"Forget time"

TL;DR

This paper advocates for a timeless approach to quantum gravity, proposing a formalism where variables are treated relationally rather than through temporal evolution, challenging traditional notions of time in physics.

Contribution

It introduces a novel formalism that models mechanics as relations between variables, removing the fundamental role of time in classical and quantum descriptions of nature.

Findings

Supports a timeless framework for quantum gravity

Reformulates mechanics as a relation-based theory

Challenges traditional time-dependent models in physics

Abstract

Following a line of research that I have developed for several years, I argue that the best strategy for understanding quantum gravity is to build a picture of the physical world where the notion of time plays no role. I summarize here this point of view, explaining why I think that in a fundamental description of nature we must "forget time", and how this can be done in the classical and in the quantum theory. The idea is to develop a formalism that treats dependent and independent variables on the same footing. In short, I propose to interpret mechanics as a theory of relations between variables, rather than the theory of the evolution of variables in time.
