Are we alone? Where is everybody? DrakeEQ HD provides a visual answer to the extraterrestrial questions using the stunningly elegant Drake Equation. We've coupled the equation to a mesmerizing Milky Way in motion.

Are we alone?: DrakeEQ HD computes/displays civilization count and draws them to the display.

Where is everybody?: DrakeEQ HD approaches the Fermi Paradox by positioning the civilizations in 3D space and computing the average distances 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, N.

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

N : number of civilizations in our galaxy with which communication might be possible.
R* : yearly average rate of star formation in our galaxy
fp : fraction of those stars that have orbiting planets
ne : average number of planets (or moons) that can potentially support life per star with planets
f
: fraction of the above that actually go on to develop life
fi : fraction of the above that actually go on to develop intelligent life
fc : fraction of civilizations that are able to transmit detectable signals into space
L : length of time civilizations are able to release signals into space

This fun simulator harnesses the presentation power of the iPad to graphically quantify N. Easily perform elegant thought experiments with DrakeEQ, through direct manipulation of these seven parameters.

Enter any value or "quick pick" commonly accepted low, medium, and high guesstimates for each parameter.
