Distinguishing causal time from Minkowski time and a model for the black hole quantum eigenstates

TL;DR

The paper explores the concept of black hole complementarity, proposing a model that distinguishes causal time from Minkowski time and offers a new perspective on black hole quantum states, potentially challenging classical relativity.

Contribution

It introduces a novel model for black hole atmospheres based on multiple time sheets, providing a framework for understanding black hole quantum states beyond traditional relativity.

Findings

Stress-energy tensor differs between outside and ingoing observers

Proposes a new model for black hole atmosphere

Suggests a dynamical description of black hole quantum states

Abstract

A discussion is presented of the principle of black hole com- plementarity. It is argued that this principle could be viewed as a breakdown of general relativity, or alternatively, as the introduction of a time variable with multiple `sheets' or `branches' A consequence of the theory is that the stress-energy tensor as viewed by an outside observer is not simply the Lorentz-transform of the tensor viewed by an ingoing observer. This can serve as a justification of a new model for the black hole atmosphere, recently re-introduced. It is discussed how such a model may lead to a dynamical description of the black hole quantum states.
