I would like to pose a question to the pure Rambamists.
Rambam's son, Rabbi Avraham, in his introduction to the Agadot, printed in Ein Yaakov, that if modern scientist prove beyond a doubt that our previous understandings on science were wrong, the halacha must conform to the modern scientists.
Rambam's Hilchot Yesodei Hatora, chapters 3 and 4, contains many scientific ideas that have been proven wrong by modern scientists.
So what do you do? Follow Rambam even in these cases or allow for other viewpoints?
