In our previous works about the hydrodynamics of the dark superfluid (dark energy + dark matter) we have addressed issues concerning particle physics, nature and propagation of light, quantum gravity and relativity. Here we want to test the convenience of a cosmological model based on such a dark superfluid. We obtain a solution to the cosmological redshift that matches the set of available data , including distant supernovae, without resorting to an expanding universe. The correct redshift seems to be due to the density of the dark superfluid fading out over large distances in a spherical distribution. The model seems also suitable to solve baryon asymmetry and to let us better understand the nature of dark energy and of light itself. Still critical issues as the Big Bang, cosmic inflation and accelerated expansion of the universe would vanish, opening up new prospects.
