WebbKugelblitz (astrophysics) A kugelblitz 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 ... WebbIn astrophysics, spaghettification (sometimes referred to as the noodle effect) is the vertical stretching and horizontal compression of objects into long thin shapes (rather like spaghetti) in a very strong, non-homogeneous gravitational field.It is caused by extreme tidal forces.In the most extreme cases, near a black hole, the stretching and … Webb9 apr. 2024 · The scientific definition of a black hole is fairly simple.
