Abstract
We present a cosmological model with good physical properties which is invariant not only under changes of the space and time coordinates bu t also under changes of an extra (Kaluza-Klein) coordinate related to rest mass. In frames where the latter is chosen to be constant we reco ver standard cosmology. In frames where it is chosen to be variable we obtain new astrophysical effects and gain insight into the nature of the big bang.
