What kind of noncommutative geometry for quantum gravity ?
Pierre Martinetti
TL;DR
This paper discusses the application of noncommutative geometry to quantum gravity, reviewing its role in the standard model and exploring the thermal time hypothesis, while questioning their relevance for quantum gravity.
Contribution
It provides a concise overview of noncommutative geometry's role in the standard model and examines the thermal time hypothesis in the context of quantum gravity.
Findings
Noncommutative geometry describes the standard model effectively.
The thermal time hypothesis offers a novel perspective on time in quantum gravity.
The relevance of these approaches for quantum gravity remains uncertain.
Abstract
We give a brief account of the description of the standard model in noncommutative geometry as well as the thermal time hypothesis, questioning their relevance for quantum gravity.
