Some scientists call this phenomenon "self-immolation" and give a definition: the so-called "self-immolation" refers to the phenomenon that the human body is not in contact with external fire sources, and the inside burns into ashes, while all combustible materials around the ashes remain intact. Judging from more than 200 existing cases, the proportion of men and women who "set themselves on fire" is roughly equal; The age ranged from 4 months to 1 14 years old; The body is fat and thin, and some cases even occur in the process of walking, driving, boating and dancing.
So, what is the reason for "human self-immolation"? Opinions vary, and no one can agree. In the west, some people think that it is caused by excessive body fat. This explanation is obviously untenable, because people who set themselves on fire are fat and thin. Some people think that the self-immolation of human body is due to the burning of combustible substances in the body caused by some natural "electric fluid". What does the so-called natural "electrofluid" mean? Others think that spontaneous combustion is due to too much phosphorus in the body, which is unfounded. More interestingly, some people think that this is the phenomenon of alcohol spontaneous combustion caused by excessive drinking. The man also made a ridiculous experiment: injecting alcohol into a fresh piece of meat, but there was no "self-immolation" phenomenon.
In recent years, it has been pointed out that "self-immolation" is caused by spherical lightning in nature, so it is not spontaneous combustion, but spontaneous combustion. People who hold this view explain that ball lightning is like a big fireball, fluttering up and down in the air, which often surprises people who walk at night. Spherical lightning can pass through the cracks in doors and windows, enter the room and enter people's homes. Sometimes it will explode, destroy buildings and cause human and animal casualties. All obstacles encountered along the way are invincible, but you don't burn flammable things around you. Usually, the energy released by spherical lightning explosion is similar to that released by 10 kg TNT explosive explosion. Moreover, after the ball lightning disappears, it usually leaves the smell of burning, sulfur or ozone.
UFOs and ball lightning: Due to the mysterious and peculiar behavior of ball lightning, it has been suggested that most UFOs may be ball lightning. The reason is: as far as color is concerned. The colors of ball lightning are colorful, such as white, pink, orange and blue. UFO has a similar color; In terms of sound. Spherical lightning will make a slight squeak and crack when it moves, and finally disappear quietly. Because UFOs are far away, most of them can't hear the sound, but a few UFOs will make a whirring or rumbling sound when flying. Some UFOs also give off heat, which is consistent with ball lightning; Both UFO and ball lightning can float in the air, and their whereabouts are uncertain. However, people who hold different views think that ball lightning mostly happens in thunderstorm weather, while most UFO sightings happen in sunny days. Moreover, the movement of ball lightning in the air seems to depend entirely on the airflow, and the movement of UFO seems to be inconsistent with the airflow.
Spherical Lightning is a science fiction novel about spherical lightning by science fiction writer Liu. The book describes the arduous research mileage of a hero who has experienced ball lightning, and shows us a unique, mysterious and strange world. Spherical lightning is a form of lightning, also known as spherical lightning, which is often called rolling thunder by the people. The average diameter of spherical lightning is 25 cm, most of them are between 10 and 100 cm, the smallest is only 0.5 cm, and the largest is several meters. Spherical lightning occasionally has a ring or blue halo extending outward from the center, emitting sparks or rays. Common colors are orange or red. When it appears with particularly bright glare, you can also see yellow, blue and green. Its life span is only 1 ~ 5 seconds, and it can reach several minutes at the longest.
The walking route of spherical lightning generally falls directly from the sky, and suddenly changes direction and moves horizontally when approaching the ground; Some suddenly appear on the ground and bend forward; There are also those that roll along the surface and rotate rapidly; The speed of motion is often 1 ~ 2 meters per second. It can enter the building through doors and windows, usually through chimneys. It can even slide on the wire and sometimes make a "buzzing" sound. Most fireballs disappear silently, and some will explode when they disappear, which will cause damage and even collapse buildings, causing human and animal deaths. People will have an amazing explosion when they meet something, producing a pungent smell, causing casualties, fires and other accidents.
The way to prevent ball lightning is to close doors and windows in thunderstorm weather to avoid direct flow. If you encounter a floating "fireball", avoid it gently and never touch it. Scientists speculate that spherical lightning is a gas vortex produced at the sharp turn of lightning path, which is a gas mixture with high charge, mainly composed of oxygen, nitrogen, hydrogen and a small amount of hydrogen oxide. It usually happens after dendritic lightning, and it seems that dendritic lightning is a necessary condition to produce spherical lightning. Ball lightning is rare, so it is very difficult to study, and it is still a mystery in nature.
