Elementary Particles - Spin Inversion Symmetry
At the moment I must call this a conjecture.
Spin Inversion Symmetry (SIS) says that every elementary particle of spin s has a dual particle of spin 1/s. Of course, SIS does not apply to the spin 0 Higgs. But it applies to all other elementary particles in the Standard Model and the hypothetical graviton.
So, assuming charge is conserved, the spin 1/2 neutrino has a neutral dual of spin 2. The spin 1 photon is its own dual. And the spin 1/2 electron has a charged spin 2 dual.
So SIS predicts a slew of new particles. Notice that the neutral spin 2 particles could also explain dark matter. However, as of now I don't have any underlying physics to justify SIS.
It's still a hunch.. or conjecture. But if true the implications are amazing.
