explanation is a strange sort of food – a larger portion is not necessarily harder to swallow. A theory may be superseded by a new theory which explains more, and is more accurate, but is also easier to understand, in which case the old theory becomes redundant, and we gain more understanding while needing to learn less than before.
Better explanations simplify. They require fewer functional parts, which makes them harder to vary, to explain reality in a falsifiable way. They’re better fit to reality. Explanations don’t grow exponentially as we learn more. Rather, there become fewer and simpler explanations that lead to greater understanding.
