From a photon point of view, it never travel. For it, now is all the
time.

Debatable. Let's assume that a photon starts at (x,t) = (0,0),
from the still observer's point of view. Since we can't quite use the
Lorentz we need to get creative regarding limits, but we do know
that

x' = (x-vt)/sqrt(1-v^2/c^2)

Why (x-vt) and not (x+vt), explain

He will explain and you will continue to pretend you don't understand.
And then he will explain again and you will continue to pretend you
don't understand.
Bet?
