Cosmic Time Dilation
Abstract
The observed apparent time dilation of supernovae light curves claimed recently by Leibundgut et al. to establish directly the ``expansion of the universe'' is, rather, a general implication of fundamental physics. In particular, it applies to chronometric cosmology, in which it appears explicitly as a generalized Lorentz-Fitzgerald contraction. The dilation effect was earlier shown in the proper motion-to-redshift relation of superluminal sources, as analyzed in the frame of chronometric cosmology by Segal, providing an estimate of the cosmic distance scale.
