如果报道的来自遥远类星体观测的精细结构常数随时间变化的测量是正确的，再加上Oklo极限，它们将强烈限制精华子势的类别。如果这些结果被证明是有效的，未来的卫星实验(STEP)应该测量引起的对弱等效原则的违反。未来对附近的$(z Siml 0.5)$吸收系统的宇宙学观测将清楚地表明这种变化是否显著。
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 experiment (STEP) should measure the induced violation of the weak equivalence principle. Future cosmological observations of nearby $(z siml 0.5)$ absorption systems would make it clear whether the variation is significant or not.
