From Wikipedia, the free encyclopedia

Kugelblitz is a compound German word, from "kugel" (ball) and "blitz" (lightning, or fire)

Meanings include:

• The German Kugelblitz tank of World War II, whose innovation was that it had a fully-rotating gun turret (hence, "circle of fire").

• The atmospheric phenomenon of ball lightning.

• kugelblitz (astrophysics) -- a concentration of light so intense that it forms an event horizon and becomes self-trapped
