The toroidal boundary
RSI holds that expansion is a finite phase, ending when the field's tension turns matter back into the Universal Inhale.
RSI addresses accelerated expansion without Dark Energy by treating the Exhale as a finite phase of the toroidal circuit. Expansion does not continue forever into an infinite void.
As matter reaches the outer rim of the Eternal Consonance, the medium follows a refractive rollover set by the field's streamlines. Picture the surface of a doughnut: flow that moves outward along the top curves over the edge and returns along the underside. In RSI, the 0.73 N tension acts as an elastic limit at this rim. It captures the matter-knot and refracts it into the return current of the Universal Inhale.
The theory holds that this explains why the observed expansion (redshift) aligns so closely with the Bulk Flow (blueshift) toward the Still Core. The two are not competing motions. They are different segments of the same closed-loop mechanical engine, with the outward Exhale and the returning Inhale forming one continuous circuit.
