Teleparallel Gravity: An Overview

TL;DR

This paper provides an overview of teleparallel gravity, detailing its fundamental principles, field equations, energy-momentum concepts, and the role of torsion as an alternative to curvature in describing gravitation.

Contribution

It offers a comprehensive review of the teleparallel equivalent of general relativity, highlighting its main properties and differences from standard general relativity.

Findings

Teleparallel gravity uses torsion instead of curvature to describe gravity.

The paper discusses the energy-momentum density for the gravitational field.

It compares the roles of torsion and curvature in gravitational theories.

Abstract

The fundamentals of the teleparallel equivalent of general relativity are presented, and its main properties described. In particular, the field equations, the definition of an energy--momentum density for the gravitational field, the teleparallel version of the equivalence principle, and the dynamical role played by torsion as compared to the corresponding role played by curvature in general relativity, are discussed in some details.
