Scientific Explanation
Ball lightning is a natural phenomenon, or debatably, a pseudoscientific theory. It is sometimes associated with thunderstorms. It takes the form of a long-lived, glowing, floating object, as opposed to the short-lived arcing between two points commonly associated with lightning. An early attempt to explain ball lightning was recorded by Nikola Tesla on March 5, 1904.
There may, however, be special forms of plasma for which the above arguments do not fully apply. In particular, a plasma may be composed of negative and positive ions, rather than electrons and positive ions. In that case, the recombination may be rather slow even at ambient temperature. One such theory involves positively charged hydrogen and negatively charged nitrites (NO2–) and nitrates (NO3–). In that theory, the role of the ions as seeds for the condensation of water droplets plays an important role.
Ball lightning has also been seen to appear inside an aircraft, which has a metallic skin. Since the electric field cannot penetrate metal, there is a possibility ball lightning could be some form of induction phenomenon.

Famous quotes containing the words scientific and/or explanation:
“The truth is that our race survived ignorance; it is our scientific genius that will do us in.”
—Stephen Vizinczey (b. 1933)
“Herein is the explanation of the analogies, which exist in all the arts. They are the re-appearance of one mind, working in many materials to many temporary ends. Raphael paints wisdom, Handel sings it, Phidias carves it, Shakspeare writes it, Wren builds it, Columbus sails it, Luther preaches it, Washington arms it, Watt mechanizes it. Painting was called “silent poetry,” and poetry “speaking painting.” The laws of each art are convertible into the laws of every other.”
—Ralph Waldo Emerson (1803–1882)
