Biography of Astronomer, Vera Cooper Rubin

She has been involved in many scientific associations such as the American Science Promotion Association, the American Philosophical Association, the International Astronomical Union, the National Academy of Sciences, the Phi Beta Kappa Association and the Papacy Academy. The famous For-She is best known for providing a large amount of persuasive evidence with Dr. Kent Ford who prove Fritz Zwicky's darkness. Existential Problem 2 Zwicky states that individual galaxies in a cluster of coma movements move very fast if they are controlled only by their attractive forces of visible light.

Vera Florence Cooper Rubin (/ ruːgɪn /; July 23, 1928 - December 25, 2016) is an American astronomer who pioneered research on galactic rotation speed. By studying the galactic rotation curve she reveals the difference between the anticipated angular movement of the galaxy and the observed motion. This phenomenon is known as the problem of galactic rotation, and is evidence of the presence of dark matter. Originally suspected, Rubin's results were confirmed in the next few decades. Her heritage was expressed by the New York Times as "Introduction of Copernicus scale change in cosmology".

The first clues to the existence of dark matter come from the speed at which stars rotate within the galaxy. Observational astronomer Berarbin made detailed quantitative measurements of stars that rotated the galaxy from the late 1960s to the early 1970s. The characteristics of a galaxy, such as the velocity of its star orbit, depends on how much it contains the substance. Only when there are visible substances, it is expected that the stars far outside the Milky Way are not quite sensitive to their gravitational pull. However, Rubin discovered that stars away from luminescence center material rotate at the same speed as the 1 / 10th star in the center of the galaxy. This means that the mass density does not decrease with distance, at least up to the distance Rubin observed. Astronomers conclude that galaxies are mainly composed of invisible dark matter.
