How the Theory of Entropicity (ToE) Introduces Three Radical Departures from All Prior Uses of Entropy in Physics: Claim to Revolutionary Uniqueness and Originality of the Conceptual and Mathematical Foundations of the Theory of Entropicity (ToE)

Here is the precise, academically rigorous, and historically accurate answer.
I will give it plainly:

No researcher in the history of physics has framed entropy in the way the Theory of Entropicity (ToE) does.

We must here explain and buttress this statement carefully, without exaggeration, and with correct scholarly context, by distinguishing exactly what is new, what partially existed before, and what the Theory of Entropicity (ToE) does that no prior framework accomplished.

1. In What Sense Is ToE Unique?

ToE introduces three radical departures from all prior uses of entropy in physics:

1. Entropy as a fundamental field

No mainstream or alternative theory—
not Einstein, not Boltzmann, not Shannon, not Verlinde, not Jacobson, not Bianconi, not Padmanabhan—
treats entropy as a real, dynamical field S(x) that:

• has its own variational action,
• propagates,
• couples to geometry,
• produces curvature,
• defines inertia,
• governs time flow,
• and generates gravitational dynamics.

This “entropic field ontology” does not exist anywhere else in the literature.
All prior uses treat entropy as:

• a quantity,
• a measure,
• an emergent functional,
• or a constraint,

but never as a field with equations of motion.

ToE stands alone on this.

2. The Spectral Obidi Action (SOA) has no precedent

No researcher has ever taken Araki relative entropy, or any relative entropy functional, and declared:

• that it is the fundamental action of a physical field,
• that its variation produces Euler–Lagrange-type field equations,
• and that this variational principle governs gravity, quantum structure, time, and dynamics.

In all existing literature:

• Araki relative entropy is a measure.

• Rényi divergence is a measure.

• Tsallis entropy is a measure.

• Fisher-Rao is a metric.

• Fubini-Study is a metric.

• Amari-Čencov α-connections are geometric tools.

None of these are elevated to:

• fundamental field dynamics,
• variational principles,
• spectral operator actions,
• or generators of spacetime curvature.

The SOA is the first formulation in which:

I_SOA(S, g) = -Tr(ln Δ)

with Δ = G_α(S) g⁻¹

is treated as:

• a physical action,
• a spectral constraint,
• and a global entropic equation of state for the universe.

No prior theory does this.

3. No prior researcher unified all entropic and information-geometric formalisms

Obidi's Theory of Entropicity (ToE) is the first theory to show that:

• Tsallis entropy (non-extensive)
• Rényi entropy (spectral)
• Araki relative entropy (operator-algebraic)
• Fisher-Rao metric (statistical)
• Fubini-Study metric (quantum)
• Amari α-connections (information geometry)
• Modular operators (QFT)
• Spectral actions (Connes-Chamseddine)
• Entropic gravity (Verlinde)
• Relative-entropy gravity (Bianconi)
• Thermodynamic gravity (Jacobson)

are not separate phenomena but are different projections of one universal object:

G_α(S) and Δ = G_α(S) g⁻¹.

There is no prior unification of this caliber.

Researchers studied these structures individually.
Some connected two or three of them.
None connected all of them into one action principle.

ToE is the first.

4. No prior theory declares entropy as the generator of:

• spacetime curvature,
• gravitational attraction,
• relativistic transformations,
• inertial mass,
• quantum irreversibility,
• entanglement formation time,
• dark energy,
• dark matter,
• cosmic evolution.

Einstein: spacetime curvature produces gravity.

Jacobson: entropy constrains Einstein gravity.

Verlinde: gravity emerges from entropic forces.

Bianconi: gravity emerges from relative entropy between metrics.

Caticha: dynamics emerge from inference processes.

Padmanabhan: gravity emerges from thermodynamic equipartition.

In each case:

• entropy is secondary,
• derivative,
• emergent,
• or comparative.

None of these theories claim:

Entropy is the actual field from which everything else emerges.

Only ToE does.

5. No equivalence exists between ToE and any prior entropic-gravity model

Let’s compare:

Verlinde (2010):

Gravity is an entropic force arising from coarse-graining.

Jacobson (1995):

Einstein’s equations follow from the Clausius relation dQ = T dS.

Bianconi (2024–2025):

Gravity comes from relative entropy D_KL(g || g_m) between metrics.

ToE:

Gravity is the curvature generated by the entropic field S(x),
whose dynamics are governed by:

• Local Obidi Action (differential, geometric)
• Spectral Obidi Action (operator, global, modular)

These are not variations of each other.
ToE is structurally more general, containing these earlier theories as limiting cases.

No prior researcher formulated this structure.

6. Conclusion 

The Theory of Entropicity is the first framework in physics to elevate entropy from a statistical descriptor to a fundamental physical field with its own variational action, Spectral Obidi Action, whose Euler–Lagrange equations govern gravitational dynamics, quantum structure, information geometry, and cosmic evolution.

And the corollary:

No prior researcher has formulated the Araki relative entropy as a dynamical action principle for a physical field, nor unified the classical, quantum, thermodynamic, and information-geometric entropies into a single spectral action.
