Ten Systemic Errors of Quantum Theory
I. The Point-Particle Assumption — Repeating the Mistakes of Ancient Greece
Ancient Greek atomists regarded atoms as indivisible, structureless fundamental units. History has repeatedly proven this wrong: atoms have structure, elements have structure, atomic nuclei have structure. Every time humanity has declared it found the "ultimate, indivisible fundamental unit," the next generation of physicists has opened it up to reveal internal structure. Yet, when twentieth-century physics discovered a new layer of "elementary particles," it once again unquestioningly assigned them the identity of "structureless, infinitely small" point particles. This is not a cautious judgment based on physical facts, but a metaphysical presupposition that directly contradicts all historical lessons.
The consequences of the point-particle assumption are catastrophic: divergent self-energy, divergent vacuum energy, wave-particle duality, superluminal entanglement—a series of so-called "quantum singularities" whose roots can all be traced back to this unreasonable starting point. It is logically absurd for an infinitely small point to simultaneously carry finite mass, charge, and magnetic moment while generating a field that permeates all space. Restoring a finite size to particles (on the order of the Compton wavelength) is the first step toward resolving these pseudo-paradoxes.
II. Spin — The Substitution of Physical Reality with Abstract Symbols
The value of electron spin was mistaken from the very beginning. The physical spin angular momentum should be 1ℏ , yet pioneers mistakenly took 1/2 as an intrinsic quantum number. Subsequently, spin was stripped of its identity as angular momentum, with claims that it "has no classical counterpart" and is a purely quantum property. Paradoxically, however, spin still couples with orbital angular momentum, still generates magnetic moments, and still obeys angular momentum addition rules—precisely demonstrating that it is physical angular momentum, representing the real rotation of the particle-field system.
The erroneous methodology here is typical: first abstract the physical concept, then declare that the abstracted concept is no longer physical, while retaining all its connections to other physical quantities. This is a conceptual sleight of hand—mistaking manifestations for ontology, and mathematical labels for physical reality.
III. The Absolutization of Fermion Classification and Spin Assignment
Standard quantum theory assigns the identical spin value of 1/2 to all elementary fermions, elevating the classification of bosons and fermions into an absolute principle. Yet electrons, muons, tau leptons, and various quarks differ in mass by orders of magnitude, and their g-factors vary drastically (electron ≈2 , proton ≈5.6 , neutron ≈−3.8 ). On what basis, then, is their "intrinsic spin" exactly the same? A unified abstract quantum number obscures the real differences in the internal magnetic structures of particles, using a single label to cover up rich physical content. Classification should serve understanding, not replace it.
IV. The Neglect of the Ontological Status of Fields
Every particle is accompanied by real physical fields—electromagnetic fields, gravitational fields. These fields truly exist, possessing energy, momentum, and angular momentum; they cannot be剥离 (stripped) from the particle. However, standard quantum mechanics treats particles as isolated mathematical objects, demoting fields to mere "media of interaction" or "quantized operators," thereby neglecting the status of fields as material entities.
A dual ontology of particle-field (or even a field-only ontology) presents a picture far closer to physical reality. Once the finite size of particles is restored, their fields genuinely extend and overlap in space. Many so-called "quantum singularities"—including entanglement, tunneling, and interference—then acquire natural physical explanations.
V. The Interpretation Problem — Confusing Mathematics with Physics
The Schrödinger equation is a field equation with clear physical meaning, describing the distribution and evolution of the particle's accompanying field throughout space. However, mainstream interpretations downgrade the wave function to a "probability amplitude," replacing the equation's physical content with epistemological probabilistic statements, transforming an equation about physical reality into a declaration about "what we can know."
The fundamental error here lies in ignoring the distinction between mathematical formalism and physical reality, directly ontologizing mathematical representations, and equating mathematical properties (such as linear superposition and eigenvalues of Hermitian operators) with physical properties without inquiring into the underlying physical mechanisms. Mathematics is the language for describing physics, not physics itself.
VI. The Introduction of Numerous Unnecessary Principles
To maintain internal consistency, standard quantum theory has piled up numerous principled assumptions: the Correspondence Principle, used to bridge a rupture between classical and quantum realms that should not exist in the first place; the Pauli Exclusion Principle, which can actually be understood through the spatial overlap and magnetic interactions of real particle fields; the Uncertainty Principle, which elevates the inherent limitations of global approximate equations into fundamental laws of nature; and Wavefunction Collapse, artificially introduced to resolve logical difficulties arising from the probabilistic interpretation of the wave function.
