Scientists are sure that there are more than 30 a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ on distant planets with which one could establish contact.
A group of researchers from the University of Nottingham (UK) conducted a corresponding study and concluded that 36 e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ can be contacted in our galaxy. The results of the study were published in The Astrophysical Journal
The team of scientists, led by professor of astrophysics Christopher Conselice, came to this conclusion, believing that intelligent life is formed on other planets in much the same way as on Earth.
“Our research shows that the search for e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ not only reveals an understanding of how life is formed, but also gives us clues about how long our civilization will last,” said Conselice.
Professor Conselice continues: “Our new research suggests that searches for e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ not only reveals the existence of how life forms, but also gives us clues for how long our own civilization will last.
“If we find that intelligent life is common then this would reveal that our civilization could exist for much longer than a few hundred years, alternatively if we find that there are no active c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ in our Galaxy it is a bad sign for our own long-term existence. By searching for e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ intelligent life — even if we find nothing — we are discovering our own future and fate.”
In their work, astrophysicists proceeded from the “Copernican principle”, based on a philosophical concept used in astronomy, which assumes that the Earth is not the only planet in the Universe on which there can be life.
In addition, scientists were based on the Drake equation, which takes into account seven factors necessary for the development of intelligent life on another planet, taking into account the star and the planet orbiting around it with favorable conditions for life.
Using mathematical modeling, scientists have determined that there may be about 36 technically advanced c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ in the Milky Way.
The researchers also took into account in their work that it will take at least 5 billion years to form intelligent life on other planets, that is, almost the same as on Earth.
Therefore, astrophysicists are sure that in our galaxy there should be at least several dozen active intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳.
