Which is incorrect, the theory of stellar pulsation or the theory of stellar evolution?
>When Cepheids are used as indicators for the distances to nearby galaxies, a necessary assumption is that mass is invariant throughout the universe. But if mass varies with charge, each galaxy—and therefore each star in it—could have a different charge distribution with respect to the intergalactic plasma. Each galaxy could have an idiosyncratic period-luminosity relationship for Cepheids, rendering them unusable for determining distances to other galaxies.
