The Halo Model of Entropy is a structural sub-model within the Energy-Flow Cosmology (EFC) framework.
It interprets galactic halos not as dark-matter halos, but as zones of entropic equilibrium — regions where outward energy flow and inward gravitational potential balance through thermodynamic tension in the spacetime grid.
In this model, gravitational stability emerges naturally from the gradient of entropy, without requiring non-baryonic matter.
The halos act as thermodynamic buffers that regulate rotational velocity, energy distribution, and large-scale coherence in galaxies and clusters.
The model suggests that:
- Dark matter effects are apparent thermodynamic artefacts of energy-flow curvature.
- Halo boundaries correspond to entropy-flow saturation zones, measurable via density and temperature gradients.
- Large-scale structure formation reflects self-organizing entropic feedback, not hidden mass.
By connecting local galactic behavior with universal thermodynamic principles, the Halo Model of Entropy provides a bridge between EFC-S (structure) and EFC-D (dynamics).
It aligns with observational patterns seen in rotation curves, lensing profiles, and the entropy–mass scaling relations of clusters.
