Giant structure in space challenges our understanding of the universe (cosmosmagazine.com)

I wish that the article had given more information, such as the distance from earth of each of the objects in the structure(s). I'm assuming from the use of the word "structure" that they are all the same distance, but the skeptic in me wonders if they are significant different distances, thus creating only the appearance of a structur.

It ain't a Wal Mart.
