Ok briefly observable but not anymore and never will be. And galaxies can move faster than the speed of light: https://m.phys.org/news/2015-10-galaxies-faster.html

I was going to correct that technicality on observable but was on mobile earlier.

Also you can absolutely have a theory that explains the observable universe reliably (i.e. Verifiable) but at the same time makes suggestions about the unobservable universe (for example most cosmos theories say the actual universe is bigger than the observable). We just don't have the technology or time to observe it yet.

Your link clarifies the statement. Space is expanding. Galaxies aren't actually moving FTL.

Yes I meant we can't see or go there because it's expanding / moving faster than we can get there (light).... I'm still not sure if I'm completely wrong or just misunderstood (given the downvote).
