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:

I soon became convinced... that all the theorizing would be empty brain exercise and therefore a waste of time unless one first ascertained what the population of the universe really consists of.

Fritz Zwicky

Mountains were once my big adventure but is is over since a long time; I still dream from the wonderful days sometimes, read also a few pages from a mountain book. But the thought of doing again active mountain climbing has faded.

Every evening, I come home tired and have just enough energy to fill out the endless tax forms, to pay bills, not to let my house neglected and to hear the radio concert for an hour.

I myself can think of a dozen ways to annihilate all living persons within one hour.

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.

I have a good idea every two years. Give me a topic, I will give you the idea!
