What is spherical lightning like in reality? Spherical lightning, commonly known as rolling thunder, is a spherical lightning ball. This is a real physical phenomenon, not an energy cannon of science fiction or comic series. This phenomenon was recorded as early as 1838. Scientists have studied it for 160 years and published thousands of related reports and more than 2,000 scientific papers. However, we still have no reasonable explanation for this phenomenon, but it is not credible to say that it can cross any object. Spherical lightning usually appears in thunderstorm weather. It is very bright, slightly spherical and about 20 to 50 cm in diameter. Usually it lasts only a few seconds, but there are also 1-2 minutes. Even more amazing, it can move independently and slowly in the air. Some witnesses said it would follow metal objects, such as telephone lines, but most people said its path was uncertain. Most witnesses said it moved horizontally. In its short life of a few seconds, its luminosity, shape and size remain unchanged. It has appeared in open spaces, closed rooms and even airplane cabins! There are signs that it is closely related to lightning between clouds and the ground (that is, common ordinary lightning), and witnesses say it will form or disappear after ordinary lightning. Spherical lightning may explode violently, or it may suddenly disappear quietly. In terms of color, opinions vary and there is no consistent description. Spherical lightning is destructive. It can not only destroy the glass window, but also make the outer layer of the wall peel off. It also caused human and animal casualties, but due to insufficient information, the real cause of death has not yet been known. There is no evidence that ball lightning will destroy trees, which is slightly different from ordinary lightning. Spherical lightning can hardly be destroyed Someone once used a rifle to shoot ball lightning, but it didn't work. Because of the low frequency of spherical lightning, it is difficult for scientists to make systematic observation, and no one has taken high-quality photos for scientific research so far. Theoretically, some people think it is a hot air mass or a vaporized element, such as carbon, sodium or copper. Although this theory can explain some characteristics of spherical lightning, it can't explain why it can form in the aircraft cabin. In addition, there are many different theories, such as plasma, ions, charged dust, and water with an outer electron layer, but none of them can fully explain this scientific unsolved case. If you have ever seen or taken photos of ball lightning, be sure to record all the information! That will be very valuable research data. Spherical lightning is mysterious because it is not common. Its ethereal whereabouts, changeable colors and shapes, and its great destructive power to stop time fascinate human beings. Therefore, as early as ancient Greece, people began to pay attention to this strange natural phenomenon.
