The Role of the Observer in Modern Physics vs. Obidi's Theory of Entropicity (ToE)

In this piece, we briefly examine the "observer's privileged role" in modern physics, specifically in relation to John Onimisi Obidi's Theory of Entropicity (ToE). 

In the context of the Theory of Entropicity (ToE), the observer's role is specifically not privileged in defining physical reality. 

The Role of the Observer in Modern Physics vs. Obidi's Theory

• Modern Physics (Quantum Mechanics): In standard interpretations of quantum mechanics (like the Copenhagen interpretation), the act of observation (measurement) is central and can fundamentally alter or "collapse" a quantum system from a superposition of states into a single, definite outcome. This leads some to suggest a "participatory universe" where the observer is intrinsically relevant to the result.
• Obidi's Theory of Entropicity (ToE): Obidi's framework takes an almost opposite stance to observer-dependent theories. It argues that reality, including spacetime and quantum behavior, emerges from an underlying entropic field, independent of any observer. In ToE, reality is enforced by entropy, not by measurement or observer frames of reference. This position aims to restore Einstein's realist intuition (that reality exists independently of observation) to both relativity and quantum mechanics. 

Hierarchy of the Observer in Obidi's Framework

Therefore, within Obidi's ToE, there is no "hierarchy" that elevates the observer's role. Instead, the framework relegates the observer to an external, non-fundamental position. 

The concept of a "hierarchy of observers" is, however, explored in other contemporary theoretical physics proposals (e.g., in works by Elshatlawy et al.), which analyze different types of observers such as "external" and "internal" observers to formalize their roles across different physical domains. These separate theories suggest: 

• External Observers: Must adhere to relativistic causality and the no-signaling principle, limited by the speed of light.
• Internal Observers: Are inherently non-local and potentially acausal, but their consistency is maintained by a self-consistency principle. 

Obidi's work stands in contrast to approaches that make the mind or the observer primary, focusing instead on a universal, objective physical principle (entropy) as the fundamental driver of reality.
