  80  ∃ (outer : RSUniverse), ∀ n, outer.events n ≠ u.events n

  82/-- **THEOREM IC-004.3**: The simulation predicate is not provably true for any RS universe.
  83    This formalizes: "there is no fact of the matter" about simulation in RS.
  84    Any "outer-universe" would itself be an RS universe with the same structure. -/
