The Theory of Entropicity (ToE) and John L. Haller's Action-as-Entropy Equivalence Principle: Validation of the Foundations of the Theory of Entropicity (ToE)

John L. Haller’s work connects to the Theory of Entropicity (ToE) through the fundamental assertion that entropy is equal to physical action. In his paper Information Mechanics, Haller proposes that entropy is not merely a secondary statistical measure but the primary driver of physical motion. [1, 2]

Core Connections between Haller and ToE

The Theory of Entropicity (ToE), pioneered by John Onimisi Obidi, adopts and extends several of Haller's conceptual foundations: [3, 4]

• Entropy as Action: Haller put forward the unifying theory that entropy and action are equivalent ($S = A$). This is a cornerstone of ToE, which utilizes the Obidi Action to derive physical laws from the dynamics of an entropic field.
• The Bernoulli Process: Haller hypothesized that particles move via a discrete Bernoulli Process. ToE incorporates this into its "No-Rush Theorem," which posits that physical interactions are not instantaneous but are discrete reconfigurations of the entropic field that require finite time.
• Information-Geometric Bridge: Haller used information-theoretic methods to derive his results. ToE formalizes this by using Information Geometry (e.g., Fisher-Rao and Fubini-Study metrics) to treat physical curvature as a manifestation of information flow.
• Emergent Relativity: Haller noted that while his hypothesis matched the mean values of special relativity, it suggested "new physics" in its variance. ToE follows this path by reinterpreting Einstein's postulates (like the constancy of the speed of light) as emergent consequences of a fundamental entropic rate. [2, 5, 6, 7, 8]

Comparison Table: Haller vs. Obidi (ToE)

Feature [3, 6, 9, 10, 11]	John L. Haller's Theory	John Onimisi Obidi's ToE
Primary Identity	Entropy = Action	Entropy = Fundamental Ontological Field
Medium of Reality	Discrete Bernoulli Process	Continuous Entropic Field
Causality	Statistical movement	No-Rush Theorem (Finite Interaction Time)
Relativity	Matches mean values	Derives Kinematics (Time Dilation, Length Contraction)

Haller's perspective shifted the role of entropy from a "shadow" of physical laws to the "light source" that creates them—a philosophy central to the current development of the Theory of Entropicity. [4]

In his work, notably "Action as Entropy" (2015), John L. Haller explores concepts that align with entropic theories regarding the fundamental nature of physics. 

Sciforum

Key points from Haller's work that connect with entropy-based theories of everything (ToE) include:

• Action as Entropy: Haller argues that the "action" of a particle (a fundamental quantity in quantum mechanics and classical mechanics) is equal to its entropy.
• Second Law as Fundamental: He proposes that the second law of thermodynamics is the foundational justification for the principle of least action.
• Entropy/Energy Relationship: He suggests that entropy, in natural units, is equivalent to energy times time minus the action of a particle.
• Vacuum Interaction: Haller suggests that the mutual information between a particle and the vacuum is equal to its potential energy. 
• Sciforum +1

These concepts aim to bridge quantum mechanics and thermodynamics by suggesting that fundamental actions are inherently entropic.
