The cosmic web is a large-scale structure of the universe consisting of interconnected filaments of galaxies and clusters of galaxies separated by vast regions of voids. These filaments can span millions of light years and are thought to be formed by the gravitational collapse of dark matter and gas in the early universe. Understanding the cosmic web can provide insights into the distribution of matter in the universe, the formation and evolution of galaxies, and the overall structure of the universe. Observational techniques such as galaxy surveys, simulations, and computational models are used to study the cosmic web.
