On Dark Energy and Accelerated Reference Frames

TL;DR

This paper proposes that the accelerated expansion of the Universe, typically attributed to dark energy, can be explained as a manifestation of torsion in Teleparallel gravity within a flat universe, offering an alternative perspective.

Contribution

It introduces a torsion-based explanation for cosmic acceleration in a flat universe, challenging the dark energy paradigm using Teleparallel gravity theory.

Findings

Acceleration can be expressed via Hubble's Law and torsion tensor.

The model relates acceleration to the deceleration parameter and Hubble's constant.

The approach provides an alternative interpretation of cosmic acceleration.

Abstract

The paper is devoted to an explanation of the accelerated rate of expansion of the Universe. Usually the acceleration of the Universe, which is described by FRW metric, is due to dark energy. It is shown that this effect may be considered as a manifestation of torsion tensor for a flat Universe in the realm of Teleparallel gravity. An observer with radial field velocity obey Hubble's Law. As a consequence it is established that this is radial acceleration in a flat Universe. In Eq. (\ref{24}) the acceleration is written in terms of the deceleration parameter, the Hubble's constant and the proper distance. This may be interpreted as an acceleration of the Universe.
