Torsion, an alternative to dark matter?

TL;DR

This paper explores Einstein-Cartan's theory as an alternative explanation to dark matter by testing its predictions against supernovae data, finding it potentially compatible with current observations.

Contribution

It introduces Einstein-Cartan's theory as a viable alternative to dark matter and tests its consistency with supernovae observations.

Findings

Einstein-Cartan theory can fit supernovae data

Dark matter alternative is compatible with current observations

Supports revisiting torsion-based gravity models

Abstract

We confront Einstein-Cartan's theory with the Hubble diagram. An affirmative answer to the question in the title is compatible with today's supernovae data.
