An interactive exploration of the famous equation used to estimate the number of intelligent civilizations in our galaxy, highlighting the uncertainties and fun possibilities of each variable, from the "Goldilocks Zone" to the potential for self-destructive alien species, all while pondering the implications of finding a cosmic neighbor.
N = R* × fp × ne × fl × fi × fc × L
N, the number of civilizations currently transmitting signals, depends on seven factors:
R* is the yearly formation rate of stars hospitable to planets where life could develop.
fp is the fraction of those stars with planets.
ne is the number of planets per solar system with conditions suitable for life.
fl is the fraction of...
