Why hasn’t Earth received any messages from extraterrestrials yet? Perhaps because we’re already unwitting inhabitants in a so-called galactic zoo.
This was one of the scenarios a group of international researchers explored on March 18 at a meeting organized by the nonprofit organization Messaging Extraterrestrial Intelligence (METI). The gathering, which took place at the City of Science and Industry museum in Paris (Cité), brought together about 60 scientists who research the possibility of communication with hypothetical intelligent extraterrestrials.
There, they debated “The Great Silence” — why aliens haven’t contacted us — exploring one possibility known as the “zoo hypothesis.” First proposed in the 1970s, it describes Earth as a planet that is already under observation by “galactic zookeepers” who are deliberately concealing themselves from human detection, Forbes reported.
