Relative changes with redshift of the fine structure constant
The UVES measurement values of the relative change of the fine structure constant alpha from the sample of absorption systems, plotted as a function of the redshift and the corresponding look-back time. The open circle is the measurement from the Oklo natural reactor (near Gabon, West Africa). The horizontal long dashed lines show the area of the previous claim of variation of the fine structure constant. Clearly, the UVES data are inconsistent with this range.
