Just saw this http://www.space.com/19220-universe-largest-structure-discovered.htmlarticle about a quasar group that's 4 Gly long. Not to speculate too much, but any thoughts on how much of an impact this could have on our current models and understanding of the formation of the universe? The article says it "challenges modern theory" but I am curious, to what extent could it change how we look at the universe? Moderators: if this becomes too speculative, I apologize, and please shut it down if that is the case. Thank you all ahead of time.
