And if Quipu's extremely large mass doesn't garner attention, its size surely does. The object, called a superstructure, is more than 400 megaparsecs long. That's more than 1.3 billion light-years. A structure that large simply has to affect its surroundings, and understanding those effects is critical to understanding the cosmos. According to new research, studying Quipu and its brethren can help us understand how galaxies evolve, help us improve our cosmological models, and improve the accuracy of our cosmological measurements.
