Let's Talk About Extraterrestrial Life: The Drake Equation

The Drake equation attempts to estimate how many civilizations might exist in our own galaxy--are we the only one? Or are there millions out there waiting to be discovered? Let's discuss it! N: number of civilizations in the galaxy with detectable emissions R∗: stellar formation rate fp: fraction of stars that host planetary systems ne: number of planets, per planetary system, that are habitable for life (fp*ne= η⊕) fl: fraction of habitable planets that actually develop life fi: fraction of life-bearing planets that have intelligent life emerge fc: fraction of those intelligent civilizations that actually create detectable emissions L: lifetime or average length of time such civilizations are emitting Find me: http://galaxy.nora-bailey.com/linktree/ #extraterrestriallife #drakeequation #aliens
