Researcher believes there are four malevolent extraterrestrial civilizations in our galaxy

(ORDO NEWS) — The probability that the aliens will attack us is equal to the probability of hitting a giant asteroid that can destroy life on Earth.

In 1977, the Ohio State University Big Ear telescope recorded from space a powerful burst of radio waves that lasted just 1 minute and 12 seconds.

The signal contained an alphanumeric code that was a surprise to astronomers, and it was deciphered as “WOW!”.

For decades, researchers have been trying to study the received signal and its origin, and amateur astronomer Alberto Caballero recently claimed that he had pinpointed the source of this signal .

Caballero published his findings in the International Journal of Astrobiology. However, the amateur astronomer has other jobs.

One is an article that has not been peer-reviewed but is available on the preprint server where Caballero estimates the number of dangerous extraterrestrial civilizations.

Before getting acquainted with the hypothesis, it should be noted that the work of Caballero is more of a conjecture and has not been verified by astronomers.

The purpose of the Caballero assessment is to determine the number of civilizations that could respond to our messages.

To figure this out, Caballero, who is a conflict resolution student at the University of Vigo in Spain, extrapolated some numbers from his formal field of study into an area he is more passionate about.

Caballero calculated the number of invasions that have taken place on Earth and then applied that to the estimated number of exoplanets in the Milky Way.

Italian SETI scientist Claudio Maccone previously suggested that there are 15,785 civilizations in our galaxy.

According to Caballero’s calculations, the number of civilizations that can invade us is four, and this is a hundred times less than the impact of a giant asteroid that could potentially destroy life on our planet.

Caballero’s assessment suggests that, in terms of technological advancement, these four civilizations may be similar to humans, and mathematically there is less than one civilization truly capable of the interstellar travel required for an invasion.

The researcher also suggested that as civilizations develop, they are less likely to engage in conflict. He assumes that aliens will behave in the same way as earthly humanity.

The hypothesis may turn out to be wrong, but Caballero hopes it will help us get to the important debate: should we send messages into space or not?
