Cosmological observations and spectroscopic studies continually test and support the principle that fundamental physical laws remain uniform across different galaxies and cosmic epochs.

The analysis

The claim states that physical laws remain uniform across different galaxies as verified by cosmological observations. Papers 1 and 4 directly discuss methods and observational constraints (using quasar absorption spectra, atomic clocks, and high-precision spectroscopy) used to test the universality and constancy of physical laws on a cosmological scale, thus supporting the claim.
