Summary
Weinberg returns to the “The Cosmological Constant Problem” and suggests an anthropic principle solution. Anthropic reasoning could make it possible for us to calculate the effective vacuum energy. Observations of dark energy in 1998 show that the expansion of the universe is accelerating. This observational result is not inconsistent with the notion of a possible multiverse – the issue has not been settled.
