>>11158564Particles oscillating against a fluid medium, producing waves that carry momentum away from the particle, experiencing equal and opposite thrust as it transfers the momentum to the fluid medium. Particles have spin, this causes their trajectory to be circular, they are confined to a trajectory, at rest only in appearance, but never truly. The inertia of a mass is set by the local gravitational field intensity, or fluid pressure of the local medium. As the local gravitational field intensity approaches zero, the circular path of trajectory widens. The energy, no longer confined, ceases to be mass, and becomes radiation. If you strip a mass of its inertia, it explodes into electromagnetic waves.
