A Schwarzschild black hole or static black hole is a black hole that has neither electric charge nor angular momentum (non-rotating). A Schwarzschild black hole is described by the Schwarzschild metric, and cannot be distinguished from any other Schwarzschild black hole except by its mass.

A black hole cosmology (also called Schwarzschild cosmology or black hole cosmological model) is a cosmological model in which the observable universe is the interior of a black hole.
The Schwarzschild radius or the gravitational radius is a physical parameter in the Schwarzschild solution to Einstein's field equations that corresponds to the radius defining the event horizon of a Schwarzschild black hole. It is a characteristic radius associated with any quantity of mass.
A black hole with zero charge Q = 0 and no angular momentum J = 0. The exterior solution for such a black hole is known as the Schwarzschild solution (or Schwarzschild metric), and is an exact unique solution to the Einstein field equations of general relativity for the general static isotropic metric (i.e., the most general metric tensor that ...
A metric refers to an equation which describes spacetime; in particular, a Schwarzschild metric describes the gravitational field around a Schwarzschild black hole - a non-rotating, spherical black hole with no magnetic field, and where the cosmological constant is zero.
In this section we generally describe black holes and then show that the Schwarzschild spacetime where the matter has collapsed beyond \(r = 2m\). We investigate the solution for all \(r > 0\) and show that it is a black hole solution.
This radius is called the Schwarzschild radius. For a solar mass black hole, the event horizon has a radius of only 3 km. For a one billion solar mass black hole, which is about the maximum mass expected for a black hole at the center of a galaxy, the radius is 20 AU, or about the distance of Uranus from the Sun. In other words, black holes are ...
