Measurement aside, instantaneous speed is still something.
Quote:Also, I think your mixing the 'inertial' in inertial reference frame with actual inertia. Inertial reference frame means it is not accelerating. Plus, the photon has inertia since it has momentum.Okay, I retract the comments about intertia.
