#455 – Adam Frank: Alien Civilizations and the Search for Extraterrestrial Life
Adam Frank
We don't really know what nature sets for the probability of making intelligent civilizations, right? But we could set a limit using this. We could say, look, as if the probability per habitable zone planet is less than 10 to the minus 22, one in 10 billion trillion, then yeah, we're alone. If it's anywhere larger than that, then we're not the first. It's happened somewhere else.
