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, and enough paper and walls turned black. There is a treasure knife in the room, the blade part melts into iron juice, and the scabbard is still intact.
This is the magic of spherical lightning, which is what people usually say? Rolling thunder? , formed in thunderstorm weather. Spherical lightning is considered as a sphere of gas plasma, with an average diameter of about 25 cm and a long length of several meters. The color is often red, and sometimes blue-green spherical lightning can be seen.
Generally, the life of spherical lightning is only a few seconds, and the longer one is only a few minutes. It can move independently and slowly in the air, just like being controlled, which is amazing.
Most ball lightning will disappear quietly, while some? Lucky? When you come into contact with 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, and it 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 different opinions. Because it is rare, it increases the difficulty of research. In the science fiction novel Three-body, the author Liu put forward a strange conjecture, that is, spherical lightning is a kind of macroscopic electron with high selectivity to the target, so it produces? The knife melts but the sheath doesn't melt? Phenomenon.
Some people may want to know how to prevent ball lightning. The way is similar to the usual lightning protection, away from doors and windows, water pipes, unplugging power plugs and other metal conductors.
