Within a fundamental quantum theory, in which gravitation is described by magnetic binding of hadron-lepton pairs, the mechanisms responsible to the development of the universe are well understood. The Solar system has been found to be a stable bound state with a present distance from the center of the universe of about 1200 Mpc. Using this result, the radius of the universe, which comprises essentially all matter, is estimated to be about 1800 Mpc. The total mass is given by the accumulated mass, before the early gravitational system became destabilized by CP-violating processes. Consistent with the known energy-density of the universe a mass of about 4 10^{78} GeV/c^2 (sim 4 10^{21} Solar masses) is obtained.
Further, from the present temperature of the cosmic microwave background (CMB) of 2.73 K an annihilation radius in the order of 1 mm is obtained (for absorption of a fraction of 10^{-4} and 10^{-5} of the total annihilation energy)
