Can spin 2 yield rest masses?

  1. Aug 25, 2004 #1
    Would a massless spin 2 boson travelling at light speed collide with a fermion to yield particle-antiparticle pairs (if the spin 2 was a graviton the particles would have to have a very small mass so far undetected by science)?
    Could this spin 2 boson be electromagnetic in nature?
    Could a collision with a fermion produce more than one particle-antiparticle pair per boson? And could bosons turning into fermions in a space saturated with fermions cause that space to expand (in analogy with neutron degeneracy pressure) - can dark energy be accounted for by massless spin 2 becoming spin 1/2 with rest mass?
