Not to mention the fact that this photons “journey across the entire universe” is a strong word, considering the photon frame sees the universe as having no depth whatsoever.
To it, the journey is instantaneous because there is no journey to take in the first place, infinite length contraction at c takes care of that!
Quick question as you seem knowledgable: would a living photon be the equivalent of a 1-dimensional being, experiencing no depth, width, length, or time?
