Giant circles with many different shapes began to appear in the fields of England and remained the great mystery of humanity.
Crop circle - The circles on the field - the term used to refer to giant, large textures, which can be up to hundreds of meters, created on the fields due to falling trees, creating Contrast colors according to certain lines.
Most of these strange circles are concentrated in the south of England, especially in Hampshire and Wiltshire. There are also many circles recorded near Avebury and Stonehenge, two famous places with many mysterious stone works.
But crop circle is not only found in the UK, but also in many countries around the world, in continental Europe and outside like the US, Canada, Australia, Japan, India .
Crop circle is often shaped very accurately, and balanced, looking as if they are a product of machinery. The stalks are pinned down and bent but never die, and often lie along the whirlpool clockwise or vice versa.
The mysterious circles have been recorded in history books since the 14th century. In the following centuries, the crop circle's appearance was also reported scattered in many different areas.
But it was not until the 1980s, the crop circle began to attract the attention of the world when the appearance of a circle was widely reported by the press.
By the 1990s, the crop circle appeared more and more and became a phenomenon that attracted the attention of researchers as well as tourists.
The crop circle locations appear to have become a place attracting a lot of tourists from all over the world to visit and learn.
Initially, the crop circle was discovered only in a fairly simple circle form. But more and more they become more complicated later.
In addition to the single circle or the link of the circle, crop circle also appears under a lot of different shapes, sometimes very complicated.
They may also have a labyrinth-like structure, the shape of insects, patterns of ancient civilizations or types of writing that humans have never known.
Many crop circle has a structure that adheres to strict mathematical principles. Astronomer, the famous American professor Gerald S.Hawkins remarked that the 'people' creating cirle crop have a deep knowledge of Eculid flat geometry.
These mysterious circles usually appear from April to September each year, coinciding with the harvest.
They can appear on any crop such as wheat, rice, corn, beans, oats, tobacco or weeds and are completely shaped after just 1 night, outside of all human observations.
Who is the author of these mysterious circles? This is a controversial topic in the past decades.
Those who do not believe in paranormal phenomena think that this is just a man-made product to attract people's attention.
In fact, there have been many who claim to be the crop circle author and many such 'artificial' circles are made by mechanical means of media observation.
But those 'disgusting' circles always leave traces of human impact. While most of the circle surveyed by the scientist has absolutely no trace of vandalism, or is thickened. It seems that they are affected by an extremely powerful invisible energy.
Those who claim to have created the crop circle themselves cannot explain how to create such complex shapes. This has caused other speculation about the origin of the crop circle.
The most well-known hypothesis is probably an alien or a secret civilization whose level of development is higher than that of humans who created field motifs as a message to humans. .
Some scientists believe that crop circle is a consequence of whirlwinds, which are popular in the South of England. But this hypothesis is unconvincing because the whirlpool cannot create such perfect geometric structures.
Other comments suggest that the crop circle is created by the energy of the form of electromagnetic radiation emanating from the heart of the Earth. In fact, scientists have measured quite a strong magnetic field inside the circle. But it's hard to believe that natural energy has the imagination to create these butterfly-like motifs.
American researcher William Levengood discovered that crops in cropcircle appear to be damaged in the same way that they are placed in a microwave oven. It seems that they have collapsed due to sudden heat from the inside like energy in a microwave.
In 2001, two Dutch farmers claimed to have seen white light 'pillars' shine on their bean fields. After that, a crop circle appears where the light shines on.
In short, after decades of research, the phenomenon of 'circle on the field' remains a mystery to humanity. Hopefully, the correct answer to this phenomenon will be found in the near future.