These "principles" are not fundamental decrees of nature but logical patches for the point-particle assumption and probabilistic interpretation. A theory requiring an ever-increasing number of ad hoc hypotheses to maintain self-consistency is itself a signal that the theory has fundamental problems.
VII. Quantum Entanglement — Mystifying Ordinary Correlations
Experiments such as Bell tests, HOM interference, and SPDC demonstrate long-range correlations of fields, which are natural properties of global field modes. However, standard interpretation packages these as "superluminal non-local correlations," claiming that entanglement is "quantum magic" inexplicable by any classical picture.
Once the finite size of particles and the ontological status of real fields are restored, entanglement is simply the natural manifestation of global field correlations—no superluminality, no non-locality, no magic. Packaging ordinary physical correlations as incomprehensible "quantum resources" is a typical product of the theory's self-mystification.
VIII. Historical Displacement — The True Founders Marginalized
Historically, the concept of matter waves occupies a central, foundational position in quantum theory. It was de Broglie who proposed the matter-wave hypothesis, and Schrödinger who established the wave equation based on it—this constitutes the cornerstone of the entire mathematical framework of quantum mechanics. Without matter waves, there is no wave function; without the Schrödinger equation, quantum mechanics lacks a computable core. In terms of fundamental and enduring contribution, de Broglie and Schrödinger are the pioneers who made the greatest contributions to quantum theory.
Yet history has undergone a strange displacement. Both de Broglie and Schrödinger were deeply dissatisfied with the Copenhagen interpretation and insisted that the wave function describes physical reality rather than probabilistic knowledge. Schrödinger's proposal of "Schrödinger's Cat" was precisely intended to satirize the absurdity of the Copenhagen interpretation. However, in the game of academic power, the Copenhagen interpretation became orthodoxy. Bohr and Heisenberg were enshrined as the "gurus" of quantum theory, while the truly foundational contributors were pushed to the margins, portrayed as outdated figures who "did not understand the theory they created." This is not the natural selection of scientific history, but a distortion of scientific truth by academic politics.
IX. Direct Betrayal of the Scientific Spirit
The soul of science lies in questioning, doubting, and the relentless exploration of physical reality. However, under the dominance of the Copenhagen interpretation, quantum theory has effectively moved toward mysticism—not only failing to answer fundamental questions but also forbidding them from being asked. Mantras such as "Do not ask where the electron was before measurement" and "Do not try to understand quantum mechanics, just calculate" are not scientific attitudes but declarations of dogmatism.
When a physical theory tells you "do not inquire into physical reality," when it treats "incomprehensibility" as profundity and "giving up inquiry" as maturity, it has already betrayed the essence of the scientific spirit. Science has never acknowledged domains beyond inquiry, nor has it ever accepted incomprehensibility as an endpoint. From Galileo to Newton, from Faraday to Einstein, every major advance in physics stemmed from questioning existing frameworks and maintaining faith in physical reality. The mystification of quantum theory is not scientific progress, but a regression of the scientific spirit.
X. Mystification — The Convergence of All Errors
The nine errors above ultimately converge into one overarching tendency: mystification. Instead of reflecting on the assumptions themselves when paradoxes arise from point particles, nature is declared essentially incomprehensible. Instead of investigating the physical origin of spin, it is declared to "have no classical counterpart." Instead of seeking physical mechanisms for the measurement problem, "consciousness-induced collapse" is introduced. Instead of facing fundamental physical inquiries, questioning is forbidden.
The mystification of quantum mechanics is not the result of scientific discovery, but the logical consequence of erroneous assumptions. Just as superstition emphasizes "sincerity brings efficacy" to refuse verification, mainstream quantum theory essentially uses "the quantum world is incomprehensible" as an excuse to reject inquiry into physical reality. All these errors—from the point particle to the abstraction of spin, from neglecting fields to piling up principles, from marginalizing true founders to forbidding fundamental questions—form a complete logical chain:
Erroneous Assumptions → Conceptual Substitution → Piling of Principles → Distortion of History → Betrayal of Spirit → Comprehensive Mystification.
The first step to breaking this chain is to return to the most pristine belief of physics: Nature is comprehensible, physical reality exists, and all fundamental questions deserve to be asked.
