"At about 9 o'clock on August 5, 2014, in the Water Conservancy and Water Protection Bureau of Xindai County, Shanxi, with a thunderclap, in an instant, a red bright light flashed into the corridor, breaking into the laboratory from the plastic steel window without a protective fence, the speed was very fast, and disappeared with a roar.
According to the description of the parties, the diameter of the bright light is about 40 centimeters, which should have been an explosion, which was very loud at the time, and also caused different degrees of damage to 5 computers. ”
Afterwards, Yang Ying, a meteorological lightning protection engineer at the Meteorological Bureau of Xindi County, made a detailed analysis of this and judged that this bright light was a very rare "ball lightning" in history, commonly known as the rolling mine.
Due to the rarity of the rolling mine phenomenon, the existence time can only last for a few seconds, of course, there are records of 1 to 2 minutes.
However, the frequency of ball lightning is very low, scientists are difficult to make systematic observations, most of the records are basically eyewitness oral accounts, and even whether it exists has not been accurately verified.
Many scientists around the world dreamed of being able to capture a real image of ball lightning, but in the end they failed to achieve it.
In 2012, the mystery of this ball lightning that has puzzled dozens of generations of scientists was finally unveiled for the first time by Chinese scientists.
At about 9:53 p.m. on July 23, 2012, researchers at Northwest Normal University in Lanzhou accidentally recorded an elusive glowing ball while mapping radiation during a thunderstorm in Qinghai Province.
The ball of light rises from the ground, travels 15 meters on the ground, and then disappears. The researchers say its luminous range is about 10 meters in diameter and only appears for 1.64 seconds. The video and spectra of the storm, which took place in 2012, are believed to be the first scientific record of ball lightning in nature to date.

After its publication in 14 years, the report was rated by the American Physical Society as one of the eight major advances in physics, which confirmed the true existence of ball lightning and provided important clues as to how ball lightning existed.

This time, researchers at Lanzhou Northwest Normal University used spectroscopic equipment to record ball lightning, so that the main elements that make up ball lightning can be identified. They found that ball lightning contains iron, silicon and calcium, which are the same as the main components of soil, so whether ball lightning is lightning or not remains to be investigated.
So xiao j guessed from a non-professional point of view that ball lightning could be an ordinary lightning bolt hitting the ground, due to the high energy, resulting in the gasification and combustion of the elements in the soil?
Of course, although we have real videos and spectra of ball lightning today, because ball lightning is too rare and opportunistic, it is still very difficult to study it, and it is still a mystery in nature today.
Some people think that the ufo that someone in our life witnesses is probably the ball lightning here, what do you think of it in front of the screen? Welcome to leave a comment in the comment area.
