There could be 36 extraterrestrial races in our galaxy, says study

To date, no one has found credible (publicly known) evidence that alien civilizations exist. What if there were 36 extraterrestrial races in our galaxy alone?

However, a new study reveals that there could be over 30 alien civilizations in our galaxy alone.

A conclusion reached by a group of researchers after searching our closest galactic neighborhood in search of planets that could harbor life forms similar to those that develop on Earth and that could harbor similar evolution.

According to a study published in the scientific journal ‘ The Astrophysical Journal ‘, only in the Milky Way there would be more than three dozen possible active alien civilizations.

Christopher Conselice, a professor at the University of Nottingham and one of the research directors, explains to the Independent that “there must be at least a few dozen active civilizations in our galaxy, assuming it takes five billion years for life to form on other planets. , like on Earth. Earth.

Conselice points out that “the idea is to look at evolution, but on a cosmic scale.
We call this calculation the Copernican Astrobiological Limit.”

That limit would appear in two ways: a “soft” limit, where intelligent life forms on a planet any time after five billion years, and a “hard” limit, which I would bet on because life formed between 4.5 billion and 5 billion years ago.

This was the scenario on which the research was based, which was also supported by the fact that these new species would need metal-rich environments to develop, as humans evolved in the metal-rich solar environment.

A bad sign for Earth if there are no alien civilizations in our galaxy.

The Drake equation is a way of arriving at an estimate of the number of space-traveling, technologically
advanced civilizations in the galaxy or Universe today.
But until we know how to estimate these parameters, we’re just guessing at possible answers.

Scientists believe that in order to detect any kind of civilization in our galaxy, you need to be able to collect the signals that are sent out into space.

Given that Earth has been sending radio signals through satellites or television for nearly a century,
it can be concluded that there could be as many as 36 intelligent civilizations currently in this galaxy.

However, even if this hypothesis were true, communication would be very complicated, as the average distance for any of these civilizations would be around 17,000 light years, which would complicate any form of communication.

If we discover that there are no active civilizations in our galaxy, it is a bad sign for our very existence.
But the researchers value another possible scenario, according to which humans on Earth are the only intelligent life in the galaxy and that civilizations are extinct before we can detect them.

In this case, according to Professor Conselice, “the search for intelligent extraterrestrial civilizations not only reveals the existence of how life forms, but also gives us clues about how long our own civilization will last”.

Therefore, he points out that the long-term prospects for human survival would be less than one might assume: “If we found that intelligent life is common, it would reveal that our civilization could be an alien civilization that came to Earth from another planet. .

But if we discover that there are no active civilizations in our galaxy, it is a bad sign for our very existence.

By looking for extraterrestrial intelligent life, even if we don’t find anything, we are discovering our own future and destiny.
