Here are all the possible meanings and translations of the word cfa2 great wall.


  1. CfA2 Great Wall

    The Great Wall, sometimes specifically referred to as the CfA2 Great Wall, is one of the largest known super-structures in the Universe,. It is a filament of galaxies approximately 200 million light-years away and has dimensions which measure over 500 million light-years long, 300 million light-years wide and 16 million light-years thick, and includes the Hercules Superclusters, the Coma Supercluster and the Leo Cluster. It was discovered in 1989 by Margaret Geller and John Huchra based on redshift survey data from the CfA Redshift Survey. It is not known how much farther the wall extends due to the plane of the Milky Way galaxy in which Earth is located. The gas and dust from the Milky Way 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. The volume of the wall is estimated to be approximately 2.0318173e+45 km³. 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. 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.
