could time be the force carrier of mass? in other words maybe time is to mass sort of what electromagnetism is to photons. if so then we won't find a the Higgs boson because there isn't a conventional particle to detect. can we treat time like a particle in existing models?
if mass has a latency the residual dimple in space / time of a mass could have leave a measurable furrow that becomes shallower over time. you could check colliding galaxies to see if this is true, the 'dark matter' will dissipate.
