Crop circles, first appeared in 1647, in England; has a long history with 365 years. But they did not gain much attention until the first modern crop circles appeared in Britain, in 1972. From them on, more than 2000 such circles appeared in the fields all over the world, expect South Africa.
The shapes of those circles are different, but nearly all of them are symmetrical; and they are becoming more and more complicated. These strange phenomenon
ysicists, as well as aroused people’s interests: many scientists, geographers, ph
organizations devoted themselves to find out how these amazing works came out. Unfortunately, until now, no one could make a convincing explanation for how those circles formed. In general, there are 6 explanations: the first one is the earth’s
magnetism, which is said that it is the magnetism from the earth that makes them. The second explanation is the effect of tornado. The third one is about prediction which people believe that those circles are the premonition of some kind of disaster. Also, like other strange appearances, some people believed it is the masterpiece from the creature outside the earth. Still some think they are constructed by human beings as a prank. And the last one is high frequent radiation theory.
As far as I am concerned, the most unconvincing explanation is the man-made theory: firstly, I can’t image that human beings could make such huge complicated
project in such a short time without any vestiges. Secondly, there were many physical characters that appeared in those mysterious circles, like strengthen of infrared ray, which oppose to the theory. Also, according to the physical characters and the well-made shapes, I doubt the tornado explanation. Still, the prediction theory is
ridiculous to me, because, in my eyes, every phenomenon occurred in some specific reason, we can not simply attribute them to prediction when we can not explain. As for the other three theories, I think they’re both possible for some reasons.
In a word, people still can not tell exactly how those circles appeared; as the time goes, I hope that we could finally find out the reason why they occurred.
