AI Thread Summary
The discussion centers on a newly identified structure of quasars measuring 4 billion light years, which raises questions about the homogeneity hypothesis of the universe. While the structure has been accepted for publication, its significance is debated, with some researchers viewing it as not a major threat to established cosmological models. The paper has been critiqued for its quality, suggesting that it may not have a substantial impact on current understanding. Overall, the academic community appears to be cautious rather than alarmed regarding this finding. The implications of this structure on cosmology remain under scrutiny, but it is not considered a definitive challenge at this time.

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:
http://arxiv.org/abs/1211.6256
"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...IH
 

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo".'

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...

Thread 'Big Bang and Infinite Universe'

Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
