Torchigin Vladimir 1938 Prof. was graduated from Moscow Institute of Physics and Technology in 1961. He puts forward in 2002 theory that nature of ball lightning is optical where a conventional white light that fell into a trap that it itself made for itself. All physical parameters and properties of such light have been derived from well-known laws of optics and physics. These properties are identical completely to mysterious and intriguing properties of natural ball lightning. At present 31 scientific papers are published in leading scientific journals on physics and optics.
There is currently no doubt that ball lightning is an optical phenomenon and is a bubble of light, similar to a soap bubble. It also exists for a limited time, disappears instantly and suddenly on an arbitrary section of its trajectory, leaving no traces. The only difference is that the shell of the light bubble consists of a thin layer of compressed air in which light circulates in all possible directions. The circulating light is not blown away by the wind, is not subject to gravity, and moves according to the laws of optics. This explains all the puzzles and anomalies in the behavior of ball lightning in the earth's atmosphere.
