Beyond the Event Horizon
According to the widely accepted theory of black holes, based on Einstein’s relativity theory, black holes, including their supermassive variants, form when a star with a mass approximately great than 20 suns, collapses onto itself after running out of energy to support itself. The resulting dense concentration of matter has gravity so strong that it accretes everything that comes within its gravitational sphere, growing in mass all the time. Since everything includes light, a black hole is not directly visible, earning it its name. The concept of event horizons, while accepted by a large number of people, has not yet been proven, however.
