Foreigners can discover Earth airports from 200 light years

Humans may not know any smart beings outside the earth, but if they exist, They may already know about us. New research shows that radar systems in commercial and military airports unintentionally announce our existence to any foreigners with the ability to listen.

Initial results from a study led by Ramiro Kais SID, an astronomical physical doctorate candidate at the University of Manchester, indicate up to 200 light years, can discover in theory electromagnetic signals leaking from Global Airlines Centers such as John F. Kennedy International at New York Airport and Heathrow Airport in London. Military radar systems are also discovered, and thanks to their unique style, these signals will appear “clearly artificial for anyone who monitors distances between stars with strong radio telescopes” Caisse Saide ” He said In a statement.

“In fact, these military signals can appear to a hundred times from certain points in space, depending on where there is an observer,” he added. “The results we find indicate that the radar signals – which were unintentionally produced by any planet with an advanced technology and a complex aviation system – can act as a file A global sign of smart life“However, it is important to note that the signals that are located 200 years of airports, and the signals in this power can be since the 1950s, which can currently discover about 75 years in all directions, that the signals that are located 200 years of airports.

Since we live in an unforgettable vast world with billions of trillion planetary and moons, it is logical that we are not the only smart life forms in it. The desire of humanity to communicate with the Foreign Ministry Dates Return more than 150 years. The first real communication attempt occurred in 1974, when astronomers reference a radio signal from a strong transmission device at the ARCIBO Observatory in Puerto Rico to space. This reference, known as the ARCIBO message, consists of a dual code transfer Information about the basic chemicals of life, the DNA structure, the place of the Earth in the solar system, and even a human stick. If any of the foreigners receive, They did not want.

This did not inhibit the scholars from trying to find them. Those who work to search for intelligence outside the planet (SETI) do this negatively, The space is for electromagnetic signals This cannot be explained by natural phenomena. Others have followed a more active approach by deliberately transferring signals or messages to space, such as the ARCIBO message. These efforts are called (correspondence to intelligence outside the planet) or CETI (communicating with intelligence outside the Earth). Not everyone thinks this is a good idea. Critics note that telling foreigners where we can have severe consequences if these organisms are able to harm us or our planet.

This is a frightening idea. Perhaps the most fearful thing is the fact that the Earth is unintentionally screaming our existence and location for any civilizations outside the ground that discover the radar inside the ears. To get an idea about the loudness of our planet, Caise Saide and his colleagues simulated how radar signals from airports multiply over time and space, then they analyzed the extent of their discovery from stars like Star’s Star and Au Microscopii. These stars are nearly 6 and 32 light -year -old away from the sun, respectively.

They found that the airport radar systems, which sweep the sky to the air traffic control, send a strong common radio signal to detect it from up to 200 light years using telescopes similar to the Green Bank Telescope in West Virginia. This is a vast distance. The nearest potential for housing outside our solar system is just over 4 light years, and more than dozens of advanced spaces in humanity will remain from thousands of years to get there. Signals from the Earth’s military radar systems are weaker, but they are more concentrated and directed, creating a clear artificial style that resembles a beacon ray sweeps the sky.

However, it is important to note that it will take many years to reach any civilizations outside the planet located 200 light years away from Earth. Military airports and operations have not been just signs of this force since the fifties, and therefore, the maximum distance that foreigners can now discover about 75 light years in all directions. But the study point stands; Foreigners on a 200-year-old planet should be able to discover airport signals-but not for another 125 years.

Understanding the awareness of what our existence can be intelligent to our existence, can also help to direct our search for them, according to Caisse Saide. He said that identifying and describing our planet technologies, or signs of detected technology, can tell astronomers of what must be searched from other planets. At the same time, “we gain valuable visions on how to protect the radio spectrum of communications and the design of future radar systems,” said co -researcher Michael Garrett, professor of astronomical physics at Manchester University, in the statement. “The methods that have been developed can also be used for modeling and discovering these weak signals in astronomy and planetary defense, and even to monitor the effect of human technology on our space environment.”

In this way, our work supports both the scientific endeavor to answer the question. “Are we alone? “Caisse Saide” and the practical efforts to manage the effect of technology on our world and beyond, “said Caisse Saide.
