This paper introduces TQG, a new formalism for quantum gravity based on non-commutative tori, offering insights into the nature of time, including its discretization and solutions to longstanding problems.

Contribution

It presents a novel formalism called TQG that advances understanding of time in quantum gravity using non-commutative geometry.

Findings

Time is discretized in the TQG formalism

TQG provides a solution to the Problem of Time

Connections are made between time, measurement, and wave function collapse

Abstract

As a continuation to [12], we introduce a new formalism for (part of) QG, which we call TQG, since it's based on the NC Tori. This allows us to obtain numerous insights about the nature of time, like its discretization, its regular pace at the macroscopic scale, a solution to the Problem of Time, and a connection with the Measurement Problem and wave function collapse.
