If I understand it correctly, the proper time differential for a photon in flat space is zero. That is evident if the velocity of light is equal to c, so the right hand side of the Minkowski metric is equal to zero. Therefore the left side must also be zero.
My question: Is the same true for the Schwarzschild and Freidman metrics? I think yes, but I don’t know how to prove it. Thanks for any information about that.
