Ball lightning is an unexplained atmospheric electrical phenomenon. The term refers to reports of luminous, usually spherical objects which vary from pea-sized to several meters in diameter. It is usually associated with thunderstorms, but lasts considerably longer than the split-second flash of a lightning bolt. Many of the early reports say that the ball eventually explodes, sometimes with fatal consequences, leaving behind the odor of sulfur.
Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to any naturally occurring phenomenon. Scientific data on natural ball lightning are scarce owing to its infrequency and unpredictability. The presumption of its existence is based on reported public sightings, and has therefore produced somewhat inconsistent findings. Given inconsistencies and the lack of reliable data, the true nature of ball lightning is still unknown.

Famous quotes containing the words ball and/or lightning:
“Life ... is not simply a series of exciting new ventures. The future is not always a whole new ball game. There tends to be unfinished business. One trails all sorts of things around with one, things that simply won’t be got rid of.”
—Anita Brookner (b. 1928)
“God from the mount of Sinai, whose grey top
Shall tremble, he descending, will himself
In thunder lightning and loud trumpets’ sound
Ordain them laws; part such as appertain
To civil justice, part religious rites
Of sacrifice, informing them, by types
And shadows, of that destined seed to bruise
The serpent, by what means he shall achieve
Mankind’s deliverance.”
—John Milton (1608–1674)
