Scientific paper

Lemaitre and Friedman models are reanalyzed to provide an expansion constant of twice that predicted by Hubble, i.e., 100 kms/Mpc. If the greater expansion is to be accepted, astrophysical theory must be modified to find a noncosmological source of deuterium (or prove that the most of the density of the universe is not in baryons), and to account for a downward revision (by a factor of two) of the age of globular clusters. Implications of a positive cosmological constant for an expanding (accelerating) universe are discussed.
