In recent studies conducted by scientists searching for e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳, they found evidence that in just a few decades we can find life outside of our planet.
At the moment, the chances of finding life in space have increased significantly, because the equipment, spaceships and other things that are required to effectively conduct a mission to study stars and planets have been improved.
It is practically impossible to calculate exactly how many potential e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ can actually exist.
But scientists from the University of Nottingham approached this issue from a completely different perspective. Researchers are confident that in our galaxy in fact there can be more than thirty c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳.
“There should be more than 30 c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ in our galaxy, given that for the development of intelligent life on other planets, like ours, it takes about 5 billion years,” said Christopher Conselis, the author of the latest study.
The idea of this study is to consider evolution not on such a huge scale as before. A similar calculation was called the Astrobiological Limit of Copernicus.
This calculation suggests that, on average, it takes 5 billion years to form intelligent life. In the case of our planet, c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ has been fully formed already in 4.5 billion years.
Experts added that if there is intelligent life on other planets that exists about the same time as on our planet, then in total there can be 36 c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ in the galaxy. Scientists plan to continue research in this direction to obtain more accurate evidence of this theory.
