In this paper we propose a mechanism for the formation of galaxies which depends on a characteristic feature of the steady state universe, namely, that any particular galaxy is formed in a universe already full of galaxies. The gravitational fields of these pre-existing galaxies produce density concentrations in the intergalactic gas so that new galaxies can form as a result of gravitational instability. The condition that the properties of this system of galaxies be independent of time suffices to determine these properties uniquely, i.e. without any adjustable parameters. This theoretical distribution is in reasonable agreement with observation for the average mass, size, separation, peculiar velocity and clustering tendencies of galaxies. These results suggest that the steady state theory may enable one to account for the actual distribution of matter in the universe entirely in terms of the general laws and constants of nature.
