 | Drake equation
The Drake equation is: N=R??fp?ne?fl?fi?fc?L
where:
N = the number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);
and
R? = the average rate of star formation in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fl = the fraction of planets that could support life that actually develop life at some point
fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space |
