Silly question:
Are photons traveling down into a potential (i.e. gravitational) energy well blue shifted, and ones traveling out red shifted? In other words, can a photon posses gravitational potential? If so why doesn't a derivation of the Schwarzschild radius using the concept of photon energetics yield the same expression?
given: E = hf, E = mc^2, Ep = -GMm/r
m = Ec^-2 = hf/c^2
hf = GM(hf)/(r * c^2)
1 = GM/(r * c^2)
r = GM/c^2
Rsch = 2GM/c^2
Isn't Rsch the radius of the body?
