What if the hypothetical existence of one is verifiable?
If it's verifiable, it isn't hypothetical, is it?
The hypothesis can be verifiable.
In which case, we're talking about the notability of a hypothesis, not of a galaxy or an ETI. The hypothesis could have an article, but would a galaxy that's only claim to notability is being mentioned in this hypothesis warrant anything more than a redirect to the ariticle on the hypothesis?
I really don't see a difference between an article on a hypothesis of a galaxy and an article on the galaxy itself. Again, take [[Phaeton (hypothetical planet)]]. We don't call that [[hypothesis about a planet between Mars and Jupiter]].

We estimate there are hundreds of billions. But only 3000 are "visible". I wonder what "visible" means, and I wonder how many are "observable".
I think that 3000 is how many there were in the tiny bit of sky they looked at. I think it's a reference to the Hubble deep field (http://en.wikipedia.org/wiki/Hubble_deep_field). The total number of galaxies in the observable universe is in the billions, certainly.
My bad. I made a poor use of terminology (I didn't really mean "within the observable universe"), and a terribly poor estimate of numbers anyway. You win, I lose.
