Schwarzchild radius is event horizon size of non-rotating black hole. Objects inside cannot escape, even light.
Formel
Apply r_s = 2GM/c²

Input
M = 10 solar masses
Resultat
r_s ≈ 30 km, density ≈10¹¹ kg/m³
Stellar-mass black hole
Almindelige fejl at undgå
- ✕Assuming black holes are absolute sinks (Hawking radiation evaporates)
- ✕Neglecting spin (rotating black holes larger)
Ofte stillede spørgsmål
What happens at event horizon?
Tidal forces increase dramatically; approaching observer experiences infinite time dilation.
