Negative energies and time reversal in Quantum Field Theory

TL;DR

This paper reviews the concept of negative energies in Quantum Field Theory, discussing their theoretical and phenomenological aspects, and suggests that their full integration may require a modified general relativistic framework.

Contribution

It provides a comprehensive review of negative energies in QFT and proposes a potential pathway for their rehabilitation within a modified general relativistic model.

Findings

Negative energies are conceptually reviewed in QFT.

Rehabilitation of negative energies may need modified general relativity.

The paper discusses both theoretical and phenomenological perspectives.

Abstract

The theoretical and phenomenological status of negative energies is reviewed in Quantum Field theory leading to the conclusion that hopefully their rehabilitation might only be completed in a modified general relativistic model
