Researcher says there are only ‘4 alien civilizations’ hostile in our galaxy, or around us (photos)

Researcher Stephen Hawking had once warned that the transmission of signals from earth to space could lead to the extinction of human civilization.

“If aliens visit us, the result would be more or less like when Christopher Columbus first landed in America and exterminated all Native American-Indian cultures.”

Hawking’s comments seem to have been taken into account, but how many civilizations “evil” extraterrestrial can there be? And what are the possibilities for them to decide to act towards people?

Not many studies have been done on this but some researchers have put forward interesting hypotheses.

In an American document that can read here the author acknowledges that despite the lack of information, our Milky Way galaxy is home to about four malicious alien civilizations.

A document written by Alberto Caballero of the University of Vigo in Spain says the chances of a malevolent alien civilization taking control of the land are “low”.

Caballero further writes that the chances of being invaded by an alien civilization are about twice as low as those of being struck by a giant asteroid, although the chances of the latter occurring are one in a few tens of millions of years.

He adds that not many civilizations have achieved interstellar flight technology. But in such a case he says that this makes them the so-called “Type 1” civilization that are considered more advanced and therefore more dangerous.

According to Caballero, there have been fewer and fewer alien invasions as technology has evolved, perhaps because alien civilizations that can destroy the earth are less interested in doing so as they improve their technology.

“I wrote the document based on life as we know it. “We do not know the mind of aliens, their brains may be composed of other chemicals and may not have our psycho-pathological behavior,” he told the network. MotherBoard.
