History

Historical Context

Astronomers' discovery of a massive dark matter clump in the Perseus cluster ties into the historical study of dark matter, which gained traction in the 1930s with Fritz Zwicky's observations of galaxy clusters. Vera Rubin's later work in the 1980s confirmed that galaxies are surrounded by dark matter halos, revolutionizing our understanding of cosmic structure and evolution, paving the way for today's advancements in cosmology.
