That is the premise of the article. It is bizarre in relation to our models of the universe. We don't know if it is unusual in relation to the universe itself. As the article states: >Clearly, the theoretical models are wrong, or at least (and more likely) incomplete. Obviously, there’s more to learn about galaxies that exist at the edge of the observable Universe. I am reminded of that tale about how "Eureka!" is not exclamation of good science but instead "That's odd.". This article is saying "That's odd." in a way that signals we are on the verge of new scientific discovery.
