AST 101 Lecture Notes - Lecture 24: Galilean Invariance, Michelson–Morley Experiment, Stellar Evolution
Document Summary
Imagine you are a very long lived astronomer from very far away. We are going to build a model of stellar evolution. This will be done completely out of other rules and observations that we can make about stars. Look at a lot of stars and develop a model of how all stars live and die. A. astronomers like to look at lots of different things because they have the telescopes to do it. The life of a single star is greater than that of the lifetime of an astronomer. C. when we look at lots of stars we see all of the possible ways that they can evolve since we are watching them go through their entire life. A physical property is on that is always the same no matter who measures it, or where in the universe the measurement is taking place. Mass we need to find in another way.
