The spacetime metric in particle QED

TL;DR

This paper proposes that spacetime curvature emerges from particle interactions in QED, suggesting that the Minkowski metric is perturbed during measurement, leading to a connection with Einstein's equations.

Contribution

It introduces a model where spacetime geometry arises from particle interactions, linking quantum electrodynamics with general relativity through emergent spacetime.

Findings

Minkowski metric is perturbed during physical measurement.

Emergent spacetime from particle interactions aligns with Einstein's equations.

Small time delays in interactions can remove divergences in QED.

Abstract

A small time delay between interactions, which has previously been shown to remove divergences from QED, is used to show that, if spacetime geometry is emergent from particle interactions in the manner suggested by Bondi, then Minkowski metric, which appears in the Schroedinger equation as a requirement of the probability interpretation, is perturbed in physical measurement, leading to curved spacetime in accordance with Einstein's equation.
