Is this askscience FAQ answer about "what is the universe expanding into" incorrect? It's saying that the distance between two "otherwise stationary" points will continue to increase. And that our "cosmic ruler" grows over time. To a non-cosmologist like me that sounds like the expert is saying space itself is expanding
