Recent developments in inflationary and quantum cosmology furnish reasons for favoring an essentially 'flat' universe whose Omega value is 1. Cosmologists favorable to these concepts must postulate that the bulk of the matter in the universe is nonbaryonic, or else adopt a nonstandard model for the nucleosynthesis of the light elements. The 5-10 times more mass (that is required for the Omega = 1 value) than can be inferred from virial-type considerations can only be reconciled with dynamical arguments if the galaxy distribution gives an exaggerated impression of overall inhomogeneity on scales of 10-20 Mpc.
