Intelligent alien life - could it be the zoo hypothesis or nothing ?

A new study has highlighted the increasing likelihood that the reality of intelligent alien life can be boiled down to two possibilities.
The question of whether we are alone in the universe remains one of the biggest philosophical conundrums of our time. While it seems almost inconceivable that our civilization is alone in the cosmos, the fact still remains that we have yet to see any evidence to the contrary.
The Fermi paradox, which highlights the contradiction between the likely existence of extraterrestrial civilizations and the fact that we have still never encountered any, seems to suggest that either there are no aliens out there, or they are so rare that it is unlikely we would ever come across them.
Now according to a new study, the fact that we have yet to discover any conclusive evidence of intelligent alien civilizations suggests that the Fermi paradox may have only two possible answers - the zoo hypothesis or nothing.
The zoo hypothesis is essentially the idea that intelligent alien civilizations are aware of our existence but prefer to keep their distance to allow us to develop on our own. This scenario is similar to the 'prime directive' in
Star Trek which forbids the Federation from interfering with pre-warp civilizations.
The alternative, researchers argue, is 'nothing' - or more specifically, the likelihood that intelligent alien life is either non-existent or so extremely rare that we are never likely to encounter it.
The more extrasolar planets we discover and the more we learn about the universe without finding evidence of intelligent aliens, the more likely it is that the answer to the Fermi paradox is one of these two possibilities.
What's more, even the zoo hypothesis will become less likely the further we explore space.
"The longer we do not detect any signs of advanced intelligent life around us, the less likely the zoo hypothesis becomes as an explanation, forcing us to conclude that technological intelligent life is rare in the universe," the researchers wrote.
"It is in this sense that we propose that the solution to the Fermi paradox is the zoo hypothesis or nothing."
The study authors even go so far as to suggest that we may know which of these two options is the answer within as little as 50 years.
