The hypothesis holds that they can see us, but we can't see them.
Earlier this month, this whole enterprise was discussed by researchers at a meeting in Paris. Douglas Vakoch, the president of METI International, a San Francisco-based organization that organized the Norwegian transmission, invoked the zoo hypothesis as a possible justification for broadcasting. After all, if the hypothesis is correct, then it’s understandable why our efforts to find signals from space have been unsuccessful.
But as Vakoch argues, this one-way scenario might be changed. If a zoo animal suddenly starts barking through the bars, saying “I’m here and I think you’re out there,” those on the other side might respond.broadcasts would tell the aliensStill, the zoo hypothesis is dependent on Earthly life being really important — our existence is apparently significant enough that it dictates the behavior of societies that might be millions or billions of years more advanced.
In addition, the idea that all extraterrestrials are keen to keep the evolution of our planet free and natural sounds odd, self-centered and a bit too altruistic. Let’s face it: The prime directive has never been in fashion with us. Indeed, we seem to prefer the opposite: On Earth, we interfere with one another’s cultural development all the time.
So the zoo hypothesis seems more than a little forced. On the other hand, I have to admit that it’s cagey.
