I was watching a video of Richard Feynman, the physicist, and an interviewer asked him to explain magnetic repulsion. (The video can be seen here.) In the video, Feynman explains that he cannot actually answer the question because it keeps unraveling into further deeper questions.
Essentially, that in order to answer the question, there is a point where we must assume an axiomatic acceptance of the world around us, or we'll just keep becoming mired in further and further questions that underlie the original question.
As a parent, scientist, and general know-it-all, I frequently get asked questions like this. They seem simple on their face, but cannot be adequately explained without a great amount of background.
Is there a word for this type of question?
I'd like to be able to warn people:
I'm sorry, but your question is [word for not as simple to answer due to the above problem] ... Are you sure you want to know my answer?
