Can the zoo hypothesis explain UFOs?

The zoo hypothesis is the idea that we cannot see evidence of any intelligent alien life in the galaxy because it’s hiding from us. Can the zoo hypothesis explain UFOs? At first glance this question might sound ‘tin-foil hat weird’, but there is some substance to the idea. Scientists in METI (Messaging Extraterrestrial Intelligence) are discussing the zoo hypothesis and how it could affect their strategies. Let’s dig into this complex question but before we do that we need more background information.

The zoo hypothesis idea is older than you might think. The idea was suggested in 1973 by MIT radio astronomer John Ball in a paper called “Extraterrestrial Intelligence: Where is Everybody?” The paper explored different possible answers to this question and the zoo hypothesis was one of them.

The Fermi paradox

The zoo hypothesis is one possible solution to the famous Fermi paradox:

“the apparent contradiction between the lack of evidence for extraterrestrial civilizations and various high estimates for their probability “

The Fermi paradox, named after physicist and Nobel prize winner Enrico Fermi, is a mystery still to be solved. Some of its underlying arguments are relevant to the zoo hypothesis. So let’s look at those.

Consider this reasoning:

  • There are billions of stars in the Milky Way similar to the Sun.[4][5]
  • With high probability, some of these stars have Earth-like planets,[6][7] and if the Earth is typical, some may have already developed intelligent life.
  • Some of these civilizations may have developed interstellar travel, a step the Earth is investigating now.
  • Even at the slow pace of currently envisioned interstellar travel, the Milky Way galaxy could be completely traversed in a few million years.[3]
  • And since many of the stars similar to the Sun are billions of years older, this would seem to provide plenty of time.[8][9]

Given the age of the universe, 13 772 billion years, it seems like there is plenty of time for advanced civilizations to emerge.

Time is not enough, life needs somewhere to develop. Locations seem to be plentiful as Kepler space mission data tells us, there could be as much as 40 billion Earth-sized planets within our galaxy alone. These planets are orbiting in the habitable zones of Sun-like stars. This would suggest ample opportunities for advanced life to emerge and develop space-fairing technology.

“The universe is a pretty big place. If it’s just us, seems like an awful waste of space.”

Carl Sagan

Overcoming distances

The universe is really, really big. Is it possible ETs could even travel here or colonize our part of the galaxy? With our current level of technology, it would take 100 years to travel to Alpha Centauri, our closest star system at a distance of 4,37 lightyears. (This travel time is estimated in Project Longshot).

Our galaxy, the Milky Way, is estimated to be 200 000 lightyears across. My simple maths skills tell me that with current human technology it would take around 4,6 million years to cross the entire galaxy disc. While 4,6 million years is too long for my patience it’s not a long time on a cosmic scale. Presumably, this travel time can be lowered significantly by future propulsion technology.

Using self-replicating von Neumann probes (machines not that far away from our current level of technology) it’s possible to have a presence in large parts of the galaxy pretty quickly – again in cosmic time scales.

This line of reasoning suggests we should have seen evidence of advanced alien life by now… so why have we not?

Fermi paradox ‘solutions’ and the Zoo hypothesis

There are many theories as to why we haven’t seen evidence of advanced alien life. They are possible ‘solutions to the Fermin paradox’. Here are some examples.

  • Advanced life in the universe is incredibly rare. We’re the only ones in our galaxy. This is called the Rare Earth hypothesis.
  • Humans might be the first advanced civilization and we might go extinct before another civilization develops.
  • Other civilizations are not expanding or exploring.
  • They are hiding ‘at home’.
  • We’re in a simulation, the simulation does not include aliens.
  • We can’t pick up their signals, radio signals are not used.

…or they are here observing us in secrecy.

  • The zoo hypothesis. Advanced alien life hides from us intentionally and has a ‘no interference’-policy concerning Earth. The Earth and its inhabitants are being watched or monitored – much like a Zoo.

Greetings earthlings!

My name is Goran Eliasson, I live in Sweden with my wife and our two boys. In our family Gaming and Star Wars are shared interest among the boys, myself included.

I’ve always liked the Sci-Fi genre, the possibility of a fantastical future and technological progress. Another closely related interest is space and I’ve probably seen most of the space documentaries out there.

More recently I decided to write a blog about the UFO phenomena. It’s a fascinating mystery with big implications and room for a lot of speculation. But I want to separate speculation, circumstantial evidence, and real evidence (none so far :)) in the articles. I’m not a Ufologist, just a curious individual who enjoys the topic.

Hope you enjoyed, I surely Did. Awesome Read!
