The Fermi Paradox asks the question of why we haven't found extraterrestrial life, considering the billions of planets in the universe. There are plenty of possible reasons, but the idea is that the rest of the intelligent species of the galaxy just don't want to be around us is as good as any. Or maybe they just haven't gotten around to exterminating us yet. This comic is from Zach Weinersmith at Saturday Morning Breakfast Cereal.
