In the first post, Chronos writes:

Chronos said:In a universe of this size there are bound to be anomalies. How large is large enough to be improbable is a statistical exercise.

Is this overly dismissive? That "statistical exercise" has been done by Yadav et al., and it is precisely on the basis of that calculation that Clowes has suggested the discovery is inconsistent with the cosmological principle. Granted, Yadav's paper doesn't itself seem to have gotten much attention (Google Scholar gives nine citations) so is Clowes wrong to suggest that the Huge-LQG is a problem for homogeneous models of the universe? If it is a problem for homogeneity, how much of concordance cosmology would need to be rethought (i.e. can Lambda-CDM and various results about inflation, etc., be easily retooled for an inhomogeneous metric)? Or can this be accounted for within the FLRW model, contrary to my reading of Yadav et al.?

I'd be very grateful if some cosmologists could weigh in on these questions.
