NONSINGULAR COSMOLOGICAL MODEL WITH BACKGROUND FIELD IN FLAT SPACE-TIME THEORY OF GRAVITATION

A previously studied theory of gravitation in flat space-time is appli ed to homogeneous, isotropic cosmological models. In addition to radia tion a two-component fluid model consisting of dust and of a backgroun d field is studied. This universe starts from a nonsingular state and expands for ever. The energy of radiation, of dust and of the backgrou nd are emerged from the gravitational energy. Entropy is produced. The age of the universe is infinite measured in units of absolute time wh ereas the proper-time of the universe is finite. The sum of the densit y parameters of dust, of radiation and of the background field is abou t one. There is no flatness and no monopole problem.
