Crop Circles are geometric patterns that appear mysteriously in crop fields. The crop is not cut, but is usually laid flat and most often swirled into an attractive floor pattern. Most patterns appear in cereal crops such as wheat and barley, but circles have been known to occur (in lesser numbers) in oilseed rape, maize, linseed, grass and even borage - to name a few. In the US many circles appear in soya, as it grown prevalent in that part of the world.
Location
Although it might seem obvious, crop circle occur only during the crop growing season. In the UK the first circles can start to occur in April and May, reaching their height in late July and August. Crop circles do in fact occur all over the world in many countries and obviously they similarly follow growing seasons in that particular part of the world.
In the UK most circles occur in the county of Wiltshire, although circles do happen (in lesser numbers) countrywide. In the early season (April/May) numbers are few but this gradually builds up as the summer moves on, at the height of the season (Late July/August) several circles can appear on one night. The season ends with the harvest - and the slate is wiped clean for another year.
The crop circles do seem to have an affinity for ancient sites. Many circles appear close to stone circles, barrows, earthworks and other landmarks. Stonehenge and Avebury have played host to many crop circles over the years.
Mowing devil
There is an ongoing debate between researchers as to the longevity of the phenomenon. Essentially two camps exist within the debate; those who believe that the crop circle phenomenon is a relatively modern occurrence beginning in the mid 1970's and those who believe that there are reports going back to the beginning of the century and even earlier. The first circle photographed (documented) in the UK was in 1976, however many farmers report circles in their fields going back considerably further than this date. There is a woodcut dating back to the 1600's known as the 'Mowing Devil' which seems to show some kind of circular pattern in a crop field, however opinion is divided as to whether this can be directly linked to the crop circles or not.
Designs
Crop circles are not just circles -- they can come in many different shapes. The most basic (and the most common) crop circle is the single circle. Circles may also come in sets of two (doublets), three (triplets) or four (quadruplets). Circles also may be enclosed in a thin outer ring.
The stalks inside a crop circle are typically bent into what is known as a swirl pattern, and the circles may spin clockwise or counterclockwise. In patterns with several circles, one circle may spin clockwise and another counterclockwise. Even a single circle may contain two "layers" of stalks, each spinning in a different direction.
Crop circles can range in size from a few inches to a few hundred feet across. Most early crop circles were simple circular designs. But after 1990, the circles became more elaborate. More complex crop patterns, called pictogram's, emerged. Crops can be made to look like just about anything -- smiling faces, flowers or even words. Crop circles are sometimes unique designs, but they can also be based on ancient motifs.
Some of the more sophisticated patterns are based on mathematical equations. Astronomer and former Boston University professor Gerald S. Hawkins studied several crop circles and found that the positions of the circles, triangles and other shapes were placed based on specific numerical relationships. In one crop circle that had an outer and an inner circle, the area of the outer circle was exactly four times that of the inner circle. The specific placement of the shapes indicates that, whoever the circle makers are, they have an intricate knowledge of Euclidean geometry (the geometry of a flat surface introduced by the mathematician Euclid of Alexandria).
Some circles have thin lines leading away from them. These lines, called spurs, are not actually a part of the circle. They are created by the farmer's tractor.
ALIENS BEHIND THAT
Some cerealogists (people who study crop circles) say that these diagrams must be created by intelligent alien beings from elsewhere. Even though these diagrams must be constructed in a very short time span, the genuine crop circles never show any serious mistakes or blunders of execution. Cerealogists see this as evidence that the aliens must be very intelligent and much more advanced than we are. That's mere speculation, of course. Others say the real reason is that there's a worldwide conspiracy to hide the fact that the aliens sometimes do make mistakes. This cover up is carried out by people who want to preserve the myth that the aliens are a perfect race. The fact that you've never heard of such crop circle blunders just shows how effective this cover up is, they say. Mistakes are repaired at the site, or sometimes photographs of the circles are retouched. This has about as much to recommend it as any of the other conspiracy theories accepted and believed by simple-minded people.
They might be want to send some type of message to the human being. Take a look at our thinking about them, we send golden coin plate via voyager by thinking that if anyone exist on that planet or moon and they can understand that message and can know that aliens visited their place. Some kind of same thinking may be they following.
Extraterrestrial may be trying to communicate in big way.
