In an effort to discover intelligent a̳l̳i̳e̳n̳ life, Carl Sagan sent a transmission known as the ‘Arecibo’ message into space via radio waves.
The message addressed to intelligent ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ beings was the most powerful radio transmission ever transmitted to space by humanity.
By comparison, the signal sent into space was a million times stronger than a typical television broadcast.
Aimed at a group of stars located more than 25,000 light years away, the pictorial message was sent in the hope that one day we would receive a similar response from another c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳.
The radio signal included the location of our planet Earth within our star system, the basics of mathematics and science, and the type of antenna that was used to relay the signal – all characteristics that an intelligent a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ should understand. .
The message prepared by Carl Sagan and his colleagues also included information about our species, our music, even our physical appearance was included in the radio message, as well as in our ĎŇÃ codes.
A few years after the signal was sent, people forgot about it. Then, 27 years later, already in 2001, a ” Crop Circle ” that is, a crop circle appeared shaking the scientific community.
A pattern appeared in a farm field, right next to the UK’s largest telescope and observatory, the Chilbolton, where the world’s largest fully addressable weather radar is located, and the surprise was that it looked like a response to the transmission sent. way back in 1974.
It was considered by many to be one of the most impressive and important crop circles ever to appear on our planet, as this circle, unlike others, carried a message direct from space.
While many dismissed the crop circle near Chilbolton as yet another hoax, analysis showed that it carried a message, or rather a response from another c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳.
Describing a different solar system in the universe, the emitter image, non-human ĎŇÃ, and some microwave antennae, the Chilbolton Crop Circle was the final answer we had always hoped for.
Incredibly, just a year before the ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ message was discovered, in the year 2000 a circle of unknown shape appeared alongside Chilbolton.
A year later, the puzzle was put together, and we could see that the crop circle that appeared in 2000 was, in fact, a representation of the microwave telescope used to transmit the signal to us.
In 2001, three days after the mysterious answer appeared alongside Chilbolton; another crop circle was found depicting what appeared to be an a̳l̳i̳e̳n̳ face.
According to the librarypleyades.net portal, the decimal equivalents of the binary code were not modified with respect to the original ‘Arecibo’. But the atomic numbers of the elements that make up the basis of life had been altered:
Silicon, an element with an atomic number of 14, was added in precisely the correct sequence: between oxygen (atomic number 8) and phosphorus (atomic number 15).
In 1969, the late Ben Volcani, a renowned microbiologist at the Scripps Institution of Oceanography, discovered the crucial role of silicon in carbon-based life.
His work and that of his colleagues (such as Charles Mehard, also at Scripps, and Edith Carlisle in the 1970s at UCLA) demonstrated that the presence of silicon is critical in a variety of terrestrial life forms, as well as in the structure of human cells: example, in the union of cartilage and mineral aspects of bones.
It remains to be debated whether the crop circle that appeared alongside Chilbolton was, in fact, an ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ response.
However, many people are firmly convinced that not only is the 2001 Chilbolton an actual message from another intelligent a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ in the universe, but we receive similar messages almost every day.
