Theoretical modeling demonstrates tight constraints on quintessence potentials in varying-constant cosmologies, suggesting detectable weak equivalence principle violations.
If the reported measurements of the time variation of the fine structure constant from observations of distant QSOs are correct, combined with the Oklo limit, they would strongly constrain the class of the quintessence potential. If these results prove valid, future satellite experiments (STEP) should measure the induced violation of the weak equivalence principle. Future cosmological observations of nearby (z ≲ 0.5) absorption systems would make it clear whether the variation is significant or not.
