The question of whether people are alone or not in the universe has long fired our fantasies, including the world's top minds. The lack of extraterrestrial evidence and probably a high probability that they exist has continued to confuse experts.
METI (Messaging Extraterrestrial Intelligence) researchers have suggested that foreigners could hold people in a "galactic zoo", simply looking at us without revealing themselves, because they would have been to us. avoids triggering pandemonium on earth.
Scientists from all disciplines gathered in a Parisian science museum to explore a 1950's condominium known as the Fermi paradox.
Although it is a worrying thought, a growing scientific consensus believes foreigners Jean-Pierre Rospars, an honorary research director at the Institut National de la Recherche Agronomique, said: "It seems likely that aliens are putting in a galactic quarantine because they realize it would be culturally disturbing for us to learn about them.

"There is no reason to believe that humans have reached the highest cognitive level.
"Higher levels can be developed on earth in the future and already reached elsewhere."
And the researchers say that humanity must be more direct in its approach to contact.
Dr Douglas Vakoch, president of METI, draws the analogy with an animal animal that suddenly knocks out prime numbers with its hoof.

Such an unexpected and extreme act would surely trigger an answer from the observer.
Dr Vakoch said: "Perhaps extraterrestrial looking at people on earth as we look at animals in a zoo.
" How can we get the galactic zoos to reveal themselves? "
And this prompt can be radio signal transmissions to nearby stars.
This has been trying on several occasions over the past few decades, when scientists radiated – for the first time – a deliberate message in space, using the Arecibo radio telescope in Puerto Rico.

What is the Fermi paradox?
Italian physicist Enrico Fermi asked "where is everyone?" Back in 1950 in what is now called the Fermi paradox.
The Fermi paradox addresses a contradiction in astronomy, summed up as: if extraterrestrial life and even intelligent alien civilizations are not only probable but very likely, why has no one contacted us?
Are there biological or sociological explanations for this "Great Silence"?
