Kepler 186f is special because it marks the first planet almost exactly the same size as Earth orbiting in the habitable zone the distance from a star in which we might expect liquid water, and perhaps life. What did not make the news, however, is that this discovery also slightly increases how much credence we give to the possibility of near-term human extinction. This because of a concept known as the Great Filter. The Great Filter is an argument that attempts to resolve the Fermi Paradox: why have we not found aliens, despite the existence of hundreds of billions of solar systems in our galactic neighborhood in which life might evolve? As the namesake physicist Enrico Fermi noted, it se...
