Query: Transparentizing Black Holes to Eternal Traversable Wormholes   We present the gravity description of evaporating black holes that end up
with eternal traversable wormholes where every would-be behind horizon degree
is available in asymptotic regions. The transition is explicitly realized by a
time-dependent bulk solution in the two-dimensional Einstein-dilaton gravity.
In this solution, the initial AdS$_2$ black hole is evolved into an eternal
traversable wormhole free of any singularity, which may be dubbed as
transparentization of black holes to eternal traversable wormholes. The bulk
construction completely matches with the boundary description governed by the
Schwarzian boundary theory. We also obtain solutions describing eternal
traversable wormholes as well as excitations by an additional matter and
graviton oscillations on eternal traversable wormholes, which show that the
eternal traversable wormhole states are gapped and non-chaotic. Embedding the
2d solution into a 4d traversable wormhole connecting two magnetically charged
holes, we discuss 4d scattering of a wave incident upon one end of the
traversable wormhole.
