What Makes a Question 'Unanswerable'?

Imagine asking your friend, 'What is the color of happiness?' They might say blue, or yellow, but there's no right answer. Some questions are like that: they don't have a single answer, and that’s what makes them unanswerable. It doesn’t mean they’re silly, it means they're deep.

Sometimes the question itself changes while we try to answer it, or there's no clear way to know the answer. Like asking, 'What is the beginning of time?' If time has no start, how can we say what came first?
