The Planckian Conspiracy: String Theory and the Black Hole Information Paradox

TL;DR

This paper investigates whether string theory's perturbative S-matrix exhibits nonlocal effects necessary for resolving the black hole information paradox, exploring the compatibility of quantum theory with black hole physics.

Contribution

It analyzes the presence of nonlocal effects in string theory's perturbative S-matrix related to the black hole information paradox.

Findings

Nonlocal effects are examined within string theory's perturbative framework.

The results shed light on the compatibility of string theory with quantum information preservation.

Insights into the role of nonlocality in resolving the black hole information paradox.

Abstract

It has been argued that the consistency of quantum theory with black hole physics requires nonlocality not present in ordinary effective field theory. We examine the extent to which such nonlocal effects show up in the perturbative S-matrix of string theory.
