Quantum Tunneling: Vortex Incision-Passing and Instant Closure Mechanism

Based on the vacuum superfluid vortex cosmos theory, this paper proposes the "incision-passing and instant closure" mechanism of quantum tunneling. A particle is a high-speed rotating vortex ring in the vacuum superfluid, and its internal strong force is the confining pressure produced by high-speed rotation. During tunneling, the vortex does not stretch or form a ribbon; instead, a local incision directly passes through the thin potential barrier. Once the incision passes through, it rewinds immediately, and the entire vortex ring switches across the barrier instantaneously. The process requires no confrontation with the internal strong force, since the rear fluid keeps rotating continuously. The low probability of tunneling arises from the strict condition of counter-rotational fluid engagement, not from intrinsic quantum randomness.
