如何计算Schwarzschild Radius
learn.whatIsHeading
Schwarzchild radius is event horizon size of non-rotating black hole. Objects inside cannot escape, even light.
公式
Apply r_s = 2GM/c²
分步指南
- 1Input mass (solar masses or kg)
- 2Apply r_s = 2GM/c²
- 3Results show black hole horizon size
例题解析
输入
M = 10 solar masses
结果
r_s ≈ 30 km, density ≈10¹¹ kg/m³
Stellar-mass black hole
常见错误注意事项
- ✕Assuming black holes are absolute sinks (Hawking radiation evaporates)
- ✕Neglecting spin (rotating black holes larger)
常见问题
What happens at event horizon?
Tidal forces increase dramatically; approaching observer experiences infinite time dilation.
