Why can’t we see evidence of alien life?
Chris Anderson explores the question of Fermi’s Paradox for TED-Ed. Some of the answers are frightening, and some are hopeful. Perhaps intelligent life, in quest to increase efficiency, tends toward smaller scales that are, ultimately, much harder for us to detect?
Goes hand-in-hand with my episode "The Odds of Finding Life and Love", which has a Carl Sagan cameo in it and explores the most modern exoplanet stats.
After you’ve aimed your mental radio telescopes at both of those, check out this SETI/TED collab video from Jill Tarter and learn more about how the odds of intelligent life are calculated.
