I won't give much away, but basically Fermilab had a result that if verified to the full 5 sigma would mean that the standard model of physics is either wrong or at least is missing something.
I really like how this video is essentially her explaining it to the crew on set. Not scripted, but a very talented science communicator explaining a mind bogglingly complex phenomenon to lay people in an accessible way.
I highly recommend a watch and subscribe to her channel. The video she did on explaining mirrors many moons ago had me hooked.
