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.

∙ 10y agoThe Schwarzschild radius is the radius of a sphere such that, if all the mass of an object is compressed within that sphere, the escape speed from the surface of the sphere would equal the speed of light. An example of an object smaller than its Schwarzschild radius is a black hole.

∙ 13y agoThe number take for the "radius" is normally taken to be the radius from the center to the event horizon, since nothing inside that can be observed, and since it is a point of no return. This radius is directly proportional to the mass of the black hole. From the Wikipedia article on event horizon: "For the mass of the Sun this radius is approximately 3 kilometers and for the Earth it is about 9 millimeters. In practice, however, neither the Earth nor the Sun has the necessary mass and therefore the necessary gravitational force, to overcome electron and neutron degeneracy pressure." The last sentence means that it is unlikely for the Sun to become a black hole, since it has too little mass to become one.

If the Sun has a Schwarzschild radius why isn't a black hole?
The Schwarzschild radius is a theoretical radius a thing(here: Sun) would need to be compressed to to become a black hole.
What is the significance of the Schwarzschild radius?
Anything within the Schwarzschild radius can't escape from the black hole, even at the speed of light.Anything within the Schwarzschild radius can't escape from the black hole, even at the speed of light.Anything within the Schwarzschild radius can't escape from the black hole, even at the speed of light.Anything within the Schwarzschild radius can't escape from the black hole, even at the speed of light.
What occurs at the distance of the Schwarzschild radius from the center of a black hole?
The escape velocity reaches the speed of light at the Schwarzshild radius.
Do black holes expand or collapse?
The general tendency is for black holes to grow. If any matter falls into a black hole, its mass will increase, and therefore its Schwarzschild radius (the radius of its event horizon) will increase as well.The general tendency is for black holes to grow.

What would be the Schwarzschild radii of black holes of 1 billion solar masses?
The Schwarzschild radius is directly proportional to the mass of the black hole. It is about 2.95 km for every solar mass.

What is the schwarzschild radius of earth?
The schwarzschild radius of the Earth is about 8.7 x 10 to the negative 3m. The schwarzschild radius is the radis of a sphere that is around a non-rotating blackhole. You find the Rs, or radis, by multiplying the gravitational constant(G), the mass(M), and two. You divide this by the speed of light(c) squared.
How much is the escape speed in the schwarzschild radius?
speed of sound
What black hole property determines the schwarzschild radius of a black hole?
The black hole property that determines the Schwarzschild radius of the black hole is that it has mass but no angular momentum nor electric charge.
What of a black hole is the radius from a black hole at which the escape velocity is approximately equal to the speed of light?
It is called the Schwarzschild radius
What occurs at the distance of the Schwarzschild radius from the center of a black hole?
The escape velocity reaches the speed of light at the Schwarzshild radius.
What is the schwarzschild raduis?
The Schwarzschild radius is a concept related to black holes. Given a body it is the radius such that, if all the mass of the body were squeezed (uniformly) within that sphere, then the escape velocity at the surface of the velocity would be equal to the speed of light.
What is the Schwarzschild radius for a 200 lb man?
1.4 x 10^-23 cm

The Schwarzschild radius is directly proportional to the mass of the black hole. It is about 2.95 km for every solar mass.
How much space does a black hole take up?
Not much. The whole point of a black hole is that a lot of matter is concentrated in a fairly small space. The Schwarzschild radius of the Earth - i.e., the size into which it would have to be compressed to become a black hole - is less than 1 cm; the Sun would have to be compressed into a sphere with a radius of about 3 km. In general, the Schwarzschild radius is directly proportional to the mass. In a real black hole, the Schwarzschild radius corresponds to the event horizon - the point of no return.
