Double Slit Experiment

The Challenge

The double-slit experiment shows that when individual electrons or photons are sent through a two-slit apparatus one at a time, they:

1. Build up an interference pattern identical to classical wave interference
2. Each particle creates a single detection event at a specific location
3. The pattern emerges gradually as individual detections accumulate
4. Which-path detection destroys the interference - if you measure which slit the particle went through, the pattern disappears
5. Delayed-choice experiments show the pattern depends on measurement setup decided after the particle has "already passed through the slits"

Quantum mechanics explains this through wave-particle duality: particles are both waves and particles simultaneously, with the wave function "collapsing" upon measurement.

Why This Matters

The double-slit experiment is frequently cited as the central mystery of quantum mechanics. Feynman called it "a phenomenon which is impossible, absolutely impossible, to explain in any classical way."

If AAM can provide a clear mechanical explanation using only waves in the aether (no wave-particle duality, no collapse), it would demonstrate that the "quantum mystery" is actually just misinterpretation of classical wave behavior.

Conventional QM Explanation

The Photon Picture

• Light consists of discrete photons
• Each photon is a "wave-particle"
• The photon wave function passes through both slits
• Upon detection, the wave function "collapses" to a single point
• The interference pattern emerges from quantum probability amplitudes

Key QM Claims

• A single photon "interferes with itself"
• The photon is "in a superposition of going through both slits"
• Measurement causes wave function collapse
• Which-path information is incompatible with interference (complementarity)
• No classical wave theory can explain this behavior

The "Impossibility" Claim

Bell and others argued that no local realistic theory (where properties exist before measurement and interactions are local) can explain:

• The gradual buildup of the interference pattern
• The fact that individual events are unpredictable
• The destruction of interference by which-path measurement

AAM Mechanical Explanation

What Actually Happens - The AAM View

1. Wave Emission from Source

• Conventional: A single photon (particle) is emitted toward the barrier
• AAM: A longitudinal pressure wave is emitted \(\unicode{x2014}\) a mechanical disturbance propagating through \(SL_{-2}\) aether (Axiom 7)
• The wave is caused by an atomic event at the source (e.g., planetron orbital perturbation within an active-star nucleon)
• Wave properties: definite amplitude, frequency, phase; exhibits two coupled aspects \(\unicode{x2014}\) density variation + orientation variation (what conventional physics measures as "E" and "B" field components)
• Wave propagates through aether medium at light speed (\(c\))

2. Wave Interaction with Two-Slit Barrier

• Conventional: The photon "goes through one slit OR the other OR both"
• AAM: The wave encounters both slits simultaneously
• Wave passes through both slits at the same time, with the same phase
• Each slit becomes a secondary wave source (Huygens' principle)
• Two waves emerge from the slits with coherent phase relationship

3. Wave Propagation to Detection Wall

• Conventional: The photon wave function interferes with itself
• AAM: The two pressure waves from the slits interfere \(\unicode{x2014}\) standard wave behavior
• Constructive interference: Where pressure maxima align, amplitude is maximum
• Destructive interference: Where compression meets rarefaction, amplitude cancels
• Creates spatial pattern of varying wave amplitude across detection wall
• This is identical to sound waves or any longitudinal pressure wave through a medium \(\unicode{x2014}\) pressure waves interfere classically, requiring no special quantum framework

4. Detection Mechanism (Critical Insight)

• Conventional: Wave function collapses, photon appears at random location
• AAM: Continuous pressure wave has limited amplitude and duration
• Wave pressure gradients act across detector atoms in the entire interference pattern region
• Most important: Wave amplitude varies with position (interference pattern)
• Detection occurs through direct wave-planetron coupling (Axiom 10): the wave's pressure gradients couple directly to the low-mass planetrons (\(\sim\)1/1836 of nucleon mass), which experience \(\sim\)1836\(\times\) greater acceleration than the massive nucleon anchor for the same applied force (\(a = F/m\))
• Threshold mechanism: When wave frequency matches harmonics of planetron orbital frequencies, resonance builds across 6\(\unicode{x2013}\)9 planetrons simultaneously (Axiom 1). At threshold, the combined destabilization ejects the planetron most strongly coupled to the incoming frequency \(\unicode{x2014}\) this ejected planetron is what conventional physics detects as an "electron"

Detection is probabilistic because:

