The structure of the universe is a vast and intricate tapestry woven from galaxies, stars, and cosmic voids, shaped by the interplay of gravity and dark energy. At the largest scales, the universe is organized into a web-like structure known as the cosmic web. This web comprises filaments of galaxies and clusters that stretch across vast distances, with immense voids in between where very few galaxies reside. Observations reveal that galaxies are not distributed evenly; instead, they cluster together, forming groups and superclusters. This large-scale structure is a direct consequence of the gravitational effects of both visible matter and the unseen components of the universe, namely dark matter.
