Something is up with muons. They are not behaving in the way we would expect. Does this mean our model of the universe is wrong? Lily explains to her Dad what is going on, why the Standard Model is always evolving, and just what on earth the Standard Model is anyway. She is helped by Dominika Vasilkova, a PhD student at University College London who works on Fermilab’s g-2 experiment - the actual experiment which is bringing the strange behaviour of muons to light.
