Yes, wonderful. But what the heck is it? I see no mention of what the wall actually is or what it's made of.

• Galaxies. Just like any other large-scale cosmic structure. Nickptar 01:45, 30 Mar 2005 (UTC)

Cosmic filaments should be mentioned here!

• I think you mean galaxy filament

[edit] Dark Matter Speculation

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.

[edit] Discrepancies

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?
