The researchers named this discovery “Quipu,” taking inspiration from the knotted string recording system once used by the Incas.
Observed as a long strand with smaller threads branching off, the Quipu superstructure contains 68 galaxy clusters with a combined mass of about 2.4 × 10^17 solar masses.
Its size of roughly 1.4 billion light-years makes Quipu the largest superstructure ever accurately measured, surpassing the Sloan Great Wall’s 1.1 billion light-years.
