Schwarzchild radius is event horizon size of non-rotating black hole. Objects inside cannot escape, even light.

Fórmula

Apply r_s = 2GM/c²

Guía paso a paso

  1. 1Input mass (solar masses or kg)
  2. 2Apply r_s = 2GM/c²
  3. 3Results show black hole horizon size

Ejemplos resueltos

Entrada
M = 10 solar masses
Resultado
r_s ≈ 30 km, density ≈10¹¹ kg/m³
Stellar-mass black hole

Errores comunes a evitar

  • Assuming black holes are absolute sinks (Hawking radiation evaporates)
  • Neglecting spin (rotating black holes larger)

Preguntas frecuentes

What happens at event horizon?

Tidal forces increase dramatically; approaching observer experiences infinite time dilation.
