# In Search of the Spacetime Torsion

## TL;DR

This paper reviews theoretical possibilities and experimental considerations regarding the role of spacetime torsion in gravity, highlighting the challenges in detecting it due to interpretational ambiguities.

## Contribution

It analyzes two different theoretical approaches to spacetime torsion and discusses their experimental implications, providing a comparative perspective.

## Key findings

- Torsion's role in gravity remains experimentally unconfirmed.
- Different interpretations of torsion lead to varied experimental predictions.
- The paper discusses the consistency of two torsion models.

## Abstract

Whether torsion plays or not a role in the description of the gravitational interaction is a problem that can only be solved by experiment. This is, however, a difficult task: since there are different possible interpretations for torsion, there is no a model-independent way to look for it. In these notes, two different possibilities will be reviewed, their consistency analyzed, and the corresponding experimental outputs briefly discussed.
