| Abstract: | A nonsingular, homogeneous, isotropic cosmological model with cosmological constant in flat space-time theory of gravitation
is studied. The second law of thermodynamics yields a nonexpanding (nonstationary) universe without entropy production. At
the beginning of the universe radiation, matter and vacuum energy given by the cosmological constant are zero and then emerge
from gravitational energy. In the course of time the energy of radiation and matter decrease whereas the vacuum energy increases
forever. Light emitted from a distant galaxy loses energy on his way to the observer producing the observed redshift. The
velocity of light in the past is greater than the present one. This may explain superluminal velocities but only for large
redshifts. The sum of the density parameters of matter, radiation and vacuum energy is a little greater than one. All the
matter can be baryonic. There is no age problem of the universe.
