Abstract |
I will review recent progress on the black hole information puzzle involving the
appearance of "islands" in the black hole interior. The islands arise from the
replica trick used to calculate the entropy of Hawking radiation. This entropy
receives large non-perturbative corrections from gravitational instantons called
replica wormholes, which connect multiple copies of the black hole through the
interiors. In several toy models where these contributions can be calculated
explicitly, the resulting entropy is consistent with unitary black hole
evaporation. |
