The 'Zoo Theory' adds a twist to alien conspiracies

December was a crazy month for extraterrestrial life, from a New York Times article exposing secret alien research programs to Elon Musk’s SpaceX missile launch over Los Angeles that sent the city into alien-hysteria for a few hours. From a scientific perspective, it seems unreasonable to think that we’re alone in this universe, or even this galaxy. But if there are aliens, why haven’t we met them yet? The answer may be complicated.
One popular theory to explain why aliens have not made open contact with humans is the “Zoo Theory.” John A. Ball, a MIT radio astronomer proposed the theory in 1973, suggesting that aliens may purposely be avoiding contact with humans as to not interfere with our activity, similar to zookeepers at a zoo or nature preserve, Science Alert  reported.
“ETI (extraterrestrial intelligence) may be discreetly and inconspicuously watching us but not dabbling, “ Ball wrote in his paper on the subject.
