Basically that light travels at a definite and finite speed and at that speed time ceases to be.
Time doesn't cease to be. It just stops progressing relative to our frame of reference. In its own frame of reference it goes merrily on the same as normal.
If you actually were to be acclerated from our frame of reference all the way to the frame of reference of the photon, you personally would never detect any change or transition.

From the perspective of the photons, they already did.
Put that in your pipe and smoke it.
Negative,
If you traveled at the speed of light toward an object and the space between you and that object was expanding faster than the speed of light, your destination would be reached in an instant from your perspective. However your ultimate destination would not be that object you aimed for because that initial desired destination is simply out of your reach.
You seem to implie there is in theory some some absolute marker that could denote your desired initial destination. There isn't.
This is a conceptual error.

But that defies all logic! >_<
No. From the perspective of the photon it will never reach us either.
