Mapping the entire matter in the universe is an extremely challenging task and current technology is not advanced enough to accomplish it. However, scientists have made significant progress in mapping the large-scale structure of the universe and studying the distribution of matter on smaller scales. Scientists have made significant progress in mapping large-scale structures, but the universe is vast and much of it remains unobserved, making it difficult to produce a comprehensive map. The current best understanding of the distribution of matter in the universe comes from a combination of observations and simulations. A group of scientists has published one
