I once watched a nice talk about how scientists can inadvertently get “stuck” in a particular point of view because interpretations are often an A/B choice where both are valid. After taking a long path through many such interpretation choices it’s easy to loose track of the alternative points of view. The example in the talk was that “spacetime expanding” and “matter shrinking” are mathematically equivalent, and the choice is merely a preference between interpretations.
