Ball lightning is known as the most magical and mysterious natural phenomenon in the world, which has puzzled the scientific community for hundreds of years. Let Lao Wu take you through the secrets of ball lightning!
The mystery of ball lightning
What is ball lightning?
Although ball lightning has the word "ball", in fact, most ball lightning is oval, and some are rectangular, cube, cylinder, and even conical, spiral, etc. About the size of a football, it usually occurs in conjunction with thunderstorms. Its appearance time is as fast as two to three seconds for and up to several minutes for .

Ball lightning will also move slowly in the air. It is said that objects touched by ball lightning will be heated to hundreds of degrees in an instant. It is even said that objects that come into contact with ball lightning disappear directly. !
Witnesses of ball lightning
1. Ball lightning attacked the hospital
One day in the summer of 1962, heavy rain poured down, and continuous lightning illuminated the earth, accompanied by deafening thunder. Jiefang 106 Hospital in Jinan, Shandong Province is still very busy. After a long time, the rain gradually subsided and the operating room became stuffy and hot, so the nurse opened the window.

At this moment, a sphere that emitted a huge light suddenly floated out of the window. It slowly floated past a chandelier directly above the operating table. In an instant, the chandelier suddenly exploded! I saw the fireball flying toward the switch again. The bright lights in the entire hospital disappeared directly and were replaced by darkness. Fortunately, no one was injured in this incident.

2. Ball lightning attacked the passenger plane
On a certain day in January 1981, a Soviet passenger plane was flying over the Black Sea Over , everything was normal at first, and the Black Sea outside the window was calm. But when they passed through a dark cloud, they saw an amazing scene - A large fireball penetrated the cab, making a huge explosion, and After a few seconds, he entered the cockpit.
Ball lightning entered the interior cockpit of the aircraft.
I saw it floating up and down in the cockpit for a few seconds, and then suddenly disappeared. . The passenger plane made an emergency landing at a nearby airport. The inspection report pointed out that a huge ball lightning-like hole appeared in the metal walls of the nose and tail. Its cross section was extremely smooth, and the ball lightning cut it like tofu. Generally cut off a 10cm thick steel plate !
How is ball lightning formed?
1. Dark matter converter said
Some scientists once believed that the reason why ball lightning can make objects disappear is because ball lightning appears in the form of plasma that vibrates at high speed, and it can create extremely strong electromagnetic fields. , convert the contact material into dark matter .

However, humankind’s current understanding of dark matter is still very short, and we still don’t even know how dark matter is formed or what it is made of, so this statement still needs to be studied.
2. Evaporated silicon theory
Among the many theories about ball lightning, the evaporated silicon theory is the most recognized. They believe that ball lightning is composed of silicon. The evidence they gave is a spectrum chart. .

It can be seen that part of ball lightning is made of silicon. As for the reason for the presence of silicon in ball lightning, they gave a reasonable explanation : When lightning hits the ground, the strong current separates the oxygen in the silicon dioxide in the soil and turns it into pure silicon particles, and Due to the momentary high score, the silicon particles vaporized and finally turned into aerosol , forming ball lightning.
It is said that the genius scientist Nikola Tesla of the 20th century once solved the mystery of ball lightning. Unfortunately, it has been buried in the soil with Tesla forever. The mystery of ball lightning still needs to be solved. open.
