The Roll-Over Rim

In RSI, the edge of the universe is not a physical wall. It is the place where outward momentum is resolved. This is the second of the theory's two resolution zones, the counterpart to the Still Core at the center.

After the Big Break, galaxies move outward in the Exhale. Near the rim, the tension of the undisturbed field turns them back. The outward motion of the Exhale continues until the outward kinetic energy of the Exhale is exactly balanced by the Universal Baseline Potential, which is the tension of the undisturbed field.

At that boundary, the outward motion stops. Matter no longer has the pressure to keep moving outward. The external field tension then forces it to curve back inward. RSI calls this turn the Toroidal Roll-Over. It is the bend at the outer edge of the doughnut-shaped circulation along which matter turns from the Exhale into the returning Inhale.
