Are there 4 “hostile” alien races in the galaxy containing Earth?

However, according to Live Science, the study also confirmed that the risk of Earth being destroyed by an asteroid – like the asteroid that killed dinosaurs – is still 100 times higher than the risk from hostile aliens. enemy.

Research led by astronomer Alberto Caballero from the University of Vigo – Spain has compared data on human history, the history of the formation of the Earth and the solar system, the datasets show the frequency planets that are habitable and capable of developing advanced civilizations… And even the war models of Earthlings.

From that, he calculated that the odds that modern humans would think of invading an inhabited planet – if one day we find one – is 0.028%.

Scientists have long been certain that we are not alone in the universe, when modern astronomical observations show that Earth or the solar system is not necessarily the most habitable place in the universe. However, technological limitations have not allowed humans to approach extrasolar planets, directly observe the surface of planets suspected of having life or contact aliens.

In a study previously published in the journal Mathematical SETI, Caballero calculated that a total of 15,785 civilizations are sharing the Milky Way land with humans.

But the probability of interplanetary war is low, because not everyone is aiming for war, not to mention the number of planets with a level of our level or below – that is, without the ability to travel to space. Thus the number of “hostile neighbors” is only 4.42 – the study shows.

The authors also suggest that with the development of human civilization, it will take a few hundred years for us to be able to connect with an alien race – something that astronomers around the world always wish.
