So two adjacent galaxies may "not be moving" relative to one another but the distance between them could be increasing at a rate greater than the speed of light. A quasi-pseudo-paradox

Whether this is in jest or serious ... I still don't get what possible meaning of "observable" people are using when they say something 46Gly away is observable.
Isn't that like me sitting on my deck chair in Sydney and saying I can observe cars in Melbourne, because auntie Lizzy visited two weeks ago and parked hers in my garage and I have a theory that predicts this car now to be in Melbourne?
