The large-scale structure of the universe refers to the pattern formed by the distribution of galaxies and matter across cosmic scales, organized into a cosmic web of filaments and dense clusters surrounding vast, comparatively empty voids. This structure grew from tiny density fluctuations present in the early universe, amplified over billions of years by gravitational attraction acting most strongly on cold dark matter. Large galaxy redshift surveys, which map millions of galaxy positions and distances, have been the primary tool for charting this structure and testing cosmological models against it.
Facts
Concept Domain Formulated YearMarks a landmark identification (the Great Wall), not the first observation of large-scale structure generally; earlier work identified superclusters and voids from 1983 onward. Proposed ByMapped incrementally by multiple survey teams from the 1980s onward; Margaret Geller and John Huchra's 1989 discovery of the Great Wall is recorded here as a landmark identification, not the structure's sole origin. 1 Connections
