    The Hercules–Corona Borealis Great Wall (HCB) [1] [5] or simply the Great Wall [6] is a galaxy filament that is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter).

    The Sloan Great Wall is between 1.8–2.7 times longer than the CfA2 Great Wall of galaxies (discovered by Margaret Geller and John Huchra of Harvard University in 1989). [2] It also contains several galactic superclusters, the largest and richest of which is named SCl 126. This is located in the highest density region of the structure. [3] [4]

    en.wikipedia.org/wiki/CfA2_Great_Wall

    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 furthest point is 550 ...

    en.wikipedia.org/wiki/BOSS_Great_Wall

    The BOSS Great Wall is one of the largest superstructures in the observable universe, [2] though there are even larger structures known. This figure shows the superclusters of the BOSS Great Wall, on Cartesian coordinates. The large complex has a mean redshift of z ~ 0.47 (z times Hubble length ≈ 6.8 billion light years). [1]
