Yes, wonderful. But what the heck is it? I see no mention of what the wall actually is or what it's made of.
Cosmic filaments should be mentioned here!
I removed the phrasing that suggested the existence of dark matter was hotly debated. From the article on Dark Matter,
Together with Rubin's findings for spiral galaxies and Zwicky's work on galaxy clusters, the observational evidence for dark matter has been collecting over the decades to the point that today most astrophysicists accept its existence as a matter of course. As a unifying concept, it is one of the dominant features considered in the analysis of structures on the order of galactic scales and larger.
It is perfectly acceptable to talk about dark matter as if it is accepted by the scientific community in general, because it is. True, there are possible other plausible explanations for the observations which are taken as evidence for dark matter, but the idea of dark matter is nonetheless well accepted. The primary focus of debate is on the nature of dark matter.

This article states that the CfA2 Great Wall is 500 million light years long, but the article on the Sloan Great Wall states that the SGW is 1.37 billion light years long and 80% longer than the CfA2 Great Wall. This article also says the SGW was discovered in 2004, whereas the SGW article states that the SGW was discovered in October 2003. Which article is right?

I just moved the text with the mention of the Wall's volume from the see also section to the main body (and improved the formatting). When trying to convert the volume to cubic parsecs, I found that that volume is equal to Roughly 7% of the volume of a small dwarf galaxy. I'm by no means an expert in the field of cosmic megastructures, but doesn't that seem a bit... small for something referred to as a great wall? Julesmazur ( talk) 19:49, 1 June 2013 (UTC)
Your statement "...and it is this "normal" matter that astronomers see forming long, thin walls of super-galactic clusters." as it stands, is patently wrong. What astronomers "see" are photons (gauge bosons) not baryonic matter (or reflections of light thereon). To say that astronomers "see" these galactic strings or super-galactic clusters as "normal" matter is misleading to say the least.
