The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy ...
New research has improved the accuracy of the parameters governing the expansion of the universe. More accurate parameters will help astronomers determine how the universe grew to its current state and how it will evolve ...
