Are we alone?
We created DrakeEQ to provide a visually elegant answer to the extraterrestrial question, using the intellectually elegant Drake Equation. We coupled this fun calculator with beautiful, 3D galaxies in motion!
To help us celebrate 15 years since the first release in 2009, DrakeEQ 7.0.0 now features our Galaxene Galaxy Engine!
Use this fun simulator to graphically quantify the number of advanced extraterrestrial civilizations in our Milky Way Galaxy.
Travel the Universe and explore infinitely variable galaxies! Just pinch anywhere and tap the targeting indicator.
Perform thought experiments with this unique visual tool; it’s both educational and entertaining.
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.
