?Why have we not received any signal from aliens yet
Will we one day be able to discover any other civilizations in this universe? It is one of the most mysterious questions in the world of space. Our galaxy, the “Milky Way,” includes a huge number of celestial bodies, whose numbers range from (200 to 400 billion stars and 100 billion planets). Thus, there is a great possibility of the existence of life outside Earth in parts of this enormous universe. But why is there no clear evidence or indication of this? The existence of an intelligent civilization with which we can communicate?
The first person to come up with this question was the Italian physicist Enirco Fermi in 1950, when he asked his famous question, “Where is everyone?” , in what is now known as the Fermi Paradox. It turns out that there is a contradiction between the strong possibility of the existence of intelligent life, and the complete lack of evidence that intelligent life ever evolved beyond Earth.
While physicist Brian Cox, star of the TV series “Wonders of the Universe,” told The Sunday Times magazine, “There is only one solution to the Fermi problem; “It is impossible to manage a world that has the potential to destroy itself and requires highly collaborative solutions to prevent this from happening.”
This means that if a civilization reaches a certain size or development, it will automatically destroy itself in the end, either through wars and advanced weapons or as a result of environmental disasters. Cox warned our species at the end of his talk by saying, “The speed of development in the field of science and engineering may exceed that in the field of politics, which may lead to many contradictions and disasters. “It is likely that we are facing this possibility.”

Therefore, the answer to our question may be that these aliens may have exterminated themselves as a result of political unrest among themselves before they became advanced enough to travel between the stars and for us to communicate with them. Therefore, our search for them will be of no use, and we may be alone in this enormous universe.
