Spin angular momentum in the light of the fluctuon model

The dynamics of spin angular momentum in the fluctuon model of virtual particle exchange parallels the dynamics of linear momentum. The initiation and termination of spin 1 chains (photons, gluons, gravitons) is always associated with a change in the state of motion, or acceleration, of the absorbing particle and therefore with a compensating change in the angular momentum of the universe. The pattern of graviton exchanges in the universe will be altered, even if the initiated particle is not a graviton. This is required by the principle of equivalence, since the acceleration produced by chain initiation or termination cannot be distinguished from a gravitational effect. The analysis allows intrinsic spin to be given an extrinsic (Machian) interpretation in terms of the angular momentum state of the surrounding universe.
