Astronomers have discovered what they call the greatest known structure in the universe. Called “quipu” after an Incan measurement system, the superstructure includes an amazing 1.3 billion light years, which is more than 13,000 times the length of the Milky Way, according to a report in Live science.
The current competition for the largest structure in the universe is the Hercules-Corona Borealis Great Wall that is 10 billion light years of the earth and spans 10 billion light years, but its existence remains disputed.
While they are staring through the data, the researchers discovered Quipu and four more gigantic structures. Together these five super clusters contain 45 percent of the galaxy clusters, 30 percent of the galaxies and 25 percent of the business in the observable universe, according to the study published in the PrePrint website Arxiv who still needs to be written.
“Quipu is actually a prominent structure that is easily noticeable in a sky folder of clusters in the Target Redshift Range, without the help of a detection method,” the team wrote.
Superclusters are large collections of Melkweg clusters, groups and individual galaxies that are usually not bound to each other. Our Galaxy Milky Way is on the outer edges of the Laniakea supercluster.
According to the study, Quipu is responsible for a “large part of the gravity that causes the special movement of the local group with regard to the cosmic microwave background (CMB) frame”. However, more information is needed to identify the effects of such a structure in the neighborhood.
“For a precise determination of cosmological parameters, we must understand the effects of the local large -scale structure of the universe on the measurements,” the authors wrote …

'Transient configurations'
The scientists added that although the superstructure was at the moment enormous, it would quickly collapse and form independent units.
“In future cosmic evolution, these super structures will certainly separate in various collapsing units,” the study emphasized.
“So they are temporary configurations. But currently they are special physical entities with characteristic properties and special cosmic environments that deserve special attention.”
According to the researchers, studying an object can be as massive as Quipu our understanding of how galaxies evolve and improve our cosmological models.
