A
Expert Answer
A formula estimating the number of active, communicative extraterrestrial civilizations in the Milky Way: N = R* × fp × ne × fl × fi × fc × L. Most factors are highly uncertain, leading to estimates ranging from N=1 (just us) to millions. It's a framework for thinking about the problem, not a precise calculation.
