Dark Matter's Dominance
- Dark matter makes up a significant portion of the universe, much more than visible matter.
- It doesn't interact with light, making it invisible to us.
Zwicky's Early Hints
- Fritz Zwicky's study of the Coma Cluster in the 1930s provided early hints of dark matter.
- He observed that galaxies moved faster than expected, suggesting unseen mass.
Rubin's Confirmation
- Vera Rubin's research in the 1970s solidified the dark matter theory.
- She found stars at galaxies' edges moved faster than expected, defying predictions.
