Abstract

The better understanding of the synthesis of heavy elements by the r-process-based on an improved description of nuclear beta decay far from stability -, and the investigation of globular clusters led to a larger age of the universe of ≥ 15 × 109 a. It will be shown that with the assumption of inflationary expansion at the beginning of the evolution of the universe such a number leads to a nonvanishing cosmological constant A in the Friedmann equation for a Hubble constant H0 ≥ 45 Mpc-1 sec-1. Consequences of a nonvanishing A (corresponding to a nonvanishing energy density of the vacuum) are more stringent limits on the amount of dark matter in the universe and on the neutrino mass.
