What else is out there? JUN 26 2014
Great post on the Fermi Paradox, aka if there are so many potential intelligent civilizations out there in the universe (possibly 10 quadrillion of them), why haven't we heard from anyone?
Possibility 5) There's only one instance of higher-intelligent life -- a "superpredator" civilization (like humans are here on Earth) -- who is far more advanced than everyone else and keeps it that way by exterminating any intelligent civilization once they get past a certain level. This would suck. The way it might work is that it's an inefficient use of resources to exterminate all emerging intelligences, maybe because most die out on their own. But past a certain point, the super beings make their move -- because to them, an emerging intelligent species becomes like a virus as it starts to grow and spread. This theory suggests that whoever was the first in the galaxy to reach intelligence won, and now no one else has a chance. This would explain the lack of activity out there because it would keep the number of super-intelligent civilizations to just one.
