A Model of Varying Fine Structure Constant and Varying Speed of Light

TL;DR

This paper proposes a cosmological model where only the speed of light varies to explain observed changes in the fine structure constant, fitting spectral data and addressing initial value problems in cosmology.

Contribution

It introduces a novel model linking varying speed of light to changes in the fine structure constant, providing a new approach to cosmological evolution.

Findings

Model fits quasar spectral line data

Provides solutions to initial value problems in cosmology

Suggests a varying speed of light as an explanation for  evolution

Abstract

The recent evidence for a cosmological evolution of the fine structure constant \alpha=e^2/\hbar c found from an analysis of absorption systems in the spectra of distant quasars, is modelled by a cosmological scenario in which it is assumed that only the speed of light varies. The model fits the spectral line data and can also lead to a solution of the initial value problems in cosmology.
