Title: MATTER-ANTIMATTER ANNIHILATION AND COSMOLOGY

Abstract

The general symmetry between matter and antimatter, which has been confirmed through the discovery of the negative proton, requires that the universe should contaln equal quantities of both. A theory of the development of the metagalactic system is discussed. The system---which is not identlfied with the whole universe---is thought to have originated as a sphere of very dilute plasma containing equal quantities of matter and antimatter. The sphere contracted due to gravitation but when the density reached a critical value ( approximates 10/sup -2/ atoms cm/sup -3/) the annihilation became important. Thereby the inward motion was stopped and converted into the present outward motion connected with the redshift of the galaxies. An electromagnetic process is considered by which the matter-antimatter plasma was electrolyzed so that clouds of separated matter and antimatter were produced. It is pointed out that a cloud of matter repels a cloud of antimatter due to a Leidenfrost phenomenon. The theory leads to the conclusion that even today there must be equal quantities of matter and antimatter in our metagalaxy. The question is raised whether our own galaxy may contain antimatter.
