Photons do not experience space or time. It reaches its destination 13 billion light years away or two inches away at the same exact moment it departs. Let that cook your noodle for a minute or two.

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.
