Abstract.
Contradictions between cosmological theory and observations are
greatly eased if luminous galaxies are not reliable tracers of the
distribution of mass. However, an analysis of existing data suggests
that light and mass do have the same distribution on scales larger
than about one hundred kiloparsecs. This implies that the cosmic
density parameter,
0.15, and that baryons probably
dominate the mass of the universe.
