The term "Great" has been added to distinguish it as an even larger type compared to standard galaxy walls.
The CfA2 Great Wall has the maximum dimensions of either 500 million or 750 million light years depending on the figure and the reference used.[citation needed] It is 200 million light years in width and about 16 million light years in thickness. Its nearest point is about 300 million light years from Earth, while its farthest point is 550 million light years away. It consists of three massive galaxy superclusters: Hercules, Coma, and Leo.
It is not known how much farther the wall extends due to the light absorption in the plane of the Milky Waygalaxy in which Earth is located. The gas and dust from the Milky Way (known as the Zone of Avoidance) obscure the view of astronomers and have so far made it impossible to determine if the wall ends or continues on further than they can currently observe.
In the standard model of the evolution of the universe, such structures as the Great Wall form along and follow web-like strings of dark matter.[2] It is thought that this dark matter dictates the structure of the Universe on the grandest of scales. Dark matter gravitationally attracts baryonic matter, and it is this "normal" matter that astronomers see forming long, thin walls of super-galactic clusters.
