Fritz Zwicky

Fritz Zwicky

astronomer Switzerland

Fritz Zwicky was a Swiss astronomer and astrophysicist noted for his pioneering work in the field of cosmology and his formulation of the concept of dark matter. He proposed the existence of dark matter to account for discrepancies in the observed mass of galaxy clusters. Zwicky was also known for his 'tired light' theory, which suggested that the redshift of light from distant galaxies was due to energy loss rather than the expansion of the universe, a controversial idea that has sparked much discussion in the scientific community.

Born on Feb 14, 1898 (127 years old)
