Kugelblitz (astrophysics)
A kugelblitz (German: [ˈkuːɡl̩ˌblɪt͡s] ) (English: ball lightning) is a theoretical astrophysical object predicted by general relativity. It is a concentration of heat, light, or radiation so intense that its energy forms an event horizon and becomes self-trapped. In other words, if enough radiation is aimed into a region of space, the concentration of energy can warp spacetime so much that it creates a black hole. This would be a black hole the original mass–energy of which was in the form of radiant energy rather than matter; however, there is currently no uniformly accepted method of distinguishing black holes by origin. (See the no-hair theorem.) John Archibald Wheeler's 1955 Physical Review paper entitled "Geons" refers to the kugelblitz phenomenon and explores the idea of creating such particles (or toy models of particles) from spacetime curvature. This paper coined the term kugelblitz. The formation of a kugelblitz may be impossible due to dissipative quantum effects like vacuum...
