Wave Function Interpretation
SpeculativeWhat does ψ (the wave function) actually describe? Copenhagen says it's our knowledge. Many-Worlds says it's everything that exists. Bohmians say it's a guiding field. Synchronism offers a different answer: ψ describes phase patterns in the coherence field.
ψ as Phase Pattern
In Synchronism, the wave function is neither epistemological (about what we know) nor ontological in the Many-Worlds sense (a branching multiverse). It is a description of how coherence is distributed across a system's configuration space. The wave function is real, but what it describes is coherence structure, not matter or probability.
What |ψ|² Means
|ψ|² = coherence distribution.
The squared modulus of the wave function gives the coherence density at each point in configuration space. Regions with high |ψ|² have high coherence — the system's phase pattern is concentrated there. The Born rule (P = |ψ|²) follows because measurement probabilities are proportional to coherence density.
Collapse as MRH Crossing
The most contentious aspect of the wave function is collapse: the abrupt transition from superposition to a definite outcome upon measurement. Synchronism reframes this:
Before Measurement
ψ describes a spread-out phase pattern. Coherence is distributed across multiple branches. γ is high. The system is within its own MRH — all branches are mutually relevant and can interfere.
During Measurement
The system couples to a macroscopic apparatus. Ncorr increases rapidly. γ drops. The MRH contracts. Different branches of the superposition become mutually irrelevant — they cross each other's MRH.
After Measurement
Each branch exists independently beyond the other's MRH. From within any branch, the system appears to have “collapsed” to a definite outcome. But no physical discontinuity occurred — only an MRH boundary crossing.
Comparison of Interpretations
Copenhagen
ψ = knowledge. Collapse = updating our information. Problem: whose knowledge? What counts as measurement?
Many-Worlds
ψ = reality. No collapse; all branches exist. Problem: why do we experience probabilities matching |ψ|²?
Bohmian
ψ = pilot wave guiding real particles. Problem: non-local, requires preferred foliation of spacetime.
Synchronism
ψ = phase pattern. Collapse = MRH crossing. No observer needed. No multiverse required. No hidden variables.
Key Distinction: Collapse Is Not Physical
In Synchronism, wave function collapse is not a physical event. It does not require consciousness, it does not violate unitarity, and it does not create new branches of reality. It is a boundary crossing — the point at which correlations between branches become irrelevant. This is as physical as a star crossing the cosmic horizon: nothing happens to the star, it simply becomes inaccessible from our vantage point.
This interpretation does not change the predictions of quantum mechanics. It changes what the formalism means. Whether that constitutes progress or mere relabeling depends on whether you think the measurement problem is a real problem.
