Learn about the famous Drake Equation through direct manipulation of its 7 parameters with DrakeEQ. The Drake Equation states that: N = the number of civilizations in our galaxy with which communication might be possible where: 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 the above that actually go on to develop life at some point fi = the fraction of the above that actually go on to develop intelligent life fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space L = the length of time such civilizations release detectable signals into space.
