The Drake Equation is a formula designed to find the number of intelligent civilisations in the galaxy, using

The number of stars formed every year

Multiplied by the fraction of those stars with planets

Times the number of those planets in the solar system that could support life

Multiplied by the fraction of those planets on which life appears

Multiplied by the fraction of those life-bearing planets on which intelligence arises

Times the fraction of those that would become technologically advanced with a desire to communicate

Multiplied by the length of time that they continue to transmit detectable signals into space

What is the Equation and do you think this is true?

N = R*fp ne fl fi fc L Where: N= the number of communicative civillizations
R*= The rate of formation of suitable stars
fp= The fraction of those stars with planets
ne= The number of Earth-like worlds per planetary system
fl= The fraction of those Earth like planets where life develops
fi= The fraction of life sites where intelligence develops
fc= The fraction of communicative planets
L= the "lifetime" of communicating civilizations
