until now there has been no definite answer how they are formed.
Crop circle is a circle and other shapes such as geometry (and plumpness large / wide), even some that are commonly encountered form the image of living creatures such as scorpions, sunflowers, bees, etc.
the fields of agriculture, especially wheat. In the UK, Canada, USA, Australia and Japan, many found the phenomenon of crop circles. This phenomenon usually occurs in the summer when farm fields overgrown with plants .. Geometry is sometimes in the form of circles or can also form a unique series of images, which show that the author is an intelligent creature. But, this is not a crop circle made by humans based on a variety of evidence that has been investigated by scientists.
Here's the explanation :
Human actions
Actually hard to believe if human actions. Quite a lot of them think, that what is called circular wheat fields was not more than one fraudulent act. According to scientists from the UK Anderro that has investigated while researching this phenomenon for 17 years, that there are about 80% circle wheat fields that are man-made. A British national has told the media that he and some friends are making a circular wheat fields in London, England. Previously they had been preparing design drawings, when nearly ripe wheat in the fields, with a long nail dipantakkan in wheat fields, and the nail was used as its center, then, circling the ground with a rope, then came a wheat field circle. The problem is, is it possible he could make a circle in one night without adequate tools? then made for what purpose?
Magnetic field :
Some strange circle has been sidelined likely due to human activities. Because the structure of their images (strange circles) complex, large size, beautiful design, was not the result of man-made that can be done overnight. Although Anderro insisted that 80% of the wheat crop circles are man-made, however, he also believes that the remaining 20% is a natural formation due to the effect of Earth's magnetic field. In a magnetic field there is a supernatural power of motion, can produce an electric current, so that the plant "lay flat" above ground level. Relevant experts from the U.S. that Jeffery Walson has researched over 130 circular wheat fields, and found that 90% around the circle there is a strange transformer associated with high voltage cables. Under a long line along the circumference of 270 meters there is a pool, because in-watered, the ions are removed soil from the bottom of the wheat fields can generate electrically negative, while the transformer is connected to the high voltage wires produce positive elekrik. After the negative and positive electrical contact to produce electrical magnetic energy, then tear down the grain and form a strange circle. However, they can not provide all the answers of the question how the odd shapes that can be formed? Is it possible that energy can take the form of flowers or a scorpion?
Tornado winds :
According to physicists at the University of Michigan, USA that is Dr.Delon Smith, that the erratic changes in the summer, tornadoes are the main reasons that caused the strange circle. Through his research he found that a large number of strange circles in wheat fields that appear on the side of a mountain or areas within 60-70 km of the mountain, where a place like this is a place that is easy to form a tornado. But if a tornado can make a circle with a certain precision is?
Or artificial extraterrestrial most recognizable Aliens ..
Many believe, that most of the strange circles in the wheat field is formed in one night, chances are the work of extraterrestrials. Since 1990, photographer Alexander said, he saw a strange light in the wheat fields, the light was flying here and there in between the two circles weird. The existence of aliens in the stomachs of wild ducks in San Francisco United States may reinforce this notion.
Heterodoxy (discordant views)
Some people believe, that behind the circular wheat fields there are various kinds of supernatural powers, so rich in the Bermuda triangle. According to these allegations, there is a strange circle and then call it a "disaster notification", so as to spread the discordant views that deviate from orthodox teachings. Why strange circles often appear there? And now, a circle that never appeared in a sunflower field, Russia, then why could that be? Maybe we can just wait for scientists to uncover more.
New in 1991, appeared the first recognition of crop circle makers. He admitted to making crop circles to spread rumors about UFOs. Even so, the explanation still leaves the question among scientists: how could such a work of art made without leaving the slightest trace, and usually can be completed in one night.
In his explanation, Richard Taylor denied the use of a number of traditional instruments that may be used to make crop circles. "In modern times, the use of boards and ropes to lay the plants and benches to jump from one area to another so as not to leave a trail, it is too troublesome to get results in a short time," said Taylor.
According to Taylor, crop circle makers can use high-tech devices, such as GPS devices to place the shapes and magnetrons, tubes that use electricity and magnetism to generate intense heat, to lay down crops with high speed.
Although impressed valid and plausible, explanations Taylor not necessarily be accepted, until there is a crop circle makers who want to explain the tricks of manufacture. Even so, Taylor's statement published in Physics World this could be used as a reference.
"Taylor has been acting as a good scientist, examine the facts related to the design and construction of crop circles without getting carried away current UFO, gossip, and aliens," said Matin Durrani, editor of Physics World
