Astronomers have discovered the Quipu superstructure, the largest known cosmic formation, spanning 1.4 billion light-years and containing 68 galaxy clusters.

Identified using X-ray data from the ROSAT satellite, Quipu surpasses the Sloan Great Wall and challenges assumptions about large-scale matter distribution.

The find raises questions about the cosmological principle, which suggests uniformity across vast distances.

Named after the Incan knotted recording system, Quipu highlights how massive structures shape cosmic evolution and may refine calculations of expansion rates and fundamental universe parameters.
