    Interpretations of the accelerating universe
    (Astronomical Society of the Pacific, 2002-10-26) Narlikar, J. V.; Vishwakarma, R. G.; Burbidge, G.
    It is generally argued that the present cosmological observations support the accelerating models of the universe, as driven by the cosmological constant or `dark energy'. We argue here that an alternative model of the universe is possible which explains the current observations of the universe. We demonstrate this with a reinterpretation of the magnitude-redshift relation for Type Ia supernovae, since this was the test that gave a spurt to the current trend in favour of the cosmological constant.

    Empirical approach to cosmology
    (Springer, 1981-01-23) Narlikar, J. V.; Burbidge, G.
    A two-component model of the universe is proposed, based on the observations of discrete extragalactic sources and the microwave background radiation. The large scale dynamics of the universe is determined by the radiation component and it leads to a characteristic size of the universe of approximately 600,000 Mpc and an age of approximately one trillion years. The second component, that of matter, occurs in discrete sources which group together in super-superclusters of characteristic size approximately 6000 Mpc and age 10 billion yr. It is suggested that the Galaxy belongs to one of these super-superclusters and that observations of discrete sources are confined to this unit. A reasonable agreement with the cosmological tests is obtained on the assumption that the geometry within a typical super-supercluster is Euclidean and that the redshifts of galaxies arise from a Doppler effect due to motions originating in a local explosion which gave birth to the super-supercluster. Further observational checks on this model are proposed.
