Spin Inversion Symmetry - Predicting the Graviton
I would like to make a conjecture and call it Spin Inversion Symmetry. It says: Every elementary particle in the Standard Model (except the Higgs) of spin s has a partner of spin 1/s.
So the fermions (spin 1/2) in the Standard Model would have spin 2 partners and the bosons (spin 1) in the Standard Model would be their own partner.
Of course, for this to work we need to have at least one spin 2 particle. Maybe many more. So gravity appears automatically.
