"Implausibly Large Structure" in the Universe

  1. May 17, 2014 #1
    How much of a threat is this assembly/structure of quasars (400 billion light years long) to the homogeneity hypothesis of the universe?

    Is it being taken seriously in academis circles or are researchers shrugging it off for the moment?

    Here's the paper the Sixty Symbols video is talking about:
    "A structure in the early universe at z ~ 1.3 that exceeds the homogeneity scale of the R-W concordance cosmology"

    Looks like it hasn't been published yet.

    By the way, it's 4 billion ly, not 400.

    Well, the paper has been published, even the arXiv page says accepted for publication (Journal reference: 2013, MNRAS, 429, 2910). However, from what I understand it's not a very good one. See this paper and a more popular account on the blog of the author.

    Thanx phsopher, seems like it's nowhere near a show-stopper...
