Natural Quantum Theory (NQT): A Manifesto

— Let Nature speak again —

Executive vision

  • We end the mystification of quantum mechanics and restore a clear, realistic, and causal picture of nature.

  • Quantum theory is re-grounded as a spectral description of continuous, local field dynamics under explicit boundary conditions—without point particles, magical collapses, or superluminal causes.

  • Discreteness (quanta) is not an axiom but the natural consequence of resonance and boundary constraints; “quantum states” are spectral modes of extended fields with finite size (≈ Compton scale).

  • Mathematics serves mechanism: wavefunctions are representations, not things; probabilities are ensemble summaries, not ontological fuzz.

1) First principles (what NQT affirms)

  1. Realism and continuity

  • Simple: The world exists and evolves regardless of observation; measurement reveals, it does not create.

  • Technical: Physics describes continuous fields and extended structures whose dynamics are causal and local in spacetime.

  1. Finite size and extended structure

  • Simple: Quanta are not points—think tiny, stable field whirlpools at roughly the Compton scale.

  • Technical: Extended charge and current distributions with real geometry remove point-like pathologies and anchor all conserved flows (energy, momentum, angular momentum).

  1. Quantization from boundaries (not from fiat)

  • Simple: Like a guitar string, stable modes are discrete because the system is bounded and resonant.

  • Technical: Discreteness emerges from boundary conditions and charge quantization; h sets the spectral scale, not a metaphysical “quantum essence.”

  1. Wavefunction as representation, not substance

  • Simple: The wavefunction encodes a system’s spectral content; |ψ|² reflects energy-density/ensemble statistics, not an object smeared over space.

  • Technical: Schrödinger theory is a frequency-domain tool; it projects rich, local field dynamics into a compact spectral basis.

  1. Local causality; entanglement as correlation

  • Simple: No faster-than-light influence; “entanglement” records shared origin and constraints, not spooky action.

  • Technical: Correlations arise from common spectral modes and boundary histories; phase coherence preserves relational structure without violating locality.

  1. Spin and magnetic moment are physical

  • Simple: Spin is real rotation of an extended distribution; the magnetic moment is its tangible footprint.

  • Technical: Angular momentum and magnetic energy are carried by circulating fields; g-factor anomalies trace to finite structure and self-interaction, not pure algebra.

  1. Gauge as bookkeeping of physical orientation

  • Simple: Gauge freedom tracks local phase/orientation choices; it is not a hidden realm.

  • Technical: Potentials coordinate consistent orientation of moments and phases across space; Aharonov–Bohm is local phase modulation of extended fields.

  1. Vacuum and infinities demystified

  • Simple: Only differences are observable; infinities flag unphysical point models.

  • Technical: Finite structure (shape factors) regularizes UV behavior; spectral differences (Casimir-style) are physical, absolute vacuum sums are not.

  1. Measurement as boundary redefinition

  • Simple: Measurement changes the setup, not reality’s ontology; Zeno/anti-Zeno are control of coupling and constraints.

  • Technical: System–apparatus interaction reconfigures global boundary conditions and mode occupancy; no ad hoc collapse postulate is required.

  1. Education and clarity

  • Simple: Teach mechanisms and fields first; keep spectra and statistics honest.

  • Technical: Distinguish time-domain dynamics from frequency-domain representation; define “quantum state” precisely in both.

2) Methodological commitments (how NQT proceeds)

  • Mechanism before math: every formal object must map to a physical flow, density, or geometry.

  • Dual-domain rigor: analyze in time and frequency; never lose track of boundary conditions and locality.

  • Finite-structure regularization: build models with explicit shape factors at ≈ Compton scales; avoid point-idealization and post hoc renormalization.

  • Difference-only observables: compute spectral shifts, currents, and response functions; avoid absolute vacuum “energies.”

  • No new magic: add no axioms like collapse or superluminal influence; insist on causal narratives testable in the lab.

  • Reproducibility first: publish protocols, priors, and data; welcome adversarial replication.

3) Experimental program (what to test next) Near-term, discriminating tests that preserve quantum’s predictive success while probing its physical origin:

  • Free-particle coherence and trajectories

    • Ultra–high-vacuum electron-beam lateral spread: predict near-zero transverse diffusion vs. standard expectations when interactions are eliminated.

    • Sparse-track reconstructions: demonstrate continuous, causal trajectories under minimal perturbation.

  • Magnetic structure and spin

    • High-resolution Stern–Gerlach with tunable gradients and apertures: reveal continuous orientation dynamics of magnetic moments (beyond two-spot dogma).

    • Energy-balance in extreme B-fields: search for systematic deviations traceable to real magnetic energy storage in extended structures.

  • Time-resolved emission and “forbidden” transitions

    • Attosecond spectroscopy on nominally forbidden lines: map continuous mode-switching dynamics rather than instant “jumps.”

    • Mössbauer-like emission timing and recoil accounting: test non-instantaneous, lattice-coupled field relaxation.

