The cluster is predicted to be one of the largest in today’ terms, and must have formed very early, full of old galaxies. How likely is the rapid formation of such a large structure using popular condensation models?
Answer to your question: I don’t know, but I would not be surprised if big bang theorists have to push their galaxy formation models to their limits to get such a massive grouping of galaxies to form at this early period. Such findings do not pose a problem for subquantum kinetics.

And now (March, 2011) a supercluster similar in mass to the Virgo Cluster has been discovered to have fully formed only 3 billion years after the Big Bang. The surprising admission is that both the cluster structure and the galaxies therein do not appear young.
April 2011: Another massive cluster 7.5 billion light years distant and 1000 times larger than the Milky Way galaxy, is the most massive cluster known.
May 2011: An unexpectedly massive quasar now discovered only 770 million years after the big bang. Current models don’t explain how it could have grown so big so fast.
