A New Theory to Analyze the Mystery of UFO

The air rotates at high speed to form a tornado, which is "hollow". High speed rotating radiation can also form a hollow radiator. The formation principle of UFO is similar to that of tornadoes. UFO are radiators rotating at high speed. C/ ? Is the visible radius of the object( ? Is the angular velocity of the object's rotation), C/ ?= R is the radiation radius of the object. UFO is a hollow radiator. Its rotation speed is close to the speed of light and its propagation speed is very fast. UFO is a hollow radiator formed by radiation in a special environment. It is very difficult to form such a hollow radiation, so UFO is also rare. UFO can rotate at the speed of light, which is slightly lower than the speed of light. When the speed of light is much lower than the speed of light, the rotating radiator disappears and the radiation normally propagates in a straight line. The radiator is visible when its speed of rotation is less than the speed of light, and invisible when it rotates at the speed of light or faster than the speed of light, which is the truth of the UFO mystery.
