on the
gravity side and a key issue, which is at the center
of the recent
debate on
firewalls, is whether this requires giving up the equivalence principle.
