A kugelblitz (German: [ˈkuːɡl̩ˌblɪt͡s] ) 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 whose original mass–energy was in the form of radiant energy rather than matter, [1] however, there is currently no uniformly accepted method of distinguishing black holes by origin.
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. [2]
A preprint published in early 2024 argues that the formation of a kugelblitz is impossible due to dissipative quantum effects like vacuum polarization, which prevent sufficient energy buildup to create an event horizon. [3] The study concludes that such a phenomenon cannot occur in any realistic scenario within our universe.
The kugelblitz phenomenon has been considered a possible basis for interstellar engines (drives) for future black hole starships. [4] [5][ non-primary source needed]
- A kugelblitz is a major plot point in the third season of the American superhero television series The Umbrella Academy.
- A kugelblitz is the home of a major faction in Frederik Pohl's " Gateway" novels.
