Helix Light Vortex Theory (HLV)
(Marcel Krüger born 18.07.84, 2025-07-12) Marcel Krüger
The Helix-Light-Vortex (HLV) theory presents a comprehensive physical model where space, time, matter, and information emerge from a unified geometric and informational foundation. The theory is built on a small set of axioms: a discrete dodecahedral vacuum lattice, a complex scalar field Ψ, a universal information field Φ, and a dynamic spiral time ψ(t).
At its core, the HLV framework postulates that particles are not fundamental points but structured, helical energy states. These exist in three forms: convergent (+1, matter), divergent (-1, antimatter), and inert (0, dark matter). The dynamics of the universe are governed by a unified Lagrangian that includes terms for the matter field, the information field, their interaction, and a crucial coupling to the metric responsible for phenomena like the muon g-2 anomaly.
From this foundation, physical properties emerge naturally. Mass is the energy of standing waves within the vacuum lattice, spin arises from the helical topology of the field configurations, and electric charge is a conserved Noether current derived from the model's U(1) symmetry. This framework offers quantitative, testable predictions and seeks to bridge the gap beyond the Standard Model.
Helix Light Vortex Theory (HLV)
(Marcel Krüger born 18.07.84, 2025-07-12) Marcel Krüger
This paper proposes a geometric origin for the hadronic mass spectrum, spin, and electric charge based on the Helix-Light-Vortex (HLV) theory. In this framework, hadrons are not composed of confined quarks but emerge as stable, quantized standing-wave resonances of a fundamental scalar field Ψ, confined within a discretized dodecahedral vacuum lattice.
The HLV theory provides an alternative: hadrons arise as resonance states of a scalar field Ψ in a discrete geometric background. The vacuum is modeled as a tessellation of regular dodecahedral cells, and the resulting hadron mass spectrum becomes a function of integer multiples n. Using n=7 for the nucleon mass, this model accurately predicts the masses of other fundamental hadrons, such as the π⁰-Meson (for n=1) and the η-Meson (for n=4), with high precision.
The scalar field Lagrangian exhibits a global U(1) symmetry, which is identified with electric charge conservation. Spin emerges from the topology of the field configuration, while the conserved charge is derived from the Noether current. The HLV theory provides a unified, geometric explanation for hadron mass, spin, and charge, based on standing wave modes in a discrete dodecahedral vacuum.
Helix Light Vortex Theory (HLV)
(Marcel Krüger born 18.07.84, 2025-07-12) Marcel Krüger
This paper presents a direct theoretical derivation of the muon's anomalous magnetic moment from the foundational principles of the Helix-Light-Vortex (HLV) theory. We demonstrate that the experimentally observed deviation from the Standard Model naturally emerges as a geometric correction from the interaction between the muon's resonant field and a retrocausal information field within a spiral-modulated spacetime. The resulting value, ( \Delta a_\mu^{\text{HLV}} \approx 2.48 \times 10^{-9} ), is derived without postulating new particles and is in precise agreement with the latest Fermilab g-2 measurements, offering a new, testable explanation for one of physics' most significant anomalies.
Hunting and bush mango harvesting
(University of dschang FASA, 2015-01) Charles Le Bon NGALAGOU NGALAGO
Dans le cadre de la révision du plan d'aménagement de l'ufa 10040, il a été question de caractériser l'activité de collecte des mangues sauvages ( Irvingia spp) et déterminer ses rapports avec la chasse pratiquée par ses acteurs.
Il en ressort que les collecteurs sont aussi des chasseurs. Cette chasse est pratiquée sans autorisation avec des techniques illégales.
