When was dark matter first inferred from galaxy rotation curves?
Quick Answer
In 1970, Vera Rubin and collaborators reported galaxy rotation data that strongly implied unseen mass, now called dark matter.
The Full Story
In 1970, Vera Rubin and colleagues published influential observations showing that stars in spiral galaxies orbit too fast to be held together by visible matter alone. Their galaxy rotation curves suggested the presence of a large amount of unseen mass. This unseen material is now called dark matter. Rubin’s work became one of the foundations of modern dark matter research, even though the substance has never been directly detected.
