Schwarzschild radius
In astronomy, a black hole's Schwarzschild radius is a radius length of influence of the black hole's event horizon.
The equation for the Schwarzschild radius is
- <math>R_{sch} = \frac{2GM}{c^2}</math>
where
- Rsch is the Schwarzschild radius,
- <math>G</math> is the gravitational constant
- 6.67 10–11 N m2 / kg2
- M is the mass of the black hole
- <math>c^2</math> is the speed of light squared
- (299,792,548 m/s)² = 8.98755 × 1016 m²/s²
