The Vacuum as a Two-Walled Frictionless Slip Interface: A Possible Matter Formation Bias

This paper develops the laminar wall-slip hypothesis within the two-walled, pressure-bearing thin-gap model of the vacuum introduced in papers R190 through R193, which the author refers to as Model 3. The central proposal is that the inner and outer limiting surfaces of the Planck-scale vacuum gap may undergo frictionless tangential relative motion. In this interpretation, the vacuum gap is not merely a static separation but a regularized slip interface: two surfaces remain distinct because they are in laminar relative motion, while the tiny gap prevents the interface from becoming a singular discontinuity. The present paper further proposes that the inner portion of the universe may conserve angular momentum relative to the outer wall. As cosmic expansion increases the effective moment of inertia, the angular slip rate decreases geometrically rather than dissipatively. A minimal toy model gives omegaₛlip proportional to a^-2 and vₛlip proportional to a^-1. This allows present-day wall slip to be very slow, weakly coupled, or effectively invisible, while still having been stronger in the young universe. The paper also explores a possible matter-antimatter formation bias: wall slip may not directly determine particle topology, but it may have produced a small directional pressure asymmetry during early rotor closure, making one matter-like formation orientation slightly more probable than its antimatter counterpart. The hypothesis remains exploratory and requires explicit two-wall variables, a slip-pressure law, and particle-formation simulations before it can become a quantitative part of Model 3.
