If you have ever read Feynman’s (in)famous first Lecture on Quantum Behavior, you know the dogmatic line by heart. Feynman introduces his famous thought experiment with a machine gun shooting “bullets” or billiard balls through a pair of slits. He asserts that a classical bullet going through a single open slit can only ever produce a smooth, featureless bell curve on a backboard. Because real electrons produce a highly structured multi-peak diffraction comb instead, Feynman famously declares that electron interference “is absolutely impossible to explain in any classical way” and contains the “one and only mystery” of quantum mechanics.
For a century, mainstream physics has used this “mystery” as an ideological fortress, telling students to shut up and calculate while treating the electron as a zero-dimensional point particle riding a mystical, unobservable cloud of multi-path wave functions.
But what if Feynman’s modelling of electrons as”bullets” was completely wrong from the very start?
The Scale Surprise: Billiard Balls Don’t Touch the Tunnel
In our latest paper, Lecture Y-9, we decided to establish a rigorous, pure mechanical baseline using the actual micro-scale physical dimensions from the landmark 2012 University of Nebraska-Lincoln (UNL) electron diffraction experiment (Bach, Pope, Sy-Huan, and Batelaan).
When you look at the real hardware scales, something striking emerges. The electron gun is located 16.5 cm away from a 2 micrometer collimation slit. For an electron to even enter that window, its maximum entry angle can be no more than an infinitesimal 6 10-6 radians. As that electron flies through the100 nanometer thick silicon-nitride slit membrane, its maximum possible lateral drift inside the tunnel is just 0.6 picometers!
Because 0.6 pm is completely negligible compared to a 50 nm wide slit, over 99.99% of the electrons pass straight through the tunnel without ever colliding with or touching a mechanical wall.
This mathematical reality proves Feynman’s intuition was right only if you assume a completely passive, dead environment. A pure ballistic model leaves the electron isolated, producing a flat block on the detector screen. To understand real data, we have to look at the active, electrodynamic reality of the apparatus.
Enter RealQM: Three Models for Common-Sense Physics
In a Structural Realist (RealQM) framework, we return to plain common-sense physics. The gold-plated walls of the UNL slit aren’t passive voids—they are a mobile sea of conduction electrons surrounding a crystal lattice. The electron isn’t a structureless point—it is an extended, circulating toroidal field soliton with a real Bohr magneton magnetic moment and an internal Zitterbewegung rotation phase.
Working with Gemini, we wrote an open-source trajectory engine to simulate what happens when you let an extended particle interact with this active electrodynamic landscape. We built three distinct models to see which one accurately maps reality:
- Model 2 (Electrostatic Image-Charge Pull): We modeled the negative electron inducing a positive image charge in the gold plates. This creates a deterministic, attractive outward force. It acts as a diverging lens, widening the single-slit patterns and deepening the central gap—proving electrostatic wall attraction alone cannot be the trick.
- Model 3 (Toroidal Dipole Gradient Torque): We modeled the electron’s magnetic moment cutting through localized magnetic field gradients near the gold boundaries. Because the force depends on the electron’s arrival phase, the gradient acts as a convergence lens, sorting trajectories and funneling them inward to fill the central gap completely—even when only one slit is open!
- Model 1 (The Effective Mass Matrix Lens): Derived directly from Annex I of Lecture Y-8, this is the optimal engine. Because the electron has finite spatial extension, crossing the field gradients deforms its geometry and varies its transverse effective mass matrix M-1(x)\). The slit acts as a coordinate-dependent refractive index gradient—a geometric phase-sorting lens.
Caustic Resonance Combs and Path Additivity
When you run Model 1, the featureless mechanical blocks vanish. Trajectories natively bunch up into highly discrete, localized geometric folding zones called caustics.
Without generating a single complex wave amplitude, the simulation beautifully reproduces the primary central peak, the symmetric secondary lobes, and the sharp dark fringes seen in real-world quantum diffraction!
Best of all? Particle conservation is exactly 100.000%. If you run Slit 1 open (P1) and Slit 2 open (P2) independently, they stack together perfectly to form the double-slit profile through simple linear addition:
P12 = P1 + P2
No wave-function collapse, no multi-path mysticism, and no non-local ghost forces. The apparent “interference” is entirely a property of independent, individual particles reacting deterministically to a localized field metric.
