TL;DR

This paper proposes a classical, deterministic framework for explaining the Casimir effect and the fractal-like organization of zero-point electromagnetic energy around matter, using constrained, rotating photons forming quantized shells. It derives the attractive Casimir force between uncharged plates by modeling energy density as a sum of discrete, frequency-decaying layers, offering a geometric and electrodynamic explanation without relying on standard quantum field theory principles.

ABSTRACT

The zero-point radiation is an electromagnetic form of energy pervading the universe. Its existence is granted by standard quantum theories. We provide here an explanation based on deterministic classical electrodynamics, by associating to particles and nuclei a series of shells, made of constrained photons, with frequencies decaying with the distance. Such photons are part of a pre-existing background, evolving in vacuum even at zero temperature, and are captured by stable subatomic particles to form very distinctive quantized patterns. The evolving shells bring, for instance, to the creation of a fractal-type structure of electromagnetic layers around a conductive body. This property is then used to justify, both qualitatively and quantitatively, the attractive Casimir force of two metal plates. The analysis is carried out by standard arguments, except that here the surrounding zero-point energy is finite and, albeit with a very complicated appearance, very well-organized.

Motivation & Objective

• To explain the Casimir effect using classical electrodynamics and a deterministic model of zero-point radiation.
• To demonstrate how stable, quantized electromagnetic structures (fractal-like shells) form around particles due to constrained, rotating photons.
• To provide a geometric and energy-based explanation for the attractive Casimir force between uncharged metallic plates.
• To unify electromagnetic, quantum-like phenomena (e.g., Casimir, Coulomb, van der Waals) under a single framework based on spacetime geometry and electromagnetic field dynamics.
• To explore the implications of this model for non-planar geometries, such as spherical plates, despite the complexity of such configurations.

Proposed method

• Model electromagnetic fields using a modified form of classical electrodynamics coupled with Euler’s equation for ideal fluids, embedding the system in a general relativistic framework.
• Use exact solutions of the model equations to describe constrained, rotating photons forming stable, toroidal or disk-like configurations in 2D and 3D.
• Associate each stable particle with a series of concentric, frequency-decaying electromagnetic shells (fractal layers) generated by rotating photons constrained in space.
• Compute energy density as a sum of contributions from individual layers rather than a continuous integral, emphasizing discrete, quantized patterns.
• Apply the model to parallel, uncharged metallic plates by analyzing the difference in internal and external energy densities due to the layered structure of zero-point fields.
• Account for the stationary Coulomb field in charged plates by superimposing it on the time-dependent, layered field structure, enhancing the net attractive force.

Experimental results

Research questions

• RQ1 Can the Casimir effect be explained without invoking quantum field theory, using only classical electrodynamics and a deterministic model of zero-point radiation?
• RQ2 How do rotating, constrained photons give rise to stable, quantized electromagnetic structures around particles, and what is their geometric and energetic organization?
• RQ3 What is the role of spacetime geometry in stabilizing these photon-based structures and enforcing a fractal-like layering of electromagnetic energy?
• RQ4 How does the energy density difference between the region between two plates and the external region lead to a net attractive force in the uncharged case?
• RQ5 To what extent can the same framework explain other fundamental forces (e.g., Coulomb, van der Waals) as manifestations of the same underlying electromagnetic and geometric dynamics?

Key findings

• The Casimir force between uncharged, parallel metallic plates arises from a difference in energy density due to discrete, frequency-decaying electromagnetic layers, not from vacuum fluctuations in the standard quantum sense.
• The model predicts that the zero-point energy is finite and highly structured, forming a fractal-like hierarchy of shells around particles, with higher-frequency photons closer to the core.
• The energy density computation is reinterpreted as a sum over discrete layers rather than a continuous integral, which naturally leads to a net inward force when the layers are compressed between plates.
• The stationary electric field in charged plates enhances the negative pressure, increasing the net attractive force, consistent with the Coulomb law but derived from the same geometric framework.
• The model suggests that all fundamental forces (Coulomb, Casimir, van der Waals, gravity) emerge from the same set of equations combining electromagnetism and spacetime geometry via Einstein’s equation.
• Non-planar geometries (e.g., spherical plates) may lead to repulsive Casimir forces due to deformation of the electromagnetic layering, though the model acknowledges the difficulty of precise prediction without detailed knowledge of short-distance matter behavior.
