Drake’s Equation can be used to (gu)estimate the number of intelligent, technologically capable civilizations that are out there, somewhere, in the Galaxy today. However, it is not so much a precision equation as it is an attempt to break a large, nearly-impossible-to-answer question into a handful of smaller, easier-to-manage — but still nearly-impossible-to-answer — questions. Despite this, we will throw caution to the wind, discuss the known knowns and the known unknowns of each of these questions — and then vote. Everyone will get one vote per question, and will submit it using a custom web interface that we made just for this talk. We will see what the group comes up with, multiply it by the number of galaxies in the (known) universe, and be amazed by the result!
