According tomedia reports, humans have long fancied that other intelligent life may live in our vast universe, possibly on a habitable planet similar to Earth. With hundreds of billions of stars in the Milky Way and an estimated billions of potentially habitable exoplanets, it’s hard to guess how many extraterrestrial intelligent civilizations we might have nearby. And according to a new study, that number could be very small.
Several studies over the years have tried to estimate how many extraterrestrial intelligence civilizations may exist in the Milky Way, but this has proved to be not a useful thing — estimates range from no amount to billions, and this cannot be completely narrowed. The new study, from the University of Nottingham, provides a more accurate figure.
Of course, it’s not clear how many extraterrestrial intelligent civilizations might be in the Milky Way, but researchers say that number could be around 36 — a tiny fraction of the number of potentially habitable exoplanets in the Milky Way. This figure refers specifically to intelligent civilization with advanced technology, refers to a civilization like the Earth, developed to a certain extent, can use satellites and other things to send signals to space. Despite this progress, it may be difficult or impossible for humans and these aliens to detect each other because of the huge distance between each planet.
Professor Christopher Conselice explains.
Our new research shows that the search for extraterrestrial intelligent civilization sings not only the way life forms exist, but also gives us clues as to how long our own civilization can last. If we find that intelligent life is common, it will reveal that our civilization may have existed for much longer than a few hundred years, or if we find that there is no active civilization in the Milky Way, which is a bad sign for our own long-term existence. By searching for extraterrestrial intelligent life — even if we get nothing — we are discovering our future and destiny.
