Man, that's me with elertroweak unification. I didn't really understand the weak force to begin with, so it being unified with another is so far beyond my capacity I just have to call it magic
Oh, that's easy! Just take your understanding of how spontaneous symmetry breaking works in QCD, apply it to the Higgs field instead, toss in the Higgs mechanism, and suddenly SU(2) × U(1) becomes electromagnetism plus weak force!
