PLASMA COSMOLOGY.

Abstract

The author has reviewed Klein's cosmology, which is based on Dirac's matter-antimatter symmetry. Its initial and highly questionable phase is a contraction of an extremely large volume of matter-antimatter. Anihilation increases very rapidly with contraction, and when a size on the order of 10**2**5 m (1 giga-light year) is reached, anihilation is strong enough to cause a reversal from contraction to expansion. This expansion is identical to the Hubble expansion. The author has thus concluded that the big bang that causes the Hubble expansion may be a 'bigger big bang' in a region on the order of 1 giga-light year.
