Schwarzschild Radius
The Schwarzschild radius is the radius of the event horizon surrounding a non-rotating black hole. Any object with a physical radius smaller than its Schwarzschild radius will be a black hole.
Schwarzschild radius :
Schwarzschild radius is the radius below which the gravitational attraction between the particles of a body must cause it to undergo irreversible gravitational collapse.

It should be noted that the Schwarzschild radius only applies to spherical objects, and is a consequence of his description of the space-time geometry around any spherical object, not necessarly a black hole.
SCHWARZSCHILD RADIUS
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.
Schwarzschild radius The distance from the center of an object such that, if all the mass compressed within that region, the escape velocity would equal the speed of light.
Schwarzschild Radius
(a) The critical radius, according to the general theory of relativity, at which a massive body becomes a black hole, i.e., at which light is unable to escape to infinity. Rs = 2GM / c2; Rs for Sun, 2.5 km; Rs for Earth, 0.

Schwarzschild radius the distance from a black hole's center at which the escape velocity equals the speed of light (same as the event horizon). season approximately three-month period bounded by an equinox and a solstice.

Schwarzschild radius - (n.)
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.
Schwarzschild radius 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.
Schwarzschild Radius - the "radius" of a black hole. Not really, it is the distance you have to be from a black hole to escape if you are travelling at the speed of light.
Schwarzschild Radius: The radius of the event horizon surrounding a nonrotating black hole. Its size is given by Rs = 2GM / c2. For a one solar mass star this is about 3 kilometers.
The Schwarzschild radius can be calculated using the equation for escape speed.
vesc = (2GM/R)1/2
For photons, or objects with no mass, we can substitute c (the speed of light) for Vesc and find the Schwarzschild radius, R, to be
R = 2GM/c2 ...
The Schwarzschild radius is given by
r_{rm S} = {2,Gm over c^2}
where G is the gravitational constant, m is the mass of the object, and c is the speed of light.
Now, the Schwarzschild radius of a body of mass m is given by lS = 2Gm / c2.
Before the free falling observer passes the Schwarzschild radius, a call for help signal can in principle reach the distant Earth or a spaceship.
A black hole is a massive object (or region) in space that is so dense that within a certain radius (the Schwarzschild radius, which determines the event horizon), its gravitational field does not let anything escape from it, not even light.
This is because the Schwarzschild radius is directly proportional to mass, while density is inversely proportional to the volume.
This particular radius, R, is called the 'Schwarzschild radius' in honour of the German astronomer who first derived it from Einstein's theory of gravity.

This implies that the hard X-rays come from a VERY small region; a black hole of 108 solar masses has Schwarzschild radius of 980 light-seconds. Beaming of relativistically-moving blobs might relax this problem somewhat.
It is believed that if the stellar mass is high enough, the neutrons themselves will be crushed and the star will collapse until its radius is smaller than the Schwarzschild radius and it becomes a black hole.
R S = 2 G M / c 2 where M is the mass of the black hole, G is the gravitational constant and c is the speed of light. The Schwarzschild radius of a solar mass black hole is about 3 km.
Such objects for a while were called frozen stars since the collapse would be observed to rapidly slow down and become heavily reddened near the Schwarzschild radius.
The distance from the "center" of a black hole to its "edge" (called an event horizon). If the Earth became a black hole, all of its mass would be squeezed into a sphere with a Schwarzschild radius of 0.03 cm, about the size of a bacterium.
The place beyond which no radiation can escape is called the event horizon, and its radius is called the Schwarzschild radius after the German astronomer Karl Schwarzschild, ...
Astronomer Karl Schwarzschild showed that the radius of the event horizon in kilometers is 3 times its mass expressed in units of solar masses; this radius is called the Schwarzschild radius.
Furthermore, nothing can prevent a particle from hitting the singularity in a very short amount of proper time once it has entered the event horizon. For a nonrotating black hole, the horizon is located at the Schwarzschild radius.
As it passed through the horizon, both the object and its energy would disappea-a hypothetical phenomenon referred to as advection-dominated accretion flow (ADAF). Once a body has contracted within its Schwarzschild radius, ...
