Milky Way galaxy has 4 ‘malicious’ alien civilizations that might attack Earth: researcher


There could also be 4 extraterrestrial civilizations within the Milky Way that might attack our planet, a researcher has claimed.

Alberto Caballero, a PhD student on the University of Vigo in Spain, authored a study within the International Journal of Astrobiology earlier this month by which he claimed that he pinpointed the so-called “WoW! Signal.”

The signal, which was first detected by a radio telescope in 1977, was an odd minute-long burst of radio energy that will have originated from a Sun-like star 1,800 lightyears from the Earth, based on Caballero.

It was first received by the Big Ear telescope at Ohio State University and is taken into account the very best candidate signal of extraterrestrial life since humans began searching greater than 60 years ago, Vice News reported.

Caballero’s paper, which is titled “Estimating the Prevalence of Malicious Extraterrestrial Civilizations,” has “some limitations,” the creator admitted.

Caballero’s research has not been peer-reviewed by other astronomers, and the paper is taken into account to be more of a “thought experiment.”

He warned scientists to make use of caution in using the practice of METI, or “Messaging Extraterrestrial Intelligence” for fear it could provoke an alien invasion.

But Caballero conceded that the percentages of extraterrestrials wiping out the human species is concerning the same because the planet being destroyed by a “global catastrophe asteroid.”

He wrote that such an event takes place once every 100 million years, so humans are in all likelihood protected in the interim.

In putting together the study, Caballero researched human “invasions” of other countries over the past 50 years.

He then used that data and applied it to the variety of known “exoplanets” in our galaxy, which Italian scientist Claudio Maccone estimated to be around 15,785.

Using the frequency of human conflict — which has decreased within the last half century as technology has advanced — and applying the maths to outer space, Caballero estimates that there might be 4 “malicious” alien civilizations.

“I did the paper based only on life as we understand it,” Caballero told Vice.

“We don’t know the mind of extraterrestrials. An extraterrestrial civilization can have a brain with a distinct chemical composition and they may not have our empathy or they may need more psychopathological behaviors,” he said.

“I discovered this method to do [the study], which has limitations, because we don’t know the mind of what aliens can be like.”

The US government has in recent months taken seriously increasing signs of extraterrestrial life, though there remains to be no definitive proof.

An interim report released by intelligence officials last 12 months counted 144 sightings of aircraft or other devices apparently flying at mysterious speeds or trajectories.

In all but one in every of the sightings investigated, there was too little information for investigators to even broadly characterize the character of the incident.
