Ball lightning is an unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. In the early 2000s the Missile Defense Agency funded the development of a ball lightning weapon that would have the capacity to disable electronic devices and missiles. As of 2020, however, such a weapon does not exist. The Lanzhou researchers' paper supports the theory that ball lightning results from a ground strike that creates a reaction between oxygen and vaporized elements from the soil. The presence of glass may generate ball lightning, according to another theory published in 2012.Ball lightning is usually harmless; a glowing ball of ethereal light often seen gliding or flying through the air. In rare cases it can be dangerous. Ball lightning has been seen by 5 percent of the population of the earth. This percentage is about the same as the fraction of the population that has seen an ordinary lightning strike at close range that is, close enough to see the direct point of the lightning impact. A window glass, through which ball lightning has freely passed, was investigated. We found a cavity of 0.24 mm diameter and 2 mm diameter region of dull glass. This may be a result of small material objects passage through a melted glass. This gives evidence in favor of ball lightning models as a material body. ball lightning, also called globe lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter. It usually occurs near the ground during thunderstorms, in close association with cloud-to-ground lightning. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off. The ball eventually fades as the radiation held within the bubble starts to decay and microwaves are discharged from the sphere. The lightning balls can dramatically explode as the structure destabilizes. The theory could explain many of the strange characteristics of ball lightning. The electrode at the center of a plasma ball emits a high-frequency, high-voltage alternating electric current. This current flows through the plasma filaments to create colorful tendrils of light. It's like creating your own personal bolt of lightning from the electrode to your finger!
