Precursors see inside black holes

TL;DR

This paper proposes that in AdS/CFT correspondence, the boundary field theory encodes information about events inside black hole horizons due to the nonlocal nature of precursors.

Contribution

It introduces a novel perspective that boundary precursors can reveal interior black hole information, leveraging the global properties of event horizons.

Findings

Boundary precursors are nonlocal and encode interior black hole information.

The global nature of event horizons underpins the proposed information encoding.

The approach suggests new ways to understand black hole information paradox.

Abstract

We argue that, given the nonlocal nature of precursors in AdS/CFT correspondence, the boundary field theory contains information about events inside a black hole horizon. The essence of our proposal is sketched in figure 1, and relies on the global nature of event horizons.
