Why do inhabitants of other planets hear terrestrial radio signals?

The lack of equipment to sort and decode radio and television broadcast signals reaching Earth from other planets, and the same thing includes signals from Earth, is the reason these signals are not heard, says Alexander Banov, chief researcher at the Institute of Nuclear Physics at Moscow University, In an interview with the Russian news agency RIA Novosti, the SETI (Searching for Extraterrestrial Intelligence) project, which scientists are implementing in different countries to find intelligence on other planets, depends mainly on searching for radio signals from them.

According to Russia Today’s website, he said: “In order to receive such signals, humanity must have completely astronomical receivers, but these devices are not currently available, and the total energy of radio emissions from Earth equals the power of the sun, which means that suspicious radio noise can be detected In radio waves emitted by sources in the solar system, but we currently do not have equipment capable of analyzing radio noise to obtain a stream of useful information. "

It should be noted that the first transmission of radio signals was in 1909, and the first television broadcast started in the 1930s. This means that the radio waves that managed to penetrate the Earth's atmosphere launched into space 100 light-years ago, knowing that the size of the Milky Way is greater than 100,000 light-years.
