why, it won't make it through peer review. high frequency light arrives first because it interacts less with matter. remember, c is only constant in a true vacuum. the speed of light varies as it travels through matter (refraction). there is a lot of "stuff" to interact with between us and a galaxy 14 billion light years away i wonder if the energy of empty space (yes, empty space has energy) plays a role in slowly dissipating the energy from light.
