While numerous theories and principles attend to the Fermi paradox, the most closely related is the [[Drake equation]]. | While numerous theories and principles attend to the Fermi paradox, the most closely related is the [[:en:Drake equation]]. | ||
The equation was formulated by Dr. [[Frank Drake]] in 1960, a decade after the objections raised by [[Enrico Fermi]], in an attempt to find a systematic means to evaluate the numerous probabilities involved in alien life. The speculative equation factors: the rate of [[star formation]] in the galaxy; the number of stars with planets and the number that are habitable; the number of those planets which develop life and subsequently intelligent communicating life; and finally the expected lifetimes of such civilizations. The fundamental problem is that the last four terms (fraction of planets with life, odds life becomes intelligent, odds intelligent life becomes communicative, and lifetime of communicating civilizations) are completely unknown. We have only one example, rendering statistical estimates impossible, and even the example we have is subject to a strong [[anthropic bias]]. | The equation was formulated by Dr. [[Frank Drake]] in 1960, a decade after the objections raised by [[Enrico Fermi]], in an attempt to find a systematic means to evaluate the numerous probabilities involved in alien life.
