Linking the trans-Planckian and the information loss problems in black hole physics

TL;DR

This paper argues that the trans-Planckian problem and the information loss problem in black hole physics are fundamentally connected, both arising from the perspective of general relativity as an effective field theory.

Contribution

It provides a unified perspective linking two major black hole paradoxes, emphasizing their common origin in the effective field theory approach to gravity.

Findings

Trans-Planckian and information loss problems are interconnected.

Understanding these issues requires viewing general relativity as an effective field theory.

The paper offers a conceptual framework linking the two problems.

Abstract

The trans-Planckian and information loss problems are usually discussed in the literature as separate issues concerning the nature of Hawking radiation. Here we instead argue that they are intimately linked, and can be understood as "two sides of the same coin" once it is accepted that general relativity is an effective field theory.
