This is just an idea I had, but I can't seem to find any obvious flaws with it. It's pretty clear that the only description we have of fermions is as quantum objects. There is just no classical analog! Bosons however, have a very natural classical analog. If you just treat the quantum fields in the SM lagrangian as classical fields, you have a classical wave theory of bosons! So my idea is what if bosons aren't actually quantum objects like fermions? What if "bosons" are actually classical waves obeying classical laws? As far as I can see, there is no contradiction here with any experiment, since EVERY experiment we have is built with fermions! So any classical wave would go through a kind of "quantum filter" and would end up looking like another quantum wave. I know this is a strange concept, and I'm not suggesting it is correct. I am just curious if anyone can prove it wrong? It would probably require a reformulation of QFT to remain consistent with experiment, but I don't really see any major problems with it..
