I wrote it on one sentence to make it short, but this deserves paragraphs of explanation. Let me try to make it in the middle (we will always have time later for paragraphs).
We have a lot of theoretical frameworks proposing how to extend the Standard Model (and thus explaining how the universe works). All these frameworks predict new phenomena beyond the Standard Model. Therefore, observing some new phenomena, together with non-observing others, will help us to clarify what are the possible options and what are not.
Does it clarify it?
