Spherical lightning is a normal natural phenomenon. In Dream Stream, Shen Kuo once described:? Li Shunju, the chamberlain, was once shocked by violent thunder. In the west room of the hall, thunder and fire came out from the window and suddenly came out of the eaves. People thought that the hall had burned, so they all avoided it. When the thunder stops, the house is natural, and the wall and window paper are all in Guizhou. ?

this phenomenon was very magical at that time. Generally speaking, people think that all the places where lightning passes are ashes. Unexpectedly, the things in the room were not destroyed, so the enough papers and walls turned black. There is a treasure knife in the room, the blade is partially melted into iron juice, and the scabbard is still intact.

this is the magic of spherical lightning, which is usually called by the people? Rolling thunder? , formed in thunderstorm weather. Spherical lightning is considered to be a sphere of gas plasma, with an average diameter of about 25 cm and a large length of several meters. The color is often red, and sometimes blue and green ball lightning can be seen.

Generally, the life of ball lightning is only a few seconds, and the longer one is a few minutes. It can move independently and slowly in the air, as if it were controlled by people, which is very magical.

Most ball lightning will disappear silently, but some? Lucky? When you touch people or things, that is, some conductors, the internal balance is destroyed and huge energy is released. Therefore, spherical lightning is harmful to some extent, which is fatal to people and animals.

In fact, there are still many puzzling places about the cause and internal composition of spherical lightning, which are still under study. People are controversial and have their own opinions. Because it is rare, it increases the difficulty of research. In the science fiction novel "Three-body", the author Liu Cixin put forward a strange conjecture, that is, ball lightning is a macroscopic electron with high selectivity to the target, so it is produced? The knife melts without the scabbard melting? The phenomenon.

some people may wonder how to prevent ball lightning. The way is similar to the usual lightning protection, away from metal conductors such as doors and windows, water pipes, unplugging power plugs, etc. If you encounter it, avoid it gently to avoid air disturbance, otherwise it may pounce? Bite? Yes.
