Cool horizons for entangled black holes

TL;DR

This paper explores the connection between entangled black holes and wormholes, proposing that entanglement may universally give rise to geometric bridges, which could resolve paradoxes like the firewall paradox.

Contribution

It extends the concept of Einstein-Rosen bridges to more general entangled states, suggesting a broader link between entanglement and spacetime geometry.

Findings

Entangled black holes can be connected via wormholes.

The approach offers potential resolutions to firewall paradoxes.

Entanglement may universally correspond to geometric bridges.

Abstract

General relativity contains solutions in which two distant black holes are connected through the interior via a wormhole, or Einstein-Rosen bridge. These solutions can be interpreted as maximally entangled states of two black holes that form a complex EPR pair. We suggest that similar bridges might be present for more general entangled states. In the case of entangled black holes one can formulate versions of the AMPS(S) paradoxes and resolve them. This suggests possible resolutions of the firewall paradoxes for more general situations.
