British astrophysicists have calculated that there are at least 30 intelligent civilizations in our galaxy.
When, almost 500 years ago, Nicolaus Copernicus, and then Giordano Bruno, questioned our place in the universe by suggesting the existence of other worlds, the wrath of the holy Inquisition descended on them. The very idea of that.
it does not revolve around the Earth, and there are other planets in the vastness of the Universe in those years it was considered a crime, but today robotic vehicles plow the space expanses, and people constantly live in the orbit of our planet (we are talking about the ISS). But despite the discovery of more than 4,000 exoplanets, we have not been able to find traces of alien life. But does that mean we’re alone? According to the results of a study by scientists from the University of Nottingham, there may be more than 30 intelligent civilizations in our Galaxy.
Life beyond the Earth.
When I think of life beyond Earth, I am reminded of the words of the brilliant science fiction writer, Sir Charles Arthur C. Clarke: “There are two possibilities: either we are alone in the universe, or we are not. Both are equally terrible.” But even despite the “horror” that hides the answer, the search for extraterrestrial life forms continues. Humanity has learned that the Universe is not limited to the Solar system. Images of 200 thousand galaxies taken by the Hubble space telescope cause dizziness, and questions about the nature of things are becoming more and more.
The scientific method allowed a person to go into outer space, send real robots to the nearest planets, and even send one of them straight to the Sun. Undoubtedly, science is the only way to know the structure of the world and the universe. Recently, British scientists have discovered that there may be more than 30 alien civilizations in our galaxy. The new work was aimed at understanding how many planets in our area could be home to alien life. I note that the researchers assumed that life develops on other planets in the same way as on Earth.

As the astronomers write in a paper published in the journal.
in the Milky Way, there may be dozens of active civilizations waiting in the wings. Moreover, the work can also shed light on our own fate and suggests that our prospects for long-term survival are lower than we might think.
There must be at least a few dozen active civilizations in our Galaxy, assuming that it takes 5 billion years for intelligent life to form on other planets like Earth. The idea is to consider evolution on the scale of the cosmos. We call this calculation the Astrobiological Copernican Principle.
Christopher Conselis, Professor of astronomy at the University of Nottingham.
The Copernican principle (also the principle of mediocrity and mediocrity) is that neither the Earth nor the Sun occupy any special position in the universe.
As the researchers write in the paper, the astrobiological principle of Copernicus is of two types. One of them is the “weak” principle, which assumes that intelligent life forms on the planet at any time after 5 billion years. Another “strong” principle suggests that life on the planets formed between 4.5 and 5 billion years ago.
More than 30 advanced civilizations can easily exist in the Milky Way.
In the work, the scientists proceeded from the” strong ” Copernicus principle and suggested that alien life forms should develop in metal-rich environments. This is because humans evolved near a metal-rich environment due to the metal present in the Sun. How.
The Independent, previous research conducted in 2012 suggests an acceptable “minimum amount of stellar metals” needed to form Earth-like planets. The researchers then used assumptions about where life might form to understand how many planets in the Milky Way would be able to meet these conditions.
I note that the detection of any civilizations in our galaxy is highly dependent on our ability to pick up signals sent into space. These include satellite radio broadcasts and television. If advanced technological civilizations survive as long as ours (and we’ve been sending signals into space for the last century or so) then, according to scientists, there may be 36 intelligent civilizations in our Galaxy!

So, if the authors of the new study are right, then why have we not yet received any evidence of the existence of other intelligent life forms? The authors of the work believe that it’s all about cosmic distances – the average distance to any possible existing civilization is 17,000 light-years, which makes communication a very difficult task. As for other reasons, the answer is, alas, disappointing: we are the only intelligent life in the galaxy, and civilizations die out before they can be discovered.
We all want to believe that we are not alone in this frightening, cosmic void.
Do you really think there are 36 intelligent civilizations in the Milky Way? Share your answer in the comments section of this article, as well as with the participants.
If ever scientists discover that intelligent life is widespread in the universe-I recently wrote about it.
– then it will show that our civilization can exist much longer than a few hundred years.” And if the traces of intelligent civilizations can not be found, it will mean that the long-term existence of our civilization is not possible.
Anyway, in the search for extraterrestrial intelligent life – even if we find nothing — we study our own future and destiny.
