摘要：

We review the cosmological evidence for a low matter density universe and a cosmological constant or dynamical vacuum energy and address the cosmological coincidence problem: why is the matter density about one-half the vacuum energy now. This is reasonble, following the anthropic argument of Efstathiou and of Martel, Schapiro & Weinberg.
