Scientific paper

Observations of galaxy clustering indicate that the mean mass density is only about one-third of that predicted by the popular Einstein - de Sitter cosmological model. Theory and observation can be reconciled if there has been large-scale segregation of galaxies from mass, but the gravitational instability of the expanding universe would tend to destroy such a segregation. Thus either conventional ideas about galaxy formation are wrong, or the Einstein - de Sitter model is not a useful approximation.
