A model with pressure is proposed which is linearly expanding and which is an exact solution of Einstein’s field equations. The recession velocity of the galaxies of this model never exceeds the speed of light. The model is closely related to the Rh=ct model of Melia, which is flat and infinite. However, our subluminal model is spatially positively curved and closed. Nevertheless all data from observations gathered and surveyed by Melia support our model.
