## Schwarzschild Radius
The Schwarzschild radius defines the event horizon of a non-rotating black hole.
### Formula
**r_s = 2 G M / c²**
For a solar-mass black hole, r_s ≈ 2.95 km. The radius scales linearly with mass.

计算示例
A 1-solar-mass black hole (M = 1.989e30 kg).
- r_s = 2 G M / c²
- 2 × 6.674e-11 × 1.989e30 = 2.654e20
- c² = (2.998e8)² = 8.988e16
- r_s = 2.654e20 / 8.988e16 ≈ 2953 m ≈ 2.95 km