Voyager record plate :
Send via Voyager on other planets which it visited within its journey. If we can send some type of unexplained message to the other life then why they can't?
People who agree with this theory say that the circles are either the imprint left by landing spacecraft or messages brought from afar for us earthlings. Some eyewitnesses claim to have seen UFO-like lights and strange noises emanating from crop circle sites.
Gaia
many have related crop circles to spiritual reformations of the Gaia hypothesis, claiming that "Gaia", the earth, is actually alive and that crop circles are messages or responses to stimuli such as global warming and human pollution. It asserts that the earth may be modeled as if a single super-organism, in that earthly components (e.g. biota, climate, temperature, sunlight, etc.) influence each other and are organized to function and develop as a whole.[44] Responding to local beliefs that "extraterrestrial beings" in UFOs were responsible for crop circles appearing, the Indonesian National Institute of Aeronautics and Space (LAPAN) described crop circles as "man-made". Thomas Djamaluddin, research professor of astronomy and astrophysics at LAPAN stated: "We have come to agree that this 'thing' cannot be scientifically proven. Among others, paranormal enthusiasts, ufologists, and anomalistic investigators have offered hypothetical explanations that have been criticized as pseudoscientific by skeptical groups and scientists, including the Committee for Skeptical Inquiry.
Doug Bower and Dave Chorley
In 1991, self-professed pranksters Doug Bower and Dave Chorley made headlines claiming it was they who started the phenomenon in 1978 with the use of simple tools consisting of a plank of wood, rope, and a baseball cap fitted with a loop of wire to help them walk in a straight line. Inspired by Australian crop circle accounts from 1966, Doug and Dave reportedly made more than 200 crop circles from 1978–1991 and claimed to be responsible for most if not all circles made prior to 1987.After their announcement, the two men demonstrated making a crop circle. Despite general acceptance of their story, crop circle researchers remain skeptical of many of their claims, due to the complexity of some circles, absolute precision, size (some were 1 km wide) and time required to be done. After their revelation, crop formations started appearing in countries all over the world, increasing in number, size, and complexity.They are most likely made by imitators of Bower and Chorley.
Witness view :
LIGHT FORMATION
In August 2001, two witnesses in Holland saw "columns" or "tubes" of white light descend into a string-bean field. Shortly after they observed this light, they saw a new crop formation exactly where the light had descended. For a simulated image, see BLT Research: Eyewitness Report.
ENERGY EFFECTS
People close to the sites of crop circles have had some strange physical and emotional reactions. Some have reported feeling dizzy, disoriented, peaceful or nervous. Others have said they heard a buzzing noise or felt a tingling sensation. After visiting the Julia Set formation near Stonehenge in 1996, a group of women reported changes in their normal menstrual cycles. Most startling was a small group of post-menopausal women who suddenly began menstruating again after visiting the site.
Experimental results :
After studying the soil samples and grain dispersion pattern it is concluded that it would be highly impossible that all of these designs to be man-made. The pattern is experienced from the sky only hence logically its very difficult to produce such a designs for human being within less time span.
Spinning plasma vortex (William Levingood)
The plasma vortex theory took a back seat for a while, until Dr. William Levengood redeveloped it into a much more radical and encompassing view. Levengood attempted to explain the microwave energy and other residues he had found in grain samples taken from crop formations. In fourteen years of scientific investigation on crop circles, Levengood has examined more than 250 crop formations in detail. Since 1992, he and his team have been involved in extensive on-the-ground surveillance and the collecting of samples and electromagnetic and other readings from crop formations. These samples are then sent to Levengood for analysis in his private laboratory based in Michigan, where he compares the grain collected from in and around the circles with control samples taken from edges of the fields the formations were found in.
William Levingood :
The first scientific attempt to explain the appearance of crop circle formations was put forward by Terence Meaden, a physicist and meteorologist with master's and doctorate degrees from Oxford University and a Fellow of the Royal Meteorological Society. In addition, Meaden is the founder of the tornado study group TORRO, which collects, analyzes, and publishes data on the incidence, strengths, and origins of tornadoes and severe storms.
Messages from crop circles :
According to researchers extraterrestrials want to send some kind of message to us. That may be about earth, any further disaster or anything. We don't know who are they and who are delivering that . They may be higher intelligence who want to communicate with us in this manner.
