What does science say about the fees that appear on farms?

First reports from Graphics set in crop History from the Middle Ages. In the most recent history, a file was crop circles It became popular in the 1980s, when various forms began to appear on the wheat and other grain fields of Scotland and England. Made from flattening vegetation, these images sparked curiosity and many theories about its origin began to circulate, as they still are today.

Until 1991, two artists claimed to be authors of drawings. For a British newspaper, friends Doug Bauer and Dave Corley revealed that they’ve made more than 200 pieces in the past decade, using boards and cut ropes. The boards were used to knead the farm, while the ropes ensured that the movements were more precise, to leave more beautiful pictures.

A year later, a competition for crop circles was held in the country, another name given to crop circles. The competition was supported by newspapers Watchman And the Grain worldas well as a German scientific journal.

Participants included Cambridge University students, students at a local school and even a pair of women accompanied by a Pyrenean mountain dog, which has been specially trained to pull up planks.

The experience was crucial. Humans could already create all the patterns found in crop circles at the time; 11 of the 12 teams that achieved reasonably great lineups followed the proposed design,” said one of the competition organizers in a 2010 publication.

Nevertheless, crop circles continue to intrigue and provide fuel for the human imagination. This week, city ipuaçuinside of Santa Catarinavia huge geometric shapes drawn in a wheat field, photographed and posted on social media.

This isn’t the first time something like this has happened in the state: In Iboisso alone, crop circles have been spotted at least four more times since 2008, according to the city council.

The crop circle images are nothing known, which adds an aura of mystery to the graphics. Since the first crop circle was found in 2008, the city of more than 7,000 has become a popular destination for ophthalmologists, who attribute the inscriptions to the activity of extraterrestrial beings.

According to the city council, Iboiso became known as “Its City”. Pictures recorded in different years vary in size, measuring between 19 and 44 meters.

Among the specialists from various fields, it is difficult to find anyone who would support the hypothesis of extraterrestrial artists, leaving paintings in the rural areas of the interior of Brazil. According to Adolfo Stutz-Neto, an astronomer and chair of the Astronomical Studies Group (GEA) at the Federal University of Santa Catarina, the technique Bower and Chorley used in the 1980s is still used to create crop cuttings.

Historian Hernan Mustago was fascinated by optics as a teenager, and it was precisely the image of a crop circle he saw on the cover of a magazine that made him plunge into the universe, which he now considers “more fiction than real.” “Ufology has been treated for decades with many inventions, many conjectures, focused on plot and little scientific merit,” points out, director of the International Museum of Radiology, History and Science, located in Itaara (RS).

He points out that this is not about denying the existence of extraterrestrials: “We have a huge potential for a universe full of other life, the new James Webb telescope shows the atmospheres of exoplanets where the possibilities for life are promising. But the big question is: is this life so intelligent that it can reach here on earth?”

The same question was asked by Professor Adolfo Stutz-Neto, who explained that in order for an object from another astronomical system to reach here, it would need to face a journey of about 50 trillion kilometers, which could take up to 600,000 years. “If you had the technology for that and a body that could withstand the journey, why would you leave a drawing in a wheat field and leave?” , He said.

In addition to intentional human actions, there are natural processes that can cause crops to flatten. This phenomenon is called AccommodationIt is characterized by falling or bowing plants. According to agronomist Luiz Henrique Skodowski, it may be related to plant growth or influenced by various factors. “When a plant grows a lot, it falls, for example, with heavy rain and wind. These are the conditions that “force” it to sleep,” he explains.

Among these are the genetic characteristics of plants, such as the thickness of the stem; the strength of their covers (the part that connects the leaf to the stem); height and weight of your upper body; Forms of management and characteristics of production. In variables related to production, the agronomist cites the number of plants per meter, since the more there are, the more they need to stretch to get sunlight; The amount of roots that support the culture and support the population, which occurs when one plant “carries” the other.

To the eye, the lodging appears to have been done by the force of an external factor, but it is a condition that generates random flatness that can create different kinds of patterns in the farm, such as maze-like circles and lines. This distinguishes the naturally generated graphics from those seen in Ipuaçu, for example. Skodowski highlights “These specific cases, in which configurations are geometrically perfect, are manual actions.”

For the astronomer Adolfo Stutz-Neto, another point is added to the conclusion that motion pictures are human work: first, pictures are always made in grain and cereal crops such as wheat and barley, which are easy to crush and do not return to their original origin. positions.

Historian Hernan Mustago, who had already conducted studies in Iboisso at the time of the emergence of other forms of agroglyphs, adds one more: the absence of any radioactivity in the soil or changes in the structure of plants: “If something is supposed to be extraterrestrial on Earth, Perhaps it brings radiation different from normal terrestrial radiation, both in plants and in the soil.”

But the only change noted in the city was the flattening of the crop. He argues, “Something that any man can easily do.”
