A Short Range Force
  Gravitomagnetic and gravitoelectric forces have been studied for sometime and tests for detecting such forces arising from the earth, are under way. We apply similar considerations at the level of elementary particles in a formulation using General Relativity, and deduce the presence of short range forces. A possible candidate could be the somewhat recently detected but otherwise mysterious short range $B_{(3)}$ force, mediated by massive "photons".
