According to one of the researchers, there are four extraterrestrial civilizations in the Milky Way that could attack planet Earth. Doctoral student at the University of Vigo in Spain Alberto Caballero came to the conclusion that there may be hostile civilizations in our surroundings, that is, those that tend to attack the Earth.
Research is more than a “thought experiment”. The article, entitled Estimating the Proliferation of Malignant Civilizations Extraterrestrial, aims to warn other scientists and put a number on the civilizations that could eventually return to the messages being sent.
The estimate is based on the world history of invasions in the last century, the military capabilities of the countries involved and the global growth rate of energy consumption. Alberto used as a basis the time frame from 1915 to 2022, anticipating what would be the probability of Earth’s invasion of another planet.
The study was conducted on the basis of statistical probability. Alberto applied the number of invasions to Earth, including the WoW signal, to the estimated number of exoplanets in the Milky Way. According to calculations, the number of civilizations that can conquer our planet is four.
Alberto also warned scientists to be careful when using extraterrestrial intelligence (METI) technology for fear that it could lead to an invasion.
Caballero explains that he conducted the research based solely on human life and adds that because he doesn’t know the minds of aliens, the pathological responses sought may not be the same.
However, the study concluded that the probability of the Earth suffering from an extraterrestrial invasion is less than the possibility of the extinction of the human race through a collision with an asteroid.
