Kugelblitz (astrophysics) In theoretical physics, a kugelblitz (German: "ball lightning", not to be confused with ball lightning) is a concentration of light so intense that it forms an event horizon and becomes self-trapped: according to general relativity, 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).
In simpler terms, a kugelblitz is a black hole formed from energy as opposed to mass. According to Einstein's general theory of relativity, once an event horizon has formed, the type of mass-energy that created it no longer matters. A kugelblitz is so hot it surpasses the Planck temperature, the temperature of the universe 5.4×10−44 seconds after The Big Bang. A kugelblitz is an important plot element in Frederik Pohl's novel Heechee Rendezvous. Newtonian Dynamics. Main Page - partsregistry.org. How Hot. Right Angle Circuitry. Mr. Tompkins.

The hands of the big clock on the tower down the street were pointing almost to noon and the streets were nearly empty. A single cyclist was coming slowly down the street and, as he approached, Mr Tompkins' eyes opened wide with astonishment. Mr Tompkins did not notice that he gained much in speed, but, as the result of his effort, he flattened still more and went down the street looking exactly like a picture cut out of cardboard. Then, Mr Tompkins felt very proud because he could understand what was happening to the cyclist-- it was simply the contraction of moving bodies about which he had just learned.
"Evidently nature's speed limit is lower here," he concluded, "that is why the bobby on the corner looks so lazy, he need not watch for speeders. " [It has much more power than a bicycle, so the dilation is greater to observers.] "By Jove! “Speed limit?” “Well ! “Oh! SkyServer Famous Places.
