I noticed that the Schwarzschild Radius Formula and the Escape Velocity Formula are actually identical. The Schwarzschild Radius is supposed to be one of the great equations generated from Relativity, while the Escape Velocity is something that was generated just using Newtonian gravity. All you need to do is plug in the speed of light as your escape velocity and you get the Schwarzschild Formula. My question is, historically speaking was Schwarzschild actually derived from Relativity or not?
Schwarzschild Radius:
r = (2 G M)/c^2 |
r | event horizon radius
M | mass
G | Newtonian gravitational constant (≈ 6.674×10^-11 m^3/(kg s^2))
c | speed of light (≈ 2.998×10^8 m/s)
Escape Velocity:
v = sqrt((2 G m)/r) |
v | speed
m | mass
r | radius
G | Newtonian gravitational constant (≈ 6.674×10^-11 m^3/(kg s^2))
