Abstract

The recent evidence for a cosmological evolution of the fine structure constant α=e²/ℏ 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.
