If the Pentagon Is Hiding Aliens from Us, the Zoo Hypothesis May Explain Why

Recent revelations that the Pentagon had an actual alien-hunting division have rocked conspiracy theorists everywhere, adding fuel to the long-held beliefs of many that the government is hiding the truth from us. Luis Elizondo, the military intel official who headed the now-defunct “Advanced Aviation Threat Identification Program,” which ran from 2009 until 2012, was so convinced by what he saw that he continued his search for E.T. until this day. He now has a UFO-research startup and alerted CNN that there’s “compelling evidence” we are not alone.

While Elizondo’s evidence may be based on being privy to a number of unexplained encounters with flying objects, the aliens haven’t made their presence very clear. If the universe contains at least two trillion galaxies full of billions of stars like our sun, shouldn’t there be other complex life forms out there by now? It would only make sense. So “where is everybody?” as the Nobel laureate physicist Enrico Fermi famously asked about the absence of evidence and the high probability of alien existence.

There are certainly many speculations about the possibility of aliens and their potential motives. It could be that there’s been no contact because they are too far away, and we need for our technologies to catch up before we meet up. They could look like something else entirely so we can’t even perceive them yet. Or maybe we underestimate the uniqueness and preciousness of humanity and we really are alone. But an idea formulated in the 70s takes a different swing at this compelling issue.


The Zoo Hypothesis, proposed by the MIT radio astronomer John A. Ball in 1973, says that aliens may be avoiding contact with us on purpose, so as not to interfere with our evolution and the development of our societies. The human civilization could be essentially living in a “zoo” or a space wildlife sanctuary, where others populating the cosmos dare not go. By staying clear of us, they avoid interplanetary contamination.

Perhaps the aliens are waiting for us to reach a certain technological or moral point before they will talk to us. Or they may be simply trying to protect us and themselves. You’ve seen “Independence Day” - there may be a similar movie made thousands of light years away about us.

This idea of the zoo hypothesis presumes that aliens would want to have some relatively benevolent system of belief - perhaps a universally-accepted law about how to treat lower-level cosmic inhabitants. One explanation could be that a higher intelligence would not want to limit the diversity of paths in the universe by somehow interfering with other beings.

The hypothesis makes the most sense in a crowded universe, if there are many civilizations which set up rules by which they govern their coexistence. Of course, if there are many extraterrestrial players, it is also doubtful that one of them wouldn’t have somehow contacted us, even if by accident. Maybe that’s what the Earth’s alien hunters are picking up on - random, unsanctioned interactions.

Of course, if we put our tinfoil hats on, it also stands to reason that if there is some kind of Universe-wide law of non-interference with other species, someone at the Pentagon could be in on it.
