Simple definition of a black hole

WebbIt's commonly described as the result of twin 'virtual' particles that naturally emerge from the vacuum being separated by gravity. Usually they would recombine and cancel out, but in this case the split leaves one half of every pair to escape as actual radiation.

Inside the event horizon, charged stationary and rotating black holes are known to have a second spherical surface of no return, called the inner horizon.

WebbAny object whose radius is smaller than its Schwarzschild radius is called a black hole. The surface at the Schwarzschild radius acts as an event horizon in a non-rotating body (a rotating black hole operates slightly differently). Neither light nor particles can escape through this surface from the region inside, hence the name "black hole". 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 ...