• Wave amplitude is limited (finite motion in the pulse)
• Multiple detector atoms competing for resonance
• Thermal fluctuations and detector noise
• Exact timing of wave arrival vs detector atom state
• Each atom's planetron configuration is unique (Axiom 3: Particle Uniqueness Principle)

5. First Detection Event

• Where wave amplitude is highest, detection probability is highest
• Eventually (within microseconds) one detector atom's planetrons reach resonance threshold
• A planetron is ejected \(\unicode{x2014}\) detector "clicks" \(\unicode{x2014}\) registers the event
• This single click tells experimenters they sent a "single photon"
• But it was actually a pressure wave pulse of limited total motion (energy is derived from motion, not a substance \(\unicode{x2014}\) Axiom 7)
• The wave's motion has now been redistributed into the detector material

6. Pattern Buildup Over Many Trials

• Process repeats with each new wave pulse from source
• Each wave creates same interference pattern on detection wall
• Each detection event occurs at one location within that pattern
• Locations vary randomly, but weighted by interference pattern amplitude
• After many detections, the pattern becomes visible
• High-amplitude regions get more clicks (bright fringes)
• Low-amplitude regions get fewer clicks (dark fringes)

Quantitative Predictions

Interference Pattern Mathematics

Classical Wave Interference:

For two slits separated by distance d, waves from each slit travel different path lengths to reach a point on the detection screen at angle \(\theta\):

Path difference: \(\Delta L = d \sin(\theta)\)

Constructive interference (bright fringes) occurs when:

• \(d \sin(\theta) = n\lambda\) where \(n = 0, \pm 1, \pm 2, \ldots\)
• Waves arrive in phase, amplitudes add

Destructive interference (dark fringes) occurs when:

• \(d \sin(\theta) = (n + \frac{1}{2})\lambda\) where \(n = 0, \pm 1, \pm 2, \ldots\)
• Waves arrive out of phase, amplitudes cancel

Wave Amplitude at Screen

At position x on screen distance L from slits:

\( A(x) = A_0 \cos\left(\frac{\pi dx}{\lambda L}\right) \)

Where A₀ = amplitude of wave from single slit (factor of 2 from two slits interfering)

Detection Probability

AAM predicts detection probability proportional to wave intensity:

\( P(x) \propto I(x) = |A(x)|^2 \)

\( P(x) \propto \cos^2\left(\frac{\pi dx}{\lambda L}\right) \)

This exactly matches the observed interference pattern!

Experimental Validation

Tonomura's Single-Electron Experiment (1989)

• Electrons sent one at a time through double slit
• Pattern builds up gradually over hours
• Final pattern matches \(I(x) \propto \cos^2(\pi dx / \lambda L)\)
• AAM prediction: MATCHES

Quantitative Specifics

• Slit separation: \(d \approx 2 \, \mu\text{m}\)
• Wavelength: \(\lambda \approx 50 \, \text{pm}\) (for 50 keV electrons)
• Screen distance: \(L \approx 1 \, \text{m}\)
• Fringe spacing: \(\lambda L / d \approx 25 \, \text{nm}\)

AAM Explanation:

• Each electron event creates an aether pressure wave with \(\lambda = h/p\) (de Broglie relation)
• This wavelength emerges from planetron orbital structure in source atoms
• Wave passes through both slits
• Pressure wave interference creates pattern
• Detection occurs where wave amplitude exceeds planetron resonance threshold \(\unicode{x2014}\) planetron ejection
• Pattern gradually becomes visible as detections accumulate

Which-Path Detection Destroys Interference

The Experimental Observation

Setup:

• Place detector at one slit to determine which path the particle took
• Result: Interference pattern disappears
• Without which-path detector: Interference pattern visible
• With which-path detector: No interference, two separate single-slit patterns

QM Interpretation:

• Measurement "collapses" the wave function
• Gaining which-path information makes particle "real"
• Complementarity principle: Can't have both particle and wave information

AAM Mechanical Explanation

1. Detection Mechanism Perturbs the Wave

To detect "which path," the detector must:

• Interact with the pressure wave passing through the slit
• This interaction requires motion transfer from wave to detector (wave-planetron coupling drives planetron perturbation or ejection)
• Motion extraction reduces wave amplitude

2. Reduced Wave Amplitude Affects Interference

Original setup (no which-path detection):

• Full wave amplitude passes through both slits
• Strong interference pattern on detection screen

With which-path detector:

• Wave passing through monitored slit loses amplitude (motion extracted by wave-planetron coupling)
• Wave amplitude from two slits becomes unequal: \(A_1 \neq A_2\)
• Interference visibility reduced

