The Accelerating Expansion of the Universe and Torsion Energy

TL;DR

This paper proposes a geometric approach using a version of Absolute Parallelism geometry with both curvature and torsion to explain the universe's accelerating expansion, attributing repulsive effects to torsion energy.

Contribution

It introduces a novel geometric framework incorporating torsion to account for cosmic acceleration, extending Einstein's geometrization philosophy.

Findings

Torsion energy produces a repulsive force in the universe.

A fine-tuning parameter aligns the model with observed acceleration.

Curvature energy results in an attractive force, balancing the effects.

Abstract

In the present work, it is shown that the problem of the accelerating expansion of the Universe can be directly solved by applying Einstein geometrization philosophy in a wider geometry. The geometric structure used to fulfil the aim of the work is a version of Absolute Parallelism geometry in which curvature and torsion are simultaneously non vanishing objects. It is shown that, while the energy corresponding to the curvature of space- time gives rise to an attractive force, the energy corresponding to the torsion indicates the presence of a repulsive force. A fine tuning parameter can be adjusted to give the observed phenomena.
