> those photons hit infinity

What does that mean "hit infinity"? I would think that could only happen after an infinite amount of time, in other words never.

It is only from the reference frame of some physical observer inside the universe that it takes time for them to reach infinity.

From the reference frame of a photon, not only does it instantly arrive at infinity, but infinity and its original position one in the same since length is contracted to zero.

So photons are at infinity already?
Yes, it can be looked at that way or that time & distance do not exist for photons.
