Astronomers have discovered Quipu, the largest known cosmic structure, spanning 1.3 billion light-years and reshaping our understanding of the universe's formation.

About Quipu

• This superstructure has mass of 200 quadrillion solar masses and stretches over 1.3 billion light-years. 
• Superstructures: Extremely large structures containing groups of galaxy clusters and superclusters.
• 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.
• 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.

Effects of Superstructures:

• Cosmic Microwave Background (CMB): Superstructures cause fluctuations in the CMB (relic radiation from Big Bang).
• Hubble Constant: Superstructures distort accurate measurements of the Universe's expansion rate.
• Distort sky images due to gravitational lensing (GL).
• GL occurs when a massive object, like a superstructure, bends light from background sources.
