Great article in the September issue! It's amazing that as astronomers develop techniques to see at larger and larger scales-- they see new structures --- so, the filamentary structure now seen as the largest scale may not be the largest. I can imagine that if only we could see a much larger scale, that filamentary structure may be only the beginning of the tapestry of the universe. But, I realize that it may be a very long time before we can see a much larger scale, if ever because we are limited to "the observable universe". But, even within that scale, at greater distances, does the filamentary pattern (back in time) appear much different than closer?
Also, I can imagine that dark matter has an extremely complex structure and once we can find ways to "see" it better- that it will offer new powers to mankind. Since dark matter and dark energy make up most of the universe- it must be loaded with information which future generations will mine.
