A group of American astronomers led by Frank Drake came to the conclusion that if Earthlings receive signals from extraterrestrial civilization, aliens are likely to be already dead. This is written by Science News. The researchers calculated the area of that area of the galaxy through which the alien signals must pass. According to Drake, civilizations are born and die at a constant rate, but the radio signals sent by them continue to spread in all directions along the Milky Way. As a result, most of the galaxy is filled with messages from dead aliens. The Milky Way’s diameter is one hundred thousand light-years, while the solar system is located about 26,000 light-years from the center of the galaxy. Scientists believe that most developed civilizations capable of sending radio signals do not exist for more than one hundred thousand years. Therefore, the chances of receiving a message from aliens still broadcasting at the moment are very small. Humanity sends signals to space for about 80 years, so radio waves from Earth have covered less than 0.001 percent of the area of the galaxy. Back in 1960, astrophysicist Frank Drake proposed the same name formula, allowing to estimate the number of highly developed civilizations in the universe. There are various solutions to this equation, but the values of most parameters in the formula are based on assumptions. More important news in the Telegram channel «The ribbon of the day» .
