A realist interpretation of quantum mechanics based on undecidability due to gravity

TL;DR

This paper discusses a novel interpretation of quantum mechanics rooted in undecidability caused by gravity, proposing solutions to the measurement problem and the problem of outcomes within quantum gravity frameworks.

Contribution

It introduces a realist interpretation based on gravity-induced undecidability, offering a new perspective on quantum measurement and the problem of outcomes.

Findings

Addresses the problem of time in quantum gravity

Proposes gravity-induced undecidability as a basis for quantum measurement

Resolves the problem of outcomes without relying on practical approximations

Abstract

We summarize several recent developments suggesting that solving the problem of time in quantum gravity leads to a solution of the measurement problem in quantum mechanics. This approach has been informally called "the Montevideo interpretation". In particular we discuss why definitions in this approach are not "for all practical purposes" (fapp) and how the problem of outcomes is resolved.
