In theoretical physics, a kugelblitz is a concentration of heat, light or radiation so intense that its energy forms an event horizon and becomes self-trapped: according to general relativity and the equivalence of mass and energy, if enough radiation is aimed into a region, the concentration of energy can warp spacetime enough for the region to become a black hole, although this would be a black hole whose original mass–energy had been in the form of radiant energy rather than matter.[1] In simpler terms, a kugelblitz is a black hole formed from radiation as opposed to matter.[according to whom?]
John Archibald Wheeler's 1955 Physical Review paper entitled "geons" refers to the kugelblitz phenomena and explores the idea of creating such particles (or toy models of particles) from spacetime curvature.[2] (It also introduces the idea that lines of electric charge trapped in a wormhole throat might be used to model the properties of a charged particle-pair.[2][relevant?]) It is perhaps the best-known reference to the kugelblitz idea in English.[according to whom?]
A man-made kugelblitz has been described as conceivable through use of a gamma-ray laser one billion-times stronger than those currently available,[citation needed] which would have to produce a pulse with a duration one 100-billionth of that of gamma-ray lasers currently available.[citation needed][when?] The energy of a single pulse of such a laser would equate to the energy produced by the sun in 1/10 of a second.[citation needed] A kugelblitz of this size would last five years,[citation needed] and a micro Dyson sphere could be constructed around it to harness the energy produced by the Hawking radiation.[according to whom?]
The kugelblitz phenomena has been considered a possible basis for intersteller engines (drives) for future black hole starships.[3][4][non-primary source needed]
