What I have in mind is that it's just a local turbulence in a much larger structure, for example. It seems that we have very little data about a huge structure, so fitting any model to it at this point might give us a fairly large margin of error (especially since we extrapolate from a theory that we know that is incomplete).

What are your thoughts on this finding: http://www.caltech.edu/news/farthest-galaxy-detected-47761
