Comparative Analysis Between John Onimisi Obidi’s Theory of Entropicity (ToE) and Waldemar Marek Feldt’s FELDT–HIGGS Universal Bridge (F–HUB) Theory: From Information Fields to Entropic Dynamics: Evaluating Competing Foundations for a Post-Einsteinian Physics in Our Understanding of Nature and Reality

Einstein revealed that the constancy of light defines the architecture of spacetime. In our century, two successors to that vision—John Onimisi Obidi’s Theory of Entropicity (ToE) and Waldemar Marek Feldt’s FELDT–HIGGS Universal Bridge (F–HUB)—push this frontier deeper, each seeking to uncover what light itself is truly made of. Where relativity enshrined 𝑐 as a universal postulate, ToE reinterprets it as the finite rate at which entropy reconfigures reality. The universe does not merely move through spacetime; it reorganizes itself through the flow of entropy. Time dilation, length contraction, and mass increase emerge as inevitable responses of the entropic field to its own conservation. F–HUB, by contrast, reveals another facet of the cosmic code: information interacting with the Higgs field crystallizes into mass and gravity. It portrays a universe built from structured information, while ToE portrays one animated by entropy’s flux. Between them lies a bridge from structure to becoming, from the geometry of information to the dynamics of entropy—the bridge between what the universe is and how it becomes. This study compares the philosophical premises, mathematical foundations, and physical implications of both frameworks. ToE establishes entropy as the fundamental field and causal substrate of reality, reconstructing gravitation, time, and quantum behavior through the Obidi Action and Vuli‑Ndlela Integral. F–HUB formulates an informational architecture where mass and spacetime emerge from quantum information structuring via the Higgs field. Taken together, these frameworks signal a paradigm shift toward post‑Einsteinian physics grounded not in geometry, but in informational–entropic causation.
