I frequently post in AskLemmy so I think about questions a lot. For example, I was thinking about this in the shower and I was thinking “I really like this handmade soap. It’s much better than the usual stuff we get” and then I came up with a related question: “What is something that you would rather buy handmade instead of mass-produced?”
I’m not so sure. What about an observation like “The empty set contains no elements.” ?
Which set contains no elements?
Or, more in the spirit of OP’s observation:
What are the fundamental rules for set theory?

Why is it empty? Should there even be something in there? If it’s blank variable before a loop, it probably should be empty before you start appending stuff in it. If that’s the case, great job. 👍
If you’re referring to the “empty set” and asking the question “why is it empty” you should probably step away from set theory for now.
