Abstract
Baryon inhomogeneities in the early high-density universe may account for the origin of galaxies. Any such inhomogeneity is amplified by baryon-pair annihilation as the universe expands and can eventually result in the formation of galaxies and antigalaxies. This process is more efficient than the usual process which assumes that the initial conditions of a structured universe are density fluctuations.Keywords
