How do questions grow?

So many people ask whether there will be an end to questions. I don’t know where that idea comes from. Are people afraid of knowing too much? Could it be that they believe there is too much to know and they don’t want to deal with that? Why would you ask such a question?

Anyway, I wanted to turn that question on its head and ask where questions come from? How are they formed? Is it magic?

I don’t mean this in the scientific sense, where there is a formula for finding out what we don’t know and then trying to fill in that space. Space appears to be infinite, by the way.

It’s more like that way that questions just pop into your head. What is that all about?
