Quipu is a proposed cosmic structure of galaxies, known as a galaxy filament. It was proposed in late 2024 by Böhringer and colleagues while analyzing data from the CLASSIX sample of galaxy clusters from the ROSAT All-Sky Survey.[1] It would be one of the largest known cosmic structures, with a projected length greater than 400 megaparsecs (1.3 billion light-years)[2]
and an estimated mass of 2 × 1017 M☉.[2]
Named after the ancient Inca knot writing, the Quipu is visualised as an intricate, filamentary network of galaxy clusters, superclusters, and voids, forming a vast cosmic web. This structure would be the largest scale of organization in the universe, emerging from the gravitational clustering of dark matter and baryonic matter over cosmic time.[1][3]
