When did Zwicky discover dark matter?
1933
During the early 1930s Zwicky contributed substantially to the physics of the solid state, gaseous ionization, and thermodynamics but soon turned to the study of supernovas, novas, and cosmic rays. In 1933 he discovered the existence of dark matter.
How did Zwicky discover dark matter?
In the 1930s, he noticed that galaxies within clusters were zooming around far quicker than their mass would logically dictate. So he figured that there must be some extra mass in there. Some sort of dark invisible matter slurping around the universe. And that’s what the matter with dark matter is.
What did Fritz Zwicky call dark matter?
Zwicky posited that an as-yet unobserved type of mass, dunkle Materie (dark matter) might explain it, and in 1933 he presented his findings in the journal of the Swiss Physical Society.
Did Rubin believe in dark matter?
Her data showed that stars at the edges of multiple galaxies were moving in ways that didn’t make sense, according to the rules of physics. One possible explanation for this strange phenomenon, Rubin suggested, was the existence of a mysterious “dark matter” at the edges of the galaxy.

Why is Fritz Zwicky important to astronomy?
On February 14, 1898, Swiss astronomer Fritz Zwicky was born. He is best known for his proposal of he existence of dark matter and counts as one of the most important astronomers of the 20th century. “To eliminate the discrepancy between men’s plans and the results achieved, a new approach is necessary.
Where did Fritz Zwicky go to school?
Fritz Zwicky attended a grammar school in Zurich, Switzerland and enrolled at the ETH Zurich in order to study physics and mathematics afterwards. Zwicky became a research assistant around 1922 and worked at the California Institute of Technology in Pasadena starting from 1925.
What did Frank Zwicky do for a living?
Zwicky became a research assistant around 1922 and worked at the California Institute of Technology in Pasadena starting from 1925. He received a scholarship by the Rockefeller Foundation. In California, he worked as a theoretical physicist and later astrophysicist at the observatories of Mt.Wilson and Palomar. [ 3 ]
What did Fritz Zwicky discover about supernovae?
He gained attention around 1933 when he coined the term ‘ supernova ‘ and theorized that they were most likely the transition of normal stars into neutron stars. In order to prove his hypthesis, Fritz Zwicky began hunting for supernovae. By the later 1930s, he is believed to have discovered more than a dozen of them.
