Several missions have been launched by multiple space agencies to search for aliens. But no space agency has made a breakthrough. Even though no concrete evidence has been found about their existence, experts and space agencies have not ruled out completely their non-existence. Many believe that the Milky Way is home to aliens. According to the latest study, it is highly likely that most aliens are dead. The study noted that since humans have failed to contact them despite making several efforts, the probability of their being dead is high. The study said that they might have died. Researchers said that aliens’ progress in science and technology could be the result of their destruction.
The study said that aliens may have emerged nearly eight billion years ago after the formation of the Milky Way. The Milky Way is nothing but a galaxy that houses the Solar System of which Earth is a part. The galaxy is believed to be formed approximately 13.50 billion years ago. Researchers said that they looked at the theory of science and technology to arrive at a conclusion that aliens could have been destroyed by their own progress. Researchers, however, didn’t rule out their existence. They said that if aliens exist, they are too young and located too far from Earth to be observed by humans. The latest findings of the existence of extraterrestrial life are crucial in determining whether a civilization can ever travel deep in space to meet the other.
Researchers said that they updated the 1961 Drake Equation to conduct the latest study. According to them, the older version excluded the evolving stellar properties. The study comes at a time when a team of scientists claimed to receive a radio signal deep from space. The signal likely emanated from a planet located is beyond the solar system. The source of the signal was about 51 light-years ago. This is for the first time when such a signal is collected by the Earth scientists.
