This is a wide-reaching question and may well be met with a blank expression. It's like saying, 'What happens on Planet Earth?' It's a question that could take a long time to answer because of its non-specificity. It may be more helpful to narrow down the range of the question a little to: people, places or things.
かなり広範囲に及ぶ問題であり、空白だけで満たされる可能性があります。それは、「What happens on Planet Earth?：地球で何が起こっているの？」と尋ねることと同じで、特になんの名産もないがために答えるのに時間がかかるかもしれない質問です。質問の範囲を人、場所、物などに少し絞ることがより効果的だと思います。
