The distance between the central singularity and event horizon of a black hole. The length of the Schwarzschild Radius depends on the mass of the black hole. Anything inside this radius can not escape the black hole.
The radius that, according to Schwarzschild's solutions to Einstein's equations of the general theory of relativity, corresponds to the event horizon of a black hole. science : A branch of knowledge based on the laws of nature.
The distance from the center of a non-rotating black hole such that, if all the mass were compressed within that region, the escape velocity would equal the speed of light. Once a stellar remnant collapses within this radius, light cannot escape and the object is no longer visible. See event horizon.
The Schwarzschild radius is the radius of the event horizon of a black hole. This is the distance from a black hole at which nothing can escape, bot even light. Within the Schwarzschild radius, the escape velocity from the black hole is greater than the speed of light. The size of the Schwarzschild radius may be proportional to the mass of the black hole. For a typical black hole with a mass 10 times that of the Sun, the Schwarzschild radius would be roughly 18.6 miles (30 km). The Schwarzschild radius is named for the German astronomer Karl Schwarzschild, who predicted the existence of collapsed stellar bodies that cannot emit radiation, in 1916.
The size of the event horizon in a non-rotating black hole. How big is a black hole
The Schwarzschild radius (sometimes inappropriately referred to as the gravitational radiushttp://hyperphysics.phy-astr.gsu.edu/hbase/relativ/blahol.html#c2) is a characteristic radius associated with every mass. It is the radius for a given mass where, if that mass could be compressed to fit within that radius, no force could stop it from continuing to collapse into a gravitational singularity. The term is used in physics and astronomy, especially in the theory of gravitation, general relativity.
