Can the Equivalence Principle Survive Quantization?

TL;DR

This paper proposes a generalized approach to Einstein gravity that remains consistent after renormalization, suggesting a candidate for quantum gravity where all matter interacts with gravity uniformly.

Contribution

It introduces a novel generalized framework that results in Einstein gravity post-renormalization, implying a unified treatment of matter in quantum gravity.

Findings

Einstein gravity can be derived after renormalization in the proposed approach.

The approach treats all matter equally in gravitational interactions.

It offers a candidate theory for quantum gravity consistent with the equivalence principle.

Abstract

It is well known that Einstein gravity is non-renormalizable; however a generalized approach is proposed that leads to Einstein gravity {\it after} renormalization. This them implies that at least one candidate for quantum gravity treats all matter on an equal footing with regard to the gravitational behaviour.
