Ben Levi,
It’s no “caricature”. I have read all of Rabbi Millers material on the subject and his view has been the mainstream view in Yeshivish circles for quite some time now. He clearly wrote and said that all modern science that contradicts Chazal’s scientific statements are “Hoaxes” and “Insanity”. ( I remember listening to a tape of his years ago called “The Hoax Of Geology” where he claims to disrove all of the findings of modern geology that contradict the simple meaning of Chazal’s statements)
