Are we alone? Where is everybody? DrakeEQ HD (v6.0.1) invites you to partake in a highly visual thought experiment using the stunningly elegant Drake Equation to help answer those very enigmatic questions.

With the equation coupled to a mesmerizing Milky Way in motion, DrakeEQ HD computes civilization count and positions these civilizations in 3D space — computing the average distances between them.

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

N = R* X fp X ne X f X fi X fc X L

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 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 above that actually proceed to develop life
fi: fraction of above that actually proceed to develop intelligent life
fc: fraction of civilizations that are able to transmit signals into space
L: length of time in years that civilizations are able to transmit signals into space
