Gravity can be neither classical nor quantized

TL;DR

This paper proposes that gravity can fundamentally be neither classical nor quantized, challenging the common assumption and suggesting a new approach to reconcile quantum field theories with general relativity.

Contribution

It introduces the concept of a gravity theory that is neither classical nor quantized, offering a novel perspective to unify quantum mechanics and gravity.

Findings

A theory of gravity that is neither classical nor quantized is possible.

Such a theory could resolve tensions between quantum field theories and general relativity.

The proposed approach challenges traditional assumptions about the nature of gravity.

Abstract

I argue that it is possible for a theory to be neither quantized nor classical. We should therefore give up the assumption that the fundamental theory which describes gravity at shortest distances must either be quantized, or quantization must emerge from a fundamentally classical theory. To illustrate my point I will discuss an example for a theory that is neither classical nor quantized, and argue that it has the potential to resolve the tensions between the quantum field theories of the standard model and general relativity.
