摘要：

Over the entire history of the Universe it is possible that even the known physical constants are not truly constant. The fine-structure constant — which characterizes the strength of the attraction between electrons and photons — is predicted by some theories to vary over time. New data from quasar spectra provide an upper limit on such variation.
