(bold mine. extra exclamation points, all yours.)
Well, there's your problem. The part about mass. Photons have "no rest mass", remember? They don't exist unless they're moving at lightspeed. The only time they even "slow down" (sort of) is when they get absorbed into a particle with mass-- which means they're not photons any more. they've been converted into another form of energy. If they're re-radiated, they become photons again, and therefore must move at lightspeed. Their "mass" never changes, only their energy.
