Research claims – 4 civilizations of aliens are present in our galaxy, can attack the earth

Aliens have always been a topic of debate for our world. Scientists neither deny their existence nor confirm their existence with certainty. Our galaxy, also known as the Milky Way, is estimated to have millions of planets that could be habitable. Now a new research shows that about four such planets can give shelter to evil alien civilizations. These aliens can attack the earth. This research has been posted in the preprint database arXiv. Although this research paper has not yet been reviewed, it raises the question of what are the possibilities that humans may one day contact enemy aliens who have the power to attack our planet.

livescience has Report Quoting research, I have written that this is possible. Alberto Caballero, the sole author of the study, is an iPhD student at the University of Vigo in Spain. Caballero is no astrophysicist, but he wrote Wow! (Wow!) has published a study on the signal. It is also said about the wave signal that through this the aliens tried to contact the earth. This thing is from the year 1977. A narrowband radio signal was detected by a radio telescope in the US. This is known as the Wow signal.

Regarding the source of this signal that came half a century ago, scientists have speculated that it must have come from a Sun-like star located 1800 light-years away in the constellation Sagittarius. Many scientists believe that there is such an intelligent civilization in our galaxy, which wants to tell about itself. Probably he was the one who broadcast the signal.

In his research, Caballero calculated attacks on Earth, including the WO signal. This was then applied to the estimated number of exoplanets in the Milky Way. Caballero has come to know in his calculation that four civilizations can possibly attack the earth. He has warned scientists to be careful while practicing Messaging Extraterrestrial Intelligence (METI). Significantly, through this technique, efforts are made to contact other planets. Caballero fears that using METI in the wrong and excessive ways could provoke aliens to attack.
