comment What happens to photons that don't interact with something?
Interesting points but you don't describe a scenario were a photon lasts "forever". If photon frequency is decreasing, what happens as the frequency approaches zero? The known universe is old, but it's not yet infinitely old. Consider the analogy that white dwarfs have been cooling for "the entire Age of the Universe". That doesn't mean they will simply last forever.

Perhaps adding a reference to the article making these claims would help clarify the question.

asking if colonization is possible in such a situation seem more on topic at Space Exploration.
