Abstract

We argue that models in which an observable variation of the fine structure constant is explained by motion of a cosmic scalar field, are not stable under renormalization, and require massive fine tuning that cannot be explained by any known mechanism.

    • Would you really characterize this Wilczynska, Webb, King et al. paper as an argument that there is "growing evidence", rather than (say) that it's a number-crunching argument that the small amount of observations that suggested a dipole variation to Webb et al. (and King et…
