General relativity, torsion, and quantum theory

TL;DR

This paper explores how incorporating torsion into gravitational theories might bridge the gap between general relativity and quantum mechanics, proposing that torsion-inclusive models could unify these fundamental theories.

Contribution

It suggests that theories with torsion could offer new insights into quantum gravity and discusses how Dirac and Einstein equations might emerge as limits of such theories.

Findings

Torsion-inclusive gravity theories may better unify quantum mechanics and general relativity.

Speculation on Dirac and Einstein equations as limiting cases of torsion-based gravity.

Potential for torsion to resolve obstacles in quantum gravity reconciliation.

Abstract

We recall some of the obstacles which arise when one tries to reconcile the general theory of relativity with quantum theory. We consider the possibility that gravitation theories which include torsion, and not only curvature, provide better insight into a quantum theory of gravity. We speculate on how the Dirac equation and Einstein gravity could be thought of as limiting cases of a gravitation theory which possesses torsion.
