Question

Quizplus · Accepted Answer

The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. It identifies the key factors that affect the likelihood of finding other civilizations such as the rate of star formation, the fraction of stars that have planets, and the fraction of those planets that are habitable. By understanding these factors, we can determine what we need to know to estimate the probability of finding other civilizations.
