The Hercules-Corona Borealis Great Wall (Her-CrB GW) is a Galaxy Filament discovered in 2013 in the investigation of a Gamma-Ray Burst. It has a Redshift in the range of 1.6-2.1, i.e., 10 billion light-years distant, and is 10 billion light-years long, 7.2 billion light-years wide and 900 million light-years thick. It is a billion light-years away and is 1.3 billion light-years across.
It displaced the Sloan Great Wall as the largest known structure in the universe. Its size presents scientific questions that promise to influence theories and research.
