We critically review the current null results on a varying fine-structure constant, a, derived from Very Large Telescope (VLT)/Ultraviolet and Visual Echelle Spectrograph (UVES) quasar absorption spectra, focusing primarily on the many-multiplet analysis of 23 absorbers from which Chand et al. reported a weighted mean relative variation of Aa/a = (-0.06 ± 0.06) x 10 -5 . Our analysis of the same reduced data, using the same fits to the absorption profiles, yields very different individual… Expand
