A universe consisting of a nonrotating, perfect fluid is defined analytically to have streamlines (light) which follow geodesic lines of a particular metric. The model permits derivation of a new absolute time scale over which the evolution of the universe can be traced. The universe described experienced three phases: when the density exceeded a nuclear density; when radiation dominated; and when grains dominated. Equations of state are developed for the two latter phases. The implications of the models for the interpretation of observational data such as the red shifts of galaxies and the 3 K background are discussed.
