Echoes of Love Beyond the Horizon: A Bridge to Recovering Information from Black Holes

TL;DR

This paper suggests that quantum gravitational effects can preserve and potentially recover information from black holes by revealing internal structures and correlations in Hawking radiation, challenging traditional views on black hole information loss.

Contribution

It introduces the concept of quantum hair via non-zero tidal Love numbers, linking quantum gravity effects to black hole internal structure and information recovery mechanisms.

Findings

Black holes acquire quantum hair due to quantum gravity effects.

Tidal Love numbers are Planck-scale suppressed, affecting late-stage evaporation.

Information may be recovered through Hawking radiation correlations or remnants.

Abstract

We provide further evidence that information is preserved during black hole evaporation and may be recoverable, provided quantum gravitational effects resolve the singularity. We demonstrate that due to quantum gravity effects, black holes acquire quantum hair, manifested by non-zero tidal Love numbers, revealing a distinct internal structure similar to neutron stars. Interestingly, the magnitude of these Love numbers is Planck-scale suppressed, implying significant tidal deformation in the late stage of evaporation. Depending on the final state of the black hole, information may be retrieved through correlations in Hawking radiation, baby universes, or via remnants.
