Zoo Hypothesis

Are we alone? Probably not. After all, astronomers have already found 4,001 confirmed exoplanets in our Milky Way galaxy, and expect there to be over 50 billion exoplanets out there. For scientists gathering in Paris today, the question is different: why haven’t we made contact with alien civilizations?

Italian physicist Enrico Fermi asked ‘where is everybody?’ back in 1950 in what’s now called theFermi Paradox. It addresses a contradiction in astronomy, and can be summarized thus: if extraterrestrial life and even intelligent alien civilizations are not just likely, but highly probable, then why have none of them been in contact with us?

FOR ALL THIS QUESTIONS THEY BROUGHT A THEORY KNOWN AS ZOO HYPOTHESIS

What is the “zoo hypothesis”?

This is a mind-warping idea that there are alien civilizations out there that know all about us but purposefully hide from us. It certainly explains the “Great Silence.”Perhaps extraterrestrials are watching humans on Earth, much like we watch animals in a zoo."

But where are aliens and how do they look like. Scientists of METI international say not like us. Where they live, they are governed by the rules of that place. Biological evolution could be random, like it is on Earth, with so many life forms. It is nearly impossible to explain how they are. and it is even more improbable to reach a final conclusion to the question – are we really alone till we are contacted or we succeed in contacting other beings.
