Are we alone? Where is everybody?
More than simply a Drake Equation calculator, DrakeEQ (v6.0.2) is a 3D simulator that answers the extraterrestrial question. Use this fun simulator to graphically quantify the number of advanced extraterrestrial civilizations in our Milky Way Galaxy. DrakeEQ is both educational and entertaining. Easily tweak equation variables using fun, drop-down manipulators.

Are we alone?: DrakeEQ computes the civilization count and draws them to the display. It positions the civilizations in 3D space and computes the average distance between them.

The Drake Equation primarily allows scientists to quantify the uncertainty of the factors which determine the number of “intelligent” extraterrestrial civilizations contained in our galaxy.


The Drake Equation states that:
N = R* x fp x ne x fℓ x fi x fc x L

N
Number of civilizations in our galaxy with which communication is possible
R*

Yearly average rate of star formation
fp

Fraction of those stars that have orbiting planets
ne

Average number of planets (or moons) that can support life per star with planets
fl

Fraction of those (planets/moons) that actually proceed to develop life
fi

Fraction of those (planets/moons) that actually proceed to develop intelligent life
fc

Fraction that are able to transmit signals into space
L

Length (years) that civilizations are able to transmit signals into space
