Reply to comment by Civil_Willingness298 in Where do photons go if they've been emitted but are destined to never be absorbed, and would these photons traveling ad infinitum define the edge of the universe (even if space itself were still larger)? by mysteryofthefieryeye
I'm sorry, that's incorrect, and no noodle has been cooked. From the point of view of the photon, sure, you are right. But the physical packet of information still travels at the speed of light, and even then that speed can be altered by an intervening atmosphere or interstellar medium. By your logic, the starlight I see outside is both here and just leaving the star simultaneously, which is 100% inaccurate.

I know light doesn't experience time. From the photon's vantage, you are right. But in physical space, it still takes time for the photon to reach a destination. Downvote me all you want but your original comment is plainly wrong.

It is the extreme end of time dilation. Well accepted physics for a century.
