A New Cosmological Paradigm: the Cosmological Constant and Dark Matter

Abstract

The Standard Cosmological Model of the 1980's is no more. I describe the definitive evidence that the density of matter is insufficient to result in a flat universe, as well as the mounting evidence that the cosmological constant is not zero. I finally discuss the implications of these results for particle physics and direct searches for non-baryonic dark matter, and demonstrate that the new news is good news.Comment: 11 pages, latex, including 4 embedded figs.
