For a bit of context (from a similar but different question), here is a post I wrote comparing the balloon analogy to the explosion in space: Do we know the exact spot where big bang took place?

comment How do I soundproof a Meade ETX-90 telescope?
Oh, yes. Gear talk is definitely on topic here. It is the #1 thing listed as on topic"Setting up, using and maintaining your astronomy related equipment." Gear talk and trouble-shooting is often a big part of any half-way decent site on observational astronomy. Let's not lose sight of that. Trying to close this as "opinion-based" is ludicrous. It's one of those applied, day-to-day problems I wish there was more of on this site.

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.

comment Could we actually freeze a star?
Perhaps adding a reference to the article making these claims would help clarify the question.

comment What is the danger for Ceres of collision with other asteroids?
asking if colonization is possible in such a situation seem more on topic at Space Exploration.
