Kühne, R. W. (2025). The Physics and Chemistry of Dirac Magnetic Monopoles. Preprints.org. doi:10.20944/preprints202506.0998.v1 (not peer-reviewed).
In this preprint, physicist Rainer W. Kühne proposes a theoretical framework in which Dirac magnetic monopoles form stable bound states analogous to hadrons, atoms, and molecules. He argues that such composite monopole structures could constitute the dominant component of cold dark matter.
Although magnetic monopoles remain hypothetical within mainstream physics, Kühne’s work is notable because it develops a structured particle and chemistry model for monopoles rather than treating them as isolated relic particles. This feature gives the proposal potential relevance to Two-Phase Cosmology, which independently predicts that dark matter consists of bound monopole systems rather than elementary particles.
Magnetic monopoles were first introduced by Paul Dirac (1931) as a theoretical extension of electromagnetism. Dirac showed that the existence of even a single magnetic charge would explain the quantization of electric charge, yielding the relation:
electric charge discreteness follows naturally if magnetic charge exists.
Despite extensive experimental searches, monopoles have not yet been detected. However, they continue to appear in:
grand unified theories (GUTs),
topological field theories,
duality-based extensions of gauge physics.
Kühne’s approach builds on this tradition but introduces additional particle structures and interactions.
Kühne introduces two fundamental monopole classes:
Hanselons (H): chromomagnetically charged fermionic monopoles
Gretelons (G): chromomagnetically neutral monopoles
These particles possess magnetic charge analogous to electric charge in ordinary matter.
He further proposes a chromomagnetic interaction mediated by hypothetical chromomagnetic gluons, paralleling quantum chromodynamics (QCD).
A central assumption is that the magnetic coupling constant is extremely large:
αM≈308\alpha_M \approx 308αM≈308
This implies:
free monopoles would have Planck-scale masses,
strong binding energies would dramatically reduce the mass of composite states.
As a result, observable monopole matter would not appear as isolated particles but as deeply bound composites.
The paper proposes several hierarchical structures:
| Structure | Analogy in Standard Physics | Description |
|---|---|---|
| Pairons | Mesons | monopole–antimonopole pairs |
| Triplons | Baryons | three-monopole bound states |
| Monopole atoms | Atoms | magnetically neutral composites |
| Monopole molecules | Molecules | higher-order bound systems |
Because binding energies are assumed to be very large, composite objects may be far lighter than their constituents.
Kühne refers to the resulting framework as a possible “chemistry of magnetic monopoles.”
The central cosmological claim is:
Magnetically neutral monopole atoms and molecules may constitute the majority of cold dark matter.
Key reasoning:
Free monopoles would be too massive to observe directly.
Strong magnetic binding produces lighter neutral composites.
These composites would:
interact weakly with electromagnetic radiation,
remain gravitationally active,
behave similarly to cold dark matter.
The paper estimates an upper mass scale of roughly ≈ 6 GeV per monopole constituent based on cosmological density constraints.
Two-Phase Cosmology predicts that dark matter consists not of elementary WIMPs or exotic fields but of bound monopole structures emerging from early cosmological symmetry conditions.
Kühne’s proposal aligns with several 2PC expectations:
| 2PC Prediction | Kühne Proposal |
|---|---|
| Dark matter is composite | Dark matter formed from monopole atoms/molecules |
| Monopoles rarely exist freely | Strong binding prevents free monopoles |
| Weak electromagnetic interaction | Magnetically neutral composites |
| Mesoscopic stability | Deeply bound states analogous to nuclear matter |
The independent emergence of bound monopole dark matter in an unrelated theoretical framework may therefore be viewed as conceptual convergence rather than derivation from 2PC.
Important distinctions remain:
Ontological scope
Kühne’s model is a particle-physics extension of gauge theory.
2PC embeds monopole formation within a broader cosmological phase structure involving embodiment and collapse dynamics.
Interaction framework
Kühne introduces new bosons (magnetic photons, chromomagnetic gluons).
2PC does not require additional force carriers beyond those implied by collapse dynamics.
Motivation
Kühne seeks symmetry between electric and magnetic sectors.
2PC derives monopole binding from cosmological phase constraints and stability conditions.
The work should be interpreted cautiously:
The paper is a preprint and not peer-reviewed.
The proposed particles and forces are speculative.
No experimental confirmation currently exists for monopoles or chromomagnetic interactions.
Nevertheless, the framework is scientifically interesting because it:
provides explicit microphysics for monopole dark matter,
generates testable mass-scale expectations,
offers a structured alternative to WIMP-based dark matter models.
If monopole-bound dark matter were confirmed observationally, several implications for 2PC would follow:
Empirical support for composite dark matter predictions.
A candidate physical substrate for non-baryonic gravitational structure.
A bridge between cosmological phase theory and particle phenomenology.
Future work could investigate whether 2PC collapse dynamics naturally favor the formation of monopole bound states similar to Kühne’s pairons and triplons.
