The Standard Model for Neutrinos

We don't understand if neutrinos get mass the same way other particles do through the Higgs boson, or if they're a really weird particle. So neutrinos are sort of the next frontier like a part of the standard model that we've only just begun to explore and haven't nailed down very well. There's so many things we couldn't even cover them all. One of my favorites is whether there are particles out there that have just a north or just a south magnetic charge.
