Albert Einstein and John Onimisi Obidi: Two Theories of Physics, but One Goal of Nature, the Universe, and Reality 

"Einstein and Obidi" refers to the comparison between Albert Einstein's Relativity and John Onimisi Obidi's recent "Theory of Entropicity (ToE)," which posits entropy, not spacetime, as fundamental, explaining relativity's concepts (time dilation, mass increase) as emergent properties of an entropic field, aiming to unify physics by deriving Einstein's theories from core entropic principles. Obidi's work uses the "Obidi Action" and "Master Entropic Equation (MEE) — otherwise known as the Obidi Field Equations of the Theory of Entropicity (ToE)" to describe how entropy's flow governs geometry, matter, and causality, reinterpreting relativity's core ideas as entropic inevitabilities. 

Key Concepts in Obidi's Theory of Entropicity (ToE)

• Fundamental Field: ToE proposes entropy as the primary field, with spacetime, gravity, and matter emerging from its dynamics, unlike Relativity where spacetime is primary.
• Obidi Action: A variational principle for the entropy field, analogous to Einstein-Hilbert action in General Relativity, from which the core equations are derived.
• Master Entropic Equation (MEE): Governs the evolution of entropy and its coupling with geometry and matter, similar to Einstein's field equations.
• Emergence of Relativity: ToE explains time dilation, length contraction, and mass increase as consequences of entropic capacity constraints during motion, not just observer perspectives.
• Unification Goal: Aims to unify thermodynamics, quantum mechanics, and relativity under a single entropic framework, seeing them as different manifestations of entropy. 

Einstein vs. Obidi (ToE)

• Role of Entropy: For Einstein, entropy is a statistical concept; for Obidi, it's a fundamental, generative field.
• Spacetime: In Relativity, spacetime is fundamental; in ToE, spacetime and gravity emerge from the entropic field's local variations.
• Causality: ToE views the arrow of time and causality as intrinsic to entropy's irreversible flow, rather than just a feature of spacetime. 

In essence, Obidi's ToE seeks to provide a deeper, unifying explanation for phenomena described by Einstein's Relativity, showing them as specific outcomes of universal entropic principles.
