WebDec 11, 2024 · 1 Massive and Bimetric Gravity Considering gravity in the field-theoretical framework, a natural theoretical question arises to whether the graviton particle itself could be a massive particle. In the same way as the particles in the standard model acquire a mass, could the spin-2 particle be endowed with a mass term? kid rock mount pleasant
