JJ von Littrow lost sight of the implementation of his idea. However, even many years after the presentation of this ambitious plan, people did not stop trying to make contact with life forms outside of Earth.
So what messages did people send to aliens? Livescience.com is examining attempts to connect with alien civilizations.
Radiocommunication has become, as was thought, a means to fulfill the desire to announce the existence of the Earth. In 1962, Soviet scientists aimed a radio transmitter at Venus and greeted the planet using Morse code. This first such introduction consisted of three words: mir (a Russian word meaning peace or the world), Lenin, and the USSR (an abbreviation of the name of the Soviet Union written in Cyrillic in the Latin alphabet). The message was considered essentially symbolic, positive in 2018. In an article published in the International Journal of Astrobiology. It was more like a test of an entirely new space radar. It is a technology that sends radio waves into space. Its main purpose is to observe and display objects in the solar system.
In terms of distance, the next attempt to reach alien civilizations was much more ambitious. 1974 A team of scientists, including astronomers Frank Drake and Carl Sagan, broadcast the Messier 13 radio message from the Aresibo Observatory in Puerto Rico for $ 25,000. to the star cluster in the light years. The image message sent in binary code included a graphic human figure, a graphic DNA double helix structure, a carbon atom model, and a telescope diagram.
“The Aresibo message is an attempt in mathematical and scientific language to present a generalized image of who we humans are,” explains the psychologist and the non-governmental research organization Messaging Extraterrestrial Intelligence International (METI), which creates and transmits messages aimed at connect with alien civilizations, President Douglas Vakochius.
Aresib’s message in the literal sense of these words was shots in the dark. It would take about 25,000 to reach Messier 13. light years. But by the time the message arrives, the swarm of stars will have already moved, says the Department of Astronomy at Cornell University. Hypothetical aliens still have the ability to detect a penetrating signal: its intensity is 10 million times stronger than radio signals sent by our Sun (the Sun emits a wide spectrum of electromagnetic radiation, from electromagnetic waves to radio waves) . However, this is unlikely, says Seth Shostak, an astronomer at the Search Institute for Extraterrestrial Intelligence (SETI).
“It just came to our attention then. It’s like a giant billboard that was supposed to be on the road, but it turned up somewhere in the fields,” Shostak explained to Live Science.
Until recently, radio signals were used to transmit everything from art to advertising. According to an article in the International Journal of Astrobiology, in 2008 Doritos broadcast his announcement in the direction of the Great Wheels of the Turtle: the radar signals were aimed at one of the constellation’s solar systems, 42 light-years away. In 2010, a message written in Klingon (an artificial language spoken by aliens from Star Trek) invited real aliens to participate in a Klingon opera in the Netherlands.
Attempts to connect with aliens were not limited to radio. Spaceships with ground artifacts also set sail, hoping that they would eventually be trapped in space by representatives of extraterrestrial and intelligent life forms. 1977 The Voyager 1 and Voyager 2 spacecraft launched in 2006 to explore the farthest corners of our solar system and interstellar space. Both ships have a golden disc, a message from humanity, consisting of things like music, ambient sounds from Earth, and 116 images of our planet and solar system.
Voyager probes are still flying in interstellar space and waiting for someone to discover them. But what is the probability of this happening? “Zero,” says Sheri Wells-Jensen, a linguist at the University of Bowling Green, who specializes in extraterrestrial civilizations.
“It is a beautiful and poetic decision, a fascinating and bold attempt to bring together the best descriptive elements of humanity, although, in terms of actual communication, it did not make sense,” says Sh. Wells-Jensen.
Experts agree that the chances of any of the attempts reaching alien civilizations are slim. Of course, that result would depend on the presence of other life forms in our solar system. But representatives of those life forms whose existence we do not know should also listen carefully to radio signals and have enough knowledge of mathematics and science to understand the messages we send. Furthermore, the messages we send essentially assume that these aliens perceive the universe in a similar way to us: through sight and hearing.
However, this does not mean that all those messages are meaningless. “It just came to our notice then. So why shouldn’t they look? Sh. Wells-Jensen. What if our messages to these hypothetical beings are unreadable? No big deal.” It seems to me that the most important thing we have said it’s that we exist in general, “said Sh. Wells-Jensen.
