THE OSCILLATING G-MODEL - A POSSIBLE EXPLANATION FOR THE NATURE OF COSMOLOGICAL NONBARYONIC MATTER

We show that the oscillating G model proposed as an explanation of the periodic distribution in the galaxy-count number is also an acceptabl e model for the cosmological nonbaryonic matter when taken together wi th the standard inflationary scenario (Omega = 1). The model, and in p articular the value of the galactic redshift oscillation amplitude, is compatible with the values of the baryonic energy density Omega(bar) allowed by the primordial abundance of light elements (0.010 less than or equal to Omega h(2) less than or equal to 0.020). Remarkably, thes e values also result in a value for the age of the universe compatible with recent observations. Specifically, the lower bound of 11.5 Gyr i s satisfied provided the Hubble parameter is given by H-0 = h 100 km s (-1) Mpc(-1) with h < 0.68.
