The Hercules-Corona Borealis Great Wall is a huge superstructure of galaxies that measures more than 10 billion light years across[1][2]. It was the largest and the most massive structure known in the observable universe.
This huge galactic filament was discovered on November 2013 by a mapping of gamma ray bursts that occurs in the distant universe[3][4]. The filament has the mass of approximately 5 quintillion solar masses[citation needed].
Homogeneity problem
According to a data by some astronomers, such structures that exceed 1.2 billion light years in length may exceed the tips of the scales of the cosmological principle, which states that, the random fluctuations in quantities such as the matter density between different regions of the universe are small. Different data approves this and found out that scales exceeding this limit may defy the said principle.
The Sloan Great Wall, discovered in 2003, is 1.37 billion light years across, and is marginally larger than the scale.
The Huge-LQG(Huge Large Quasar Group), discovered in 2013, is 4 billion light years across. However, long range correlations provide evidences of the impossibility of this structure.
The Hercules-Coma Borealis Great Wall, is more than 8 times larger than the scale, and so greatly exceeds the homogenity scale.
