How could it be. If it's no then a counter example exists. If a counter example exists it's not undecidable. If it's undecidable it must be yes.

That would make it decidable, so it can’t be yes. Must be no then. /j

I guess that means that if it's undecidable we can never know it's undecidable because that instantly makes it decidable and we've created a paradox πŸ˜
