This universe is nothing but a cluster of magnificent and phenomenal objects. The gargantuan structures in the universe are what that makes it fascinatingly thought provoking. Huge LQG is one such ginormous megastructure. It is the largest quasar group, discovered till date. Measuring about 4 billion light years across, it is apparently the dwelling spot of around 73 quasars. When discovered, it was thought to be the largest possible structure in this whole wide universe, but later on, lost this delegation to HCB great wall. Through the sloan digital sky survey (used in multi-imaging and redshift of the sky), it was discovered in the environs of constellation LEO.
Huge LQG is expected to be 1.24 gigaparsec long, 640 megaparsec wide and 370 megaparsec high and around 9 billion light years away from Earth. This analysis proposed that quasars in the cluster appear closer together than predicted for random positions. Apart from its record breaking size, this massive structure may end up shedding light in the evolution of galaxies and may provide some opportunity to sneak into the birth of this universe.
When it comes to cosmological principle, it’s rare to find this sort of megastructure obeying the cosmological principle which states that this universe is homogenous. To define this homogeneity, an upper limit of about 260/h megaparsec has been set, but this structure is around the twice of this limit, clearly defying the cosmological principle and ultimately spurning our knowledge of this universe in a nick of time.
Since the discovery was more of a shock than a surprise as it defied the cosmological principle, it has been subjected to zillions of disputes, where some scientists refused to believe its existence, terming it as a pseudo structure. But clowes (the founder of clowes-Campusano LQG), winded up this dispute with the use of mg ll absorbers (ionized magnesium gas, used to examine distant galaxies). Further the measurement of the polarization of the quasars in huge LQG shown a noteworthy correlation with polarization vectors, hence validating its existence.
