What is Quipu?

Feb. 11, 2025

Astronomers recently identified what could be the largest structure ever found in the known universe, named Quipu.

About Quipu:

  • It is a recently discovered superstructure in which galaxies group together in clusters and clusters of clusters (superclusters).
  • It contains nearly 70 galactic superclusters.
  • It is the largest known structure in the universe in terms of length.
  • Quipu stretches an astonishing 3 billion light-years across and contains an estimated 200 quadrillion solar masses.
  • It is over 13,000 times the length of the Milky Way.
  • It is also hundreds of thousands of times more massive than a single galaxy.
  • Inspired by the Incan counting system of knotted cords, the structure mirrors its namesake with a long central filament and multiple branching filaments.
  • Despite its vast size, Quipu will not last forever. Scientists believe it will eventually break into smaller, collapsing units.
    • They describe it as a "transient configuration" that will change over time.
  • Studying Quipu may help refine cosmological models. It could offer new insights into galaxy evolution and large-scale cosmic dynamics.
