Schwarzschild Radius - Formula For The Schwarzschild Radius

Formula For The Schwarzschild Radius

The Schwarzschild radius is proportional to the mass with a proportionality constant involving the gravitational constant and the speed of light:

where:

is the Schwarzschild radius;
is the gravitational constant;
is the mass of the object;
is the speed of light in vacuum.

The proportionality constant, 2G/c2, is approximately 1.48×10−27 m/kg, or 2.95 km/solar mass.

An object of any density can be large enough to fall within its own Schwarzschild radius,

where:

is the volume of the object;
is its density.

Famous quotes containing the words formula for and/or formula:

    In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.
    Alicia F. Lieberman (20th century)

    Hidden away amongst Aschenbach’s writing was a passage directly asserting that nearly all the great things that exist owe their existence to a defiant despite: it is despite grief and anguish, despite poverty, loneliness, bodily weakness, vice and passion and a thousand inhibitions, that they have come into being at all. But this was more than an observation, it was an experience, it was positively the formula of his life and his fame, the key to his work.
    Thomas Mann (18751955)
