FAQ About Vera Rubin
What was Vera Rubin's contribution to the discovery of dark matter?
Vera Rubin's most significant contribution to the discovery of dark matter was her detailed study of the rotation curves of galaxies. By analyzing the speed at which stars and gas clouds orbit the center of galaxies, she found that the outer regions rotated as quickly as the inner parts, suggesting the presence of an unseen mass. This unseen mass, later referred to as dark matter, constitutes about 27% of the universe's mass-energy content.
