Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "The Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion ...
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).

This is a list of largest galaxies known, sorted by order of increasing major axis diameters. The unit of measurement used is the light-year (approximately 9.46 × 10 12 kilometers). Overview
At its discovery, it was identified as the largest and the most massive known structure in the observable universe, [1] [2] [3] though it has been superseded by the Hercules–Corona Borealis Great Wall at 10 billion light-years. [4] There are also issues about its structure (see Dispute section below).
Given the age of the universe and the composition of available matter, there is simply not enough time to grow black holes larger than this mass. The limit is only 5 × 10 10 M ☉ for black holes with typical properties, but can reach 2.7 × 10 11 M ☉ at maximal prograde spin (a = 1). [a] SDSS J123132.37+013814.1: 1.12 +0.28 −0.23 × 10 11 ...
That means there’s something in the underlying physics of our universe that remains a mystery. The Hubble tension is one of the most hotly debated discrepancies in all of astronomy.
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
