Moving so slow, / Clumping with gravity, / Making the galaxies!
007skaty Fritz Zwicky's 1933 cluster study and Vera Rubin's 1970s galaxy measurements showed how invisible dark matter keeps fast-spinning cosmic structures bound.
Dark matter mass: It makes up about 85% of all matter in the universe, meaning visible stars and planets are just a tiny cosmic minority.
A hypothetical form of matter that does not interact with light and is believed to make up most of the matter in the universe. Fritz Zwicky first postulated this invisible mass in 1933 while studying the Coma galaxy cluster.
