Steigman, G

In approaching the problem of the amount and astrophysical role of antimatter in the Universe, it is valuable to distinguish between two separate questions. First, must the universe be symmetric. Does an application of the microscopic laws of physics to the macroscopic scale of the Universe require that there be exactly equal numbers of particles and antiparticles. In contrast, is the Universe symmetric. The extent to which these questions can be or have been answered is the subject of this review. 2 tables, 118 refs. (GHT)
