As per a researcher, about four malicious extraterrestrial civilizations in the Milky Way can attack our planet.
According to Vice, Alberto Caballero, a Ph.D. student at the University of Vigo in Spain, the exact source pinpointed the “WoW Signal,” which was identified in 1977 and was a strange minute-long burst of radio energy.
He further explained that the Big Ear Telescope located at Ohio State University received a burst of radio waves lasting about 12 seconds. The signal consisted of an alphanumeric code dubbed “WoW Signal.” It has been the best candidate for extraterrestrial life since humans started searching more than 60 years ago.
For more than decades, scientists and researchers have attempted to analyze the signal and its origins more detailedly. Finally, in his paper “Estimating the Prevalence of Malicious Extraterrestrial Civilizations,” Mr. Caballero asserted that he pinpointed the exact source of this signal. As per him, it has its genesis from a Sun-like star 1,800 lightyears far from the Earth.
Research conducted by Mr. Caballero is deemed to be more of a “thought experiment.” The researcher said that the motive of his paper was to warn other scientists and put a number to the civilizations that could possibly reply to the messages we send out. He also cautioned scientists to be alert in using the practice of Messaging Extraterrestrial Intelligence (METI), for it could agitate and incite an alien invasion.
However, the researcher also highlighted that the chances of extraterrestrials attacking and eliminating the human species is about the same as the Earth being hit by a “planet-killer asteroid.” Mr. Caballero wrote in his paper that such an event takes place once every 100 million years, so humans are in all likelihood safe for the time being.
The researcher remarks that as societies develop, they are less likely to be involved in the conflict, indicating that an alien force can also follow the same behavior as they develop technologically.
