> Both of those corrections are absolutely part of the model

Is there a way to gain a better understanding of how these parameters are modeled and what the scientific evidence is for the various phenomena in astrophysics? It's somewhat perplexing to me as an outsider of the field to understand how things like mass and distance of stars and planetary bodies are determined when 1) the scales are so outside of conventional experience 2) observation is limited to 2D imaging of the night sky 3) the observations in general are not consistent with our knowledge of gravity and relativity without adding hidden parameters.

I know Terence Tao (yes, that Terence Tao) is working on a book about the cosmic distance ladder, but sadly it's not out yet. (I guess he probably has other projects he's working on.) But he does have some slides from talks he's given: https://terrytao.files.wordpress.com/2020/10/cosmic-distance...
