Wave or Particle? Quantum Behavior of Solar System

Article January 23, 2026

Starting from Kepler's laws of planetary motion, this paper applies the real-particle theory to study the motion property and quantum behavior of the solar system. The solar system is a typical multi-body cluster (real particle) that has three motion modes of translation, rotation, and vibration. In a two-dimensional case, the earth/solar system is a two-body cluster that moves in its orbital plane and can be modeled as a rotating vibrator. The classical state function of the vibrator is an elliptic equation, and the quantum state function is a mapping of the elliptic equation to the complex plane. The state function contains the information of the cluster motion and satisfy the Schrödinger equation. The study shows that the quantum state function characterizes a time-averaged property of cluster motion, and the Schrödinger equation is a mapping algorithm from the potential function to the state function. The parameters of a planetary orbit are implicit variables of the quantum state, and the statistics of cluster motion are the reality basis of quantum mechanics.

Dark Matter and Real-Particle Field Theory

Article January 15, 2022

Based on real-particle field theory, this research demonstrates that dark matter comprises elastic electrons with a full cosmic background. In the real-particle field theory, real particles are elastic particles with both mass and volume. Real particles have three independent motion modes and two symmetrical interactions. The evolution of the real-particle field follows a set of Poisson equations. The theory shows that the electric and magnetic potentials represent electronic interactions of mass attraction and motion repulsion. The electromagnetic and dark-matter fields are essentially elastic electron fields. The laws of mechanics, gravitation, and electromagnetism of classical physics can be inferred from the real-particle field theory. In the electron field, electronic clusters are photons with the energy proportional to vibration frequency. The mechanic features of photons can be characterized by their volume, mass, and elasticity. Furthermore, the radiation of electronic clusters follows Planck’s law, which indicates that dark matter has a uniform density and no photonic current in the cosmic background. It is shown that matter essentially comprises discrete particles, and the matter field is merely a statistical convolution effect of a large number of particles. Consequently, dark matter particles contribute to the structural formation of all matter in the universe.

Outline of Real Physics

Article April 8, 2020

Real physics is an axiomatic theoretical system based on the model of elastic particles. Unlike point-like and wave-like particles, elastic particles are objects with both mass and volume, which can spin and deform. Electrons, protons, and atoms are elastic particles. Elastic particles have three motion modes of translation, rotation, and vibration. The system of elastic particles follows simple and universal laws of motion. This paper briefly reviews the core concepts, basic principles, main contents, and major achievements of real physics. It shows that the classical physical laws (laws of motion, gravitation, electromagnetism, and thermodynamics) are all conclusions drawn from the statistics of elastic particles, which reveals the irreversibility of natural processes.

Motion of Elastic Particles and Spectrum of Hydrogen Atoms

Article November 25, 2019

This article analyzes the spectral structure of hydrogen atoms according to the motion theory of elastic particles. The results demonstrate that optical radiation originates from the elastic vibration of atoms or molecules. The quantum state is the equilibrium feature of the classically statistical system, and the quantum transition is the process of conversion between different motion modes.