3. Complete Destruction Requires Strong Interaction

For complete pattern destruction:

• Which-path detector must absorb significant wave motion (via planetron resonance coupling)
• This leaves minimal amplitude to create interference
• Remaining amplitude creates primarily single-slit diffraction pattern

Quantitative Analysis

Interference visibility:

\( V = \frac{I_{max} - I_{min}}{I_{max} + I_{min}} \)

• With equal amplitudes: V = 1 (perfect interference)
• With unequal amplitudes: \(V = 2A_1 A_2 / (A_1^2 + A_2^2) < 1\)

If which-path detector reduces amplitude to \(A_2 \approx 0\):

• \(V \rightarrow 0\) (no interference)
• Pattern becomes two separate single-slit patterns

Delayed-Choice Experiments

The Experimental Setup

Wheeler's Delayed-Choice Thought Experiment:

1. Particle/photon enters interferometer with two paths
2. After particle has "already chosen" its path, experimenter decides:
   • Option A: Measure which path (insert which-path detectors)
   • Option B: Recombine paths (allow interference measurement)
3. Result depends on final measurement choice, not initial state

QM Interpretation:

• The past is not determined until measured
• Retrocausality or "delayed collapse"
• Particle was in superposition even after passing through slits
• Final measurement determines what "already happened"

AAM Explanation: No Retrocausality Needed

1. The Wave Properties Are Always Definite

• Wave from source always has definite amplitude, phase, frequency
• Wave always passes through both paths/slits
• Wave properties don't depend on future measurements
• Nothing about the past changes

2. What Changes Is What We Measure

Interference Measurement:

• Allows waves from both paths to recombine
• Detector positioned to measure combined amplitude
• Result shows interference pattern

Which-Path Measurement:

• Prevents path recombination (inserts detection at path)
• Or: Measures idler photon in correlated pair
• Effectively destroys interference for those events
• Result shows no interference

3. The "Delayed" Part Is Irrelevant

The wave has already:

• Passed through both slits
• Created interference pattern in space
• Propagated to detection screen

The "choice" is about:

• Which aspect of the wave we measure
• How we set up our detector configuration
• What information we extract

Nothing travels backward in time. No retrocausality needed.

Summary

What This Accomplishment Means

For AAM

• Demonstrates wave-only explanation viable
• No wave-particle duality needed
• No wave function collapse needed
• Everything reduces to space, matter, motion (Axiom 1)

For Physics

• Challenges "impossibility" of classical explanation
• Shows Feynman's claim ("impossible to explain classically") was wrong
• Provides simpler alternative to quantum mysticism
• Restores physical reality to light propagation

Confidence Assessment: HIGH

This is actually much simpler than the entanglement challenge:

• Classical wave interference is well-understood
• No Bell inequalities to satisfy
• No complex correlation calculations
• Aether provides natural medium for waves
• Explanation more intuitive than QM

Connections to Other AAM Principles

Related Axioms

• Axiom 1 (v1.6): All phenomena reduced to space, matter, motion \(\unicode{x2014}\) no fields or forces as independent entities. Light is pressure wave motion in \(SL_{-2}\) aether matter. Detection mechanism: wave-planetron coupling drives resonant planetron ejection. Charge = chirality-surplus/deficit dual mechanism.
• Axiom 3 (v1.2): Particle Uniqueness Principle \(\unicode{x2014}\) no two particles exactly identical. Each detector atom has slightly different resonance characteristics, contributing to detection unpredictability.
• Axiom 6 (v2.0): Each wave has unique properties (amplitude, phase, frequency). Motion is continuous \(\unicode{x2014}\) waves trace continuous paths through aether.
• Axiom 7 (v2.3): Energy is derived from the motion of matter, not a substance. Motion conservation explains why which-path detection destroys interference (motion extraction reduces wave amplitude).
• Axiom 10 (v2.3): Aether is \(SL_{-2}\) matter \(\rightarrow\) structured particles with their own orientations and valence configurations. Wave-planetron coupling: pressure gradients couple directly to planetrons; nucleon (\(\sim\)1836\(\times\) planetron mass) acts as gravitational anchor. Symmetric State Principle: Aether stability as a wave medium explained by temporal scaling (\(\sim 3.7 \times 10^{22}\) faster processes at \(SL_{-2}\)). Source atoms contain nucleons that are active stars with iron cores.
