Large-scale structure refers to the organization and distribution of matter in the universe on very large scales, typically ranging from hundreds of millions to billions of light-years. This includes the formation and distribution of galaxies, galaxy clusters, filaments, and voids in the cosmic web. Studying the large-scale structure of the universe can provide important insights into the fundamental properties of the universe, such as its overall geometry, the nature of dark matter and dark energy, and the mechanisms driving the evolution of the universe. Researchers use a variety of observational techniques, such as galaxy surveys and cosmic microwave background measurements, as well as theoretical models to study the large-scale structure of the universe.
