There can be 36 interacting intelligent civilizations in our Galaxy.
According to a new study, the Milky Way may be home to at least 36 active, interacting foci of intelligent life. However, due to time and distance, we may never know if they exist or have ever existed.
Computations in this direction were based on the equation of astrophysicist Frank Drake, calculated in 1961. “Drake developed an equation that, in principle, can be used to calculate the number of interacting extraterrestrial intelligent civilizations in the Galaxy. However, many of its terms are incomprehensible, and other methods must be used to calculate the likely number of communicating civilizations, ”the authors write.
Therefore, scientists from the University of Nottingham have developed their own approach. “The key difference between our calculations and the previous ones based on the Drake equation is that we make very simple assumptions about how life evolved,” said study co-author Christopher Conselis, professor of astrophysics at the University of Nottingham.
The study is published in the Astrophysical Journal.
