Astronomers Identify Quipu, the Largest Known Structure in the Universe

The colossal cosmic web spans 1.4 billion light-years and challenges fundamental assumptions about the universe's structure.

Quipu, a newly discovered superstructure, is composed of nearly 70 galactic superclusters and stretches 1.4 billion light-years across.
The structure's mass is estimated at 200 quadrillion times that of the sun, equivalent to 130,000 Milky Way galaxies.
Named after the Incan counting system, Quipu visually resembles a web of interconnected strands of galaxies and clusters.
Its discovery raises questions about the cosmological principle, which assumes the universe is uniform at large scales, and its implications for measuring cosmic expansion rates like the Hubble constant.
Quipu is one of five massive superstructures recently identified, collectively containing 45% of galaxy clusters and 25% of matter in the known universe.
