Varying alpha

We review properties of cosmological theories for the variation of the fine structure ‘constant’. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that are consistent with time‐variation in the fine structure ‘constant’ s...

Description
Summary:We review properties of cosmological theories for the variation of the fine structure ‘constant’. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that are consistent with time‐variation in the fine structure ‘constant’ since a redshift of 3.5. Properties of cosmological theories for the variation of the fine structure ‘constant’ are reviewed. Some general features of the cosmological models are highlighted that exist in these theories with reference to recent quasar data that are consistent with time‐variation in the fine structure `constant' since a redshift of 3.5.
