Fritz Zwicky quotes
Fritz Zwicky was a Swiss-American astrophysicist renowned for his pioneering work in galaxy clusters and dark matter. His discoveries and unconventional ideas significantly influenced the development of modern astrophysics. He made groundbreaking contributions to concepts such as supernovae and the existence of unseen cosmic matter. Here are 7 of his quotes:
It is known that very distant nebulae, probably galactic systems like our own, show remarkably high receding velocities whose magnitude increases with the distance. This curious phenomenon promises to provide some important clues for the future development of our cosmological views. It maybe of advantage, therefore, to point out some of the principal facts which any cosmological theory will have to account for. Then a brief discussion will be given of different theoretical suggestions related to the above effect. Finally, a new effect of masses upon light will be suggested which is a sort of gravitational analogue of the Compton effect.
