OK, say I'm a photon. I'm moving at the speed of light. For me, clocks do not move. I go from A to B in zero time, at least zero photon time. That's pretty fast. Actually that's infinitely fast.
And what do I care about your stinkin' "phase velocity"? I'm a particle. I just don't have any mass. You can't hold that against me.
Oh, you can't event decide if you are a wave or a particle. Besides, I bet you are white light. Don't think that wouldn't be held against you, you, you massless photonic phasist!
I say you're a wave, and I intend to measure your phase velocity. I'm not wrong.