  • Interference, AB, and “entanglement”

    • Aharonov–Bohm local-phase mapping with phase plates: visualize field-based phase accumulation without nonlocal narratives.

    • HOM/antibunching under controlled partial mode mismatch: validate coherent-field interference origin of coincidence dips.

    • “Entangled photon” re-analysis with mode engineering: test whether global-mode correlations suffice without invoking superluminal causation.

  • Finite size and g-factor systematics

    • Low-Q² elastic scattering at Compton-scale resolution: probe finite charge/current architectures.

    • Energy-dependent g-factor measurements: constrain self-interaction and structure contributions beyond perturbative fitting.

4) Theoretical work packages (what to build)

  • Spectralization principle

    • Derive quantization as boundary-mode discreteness; make explicit the map from local field dynamics to spectral representation.

  • Schrödinger as a tool, not ontology

    • Re-express Schrödinger theory as an efficient frequency-domain solver for extended-field systems; recover Born statistics from energy-density/ensemble logic.

  • Extended-charge electrodynamics

    • Construct causal field models with finite geometry that reproduce bound states, spectra, and selection rules; include magnetic energy and torque.

  • Regularization by construction

    • Replace point-particle renormalization with finite shape factors; show automatic UV convergence and parameter emergence from geometry.

  • Gauge and geometry unified

    • Reinterpret U(1)/SU(2) gauge as orientation/phase kinematics of real modes; connect “mixing” to coherent rotation rather than abstract groups.

  • Strong-interaction picture (exploratory)

    • Treat color as internal phase–polarization texture; model confinement as closure of vorticity/phase loops (self-binding of field modes).

5) Education and culture (how we teach and talk)

  • Curriculum reset

    • From waves to spectra: start with classical fields, boundaries, and resonance; then introduce spectral methods as representations.

    • Define “quantum state” precisely (vector, wavefunction, density operator) and tie each to measurable energy densities and flows.

  • Demystify hallmark concepts

    • Replace “collapse” with boundary reconfiguration; “superposition” with spectral expansion; “spin” with real rotation and magnetic moment.

    • Present uncertainty as Fourier duality (methodological), not ontological fuzz.

  • Laboratory literacy

    • Center phase coherence, mode matching, apertures, and global constraints in all lab courses; treat detectors as dynamical amplifiers, not metaphysical agents.

6) Calls to action (who should do what)

  • Experimentalists: Prioritize the discriminating tests above; preregister designs and share raw data and analysis notebooks.

  • Theorists: Build finite-geometry field models that reproduce spectra, cross sections, and magnetic response without point divergences.

  • Quantum technologists: Re-express device operation in mode/field language; leverage classical signal-processing analogs where appropriate.

  • Philosophers of science: Clarify realism vs. instrumentalism in light of NQT; develop criteria for “representation vs. ontology” in spectral theories.

  • Educators and textbook authors: Publish NQT-aligned modules; make definitions explicit; remove mystifying language that halts mechanism-level inquiry.

  • Editors and funders: Support replication, negative results, and boundary-focused experiments; incentivize mechanism-driven theory beyond curve fitting.

  • Students: Learn both domains (time and frequency); demand mechanism for every formula; participate in open replications.

7) Success criteria and milestones (how we measure progress)

  • 12 months

    • White papers detailing the five most discriminating experiments; open-source simulation toolkits with dual-domain solvers; curriculum pilot modules.

  • 24–36 months

    • First empirical discriminations (e.g., trajectory reconstructions, AB phase-mapping, time-resolved “forbidden” emissions); initial finite-structure fits to g-factor trends.

  • 60 months

    • Cohesive finite-structure electrodynamics reproducing atomic spectra and magnetic phenomena without renormalization patches; education adoption at scale.

8) Clarifications (what NQT is—and is not)

  • NQT keeps quantum theory’s predictive success but sheds mystifying ontology; it is a reinterpretation with added structure, not a rejection of the math.

  • It does not posit superluminal effects, hidden variables as dogma, or anti-mathematical attitudes; it insists that every symbol earn a physical meaning.

  • Nonlocality debates dissolve when correlations are traced to shared modes and boundary histories; uncertainty is a Fourier statement, not a metaphysical fog.

  • “Vacuum energies” as absolutes are not observables; spectral differences and response functions are.

9) Closing pledge

  • We will not trade clarity for fashion, nor mechanism for mystique. We will model what is—continuous fields, finite structures, conserved flows—and let discreteness emerge where it must: from resonance in bounded systems.

  • The aim is simple and audacious: reunite quantum success with physical intelligibility, so physics can once again be both precise and understandable.

Summary of key points

  • NQT restores realism, locality, and causality by treating quanta as extended field modes; discreteness arises from boundaries, not axioms.

  • Wavefunctions represent spectra; measurement redefines boundaries; entanglement is correlation via shared modes.

  • Finite structure replaces point idealizations and their infinities; only spectral differences are observable.

  • A concrete experimental program can discriminate NQT’s mechanisms without sacrificing predictive power.

  • Education must pivot from mystique to mechanism, from slogans to definitions, and from axioms to boundaries.
