Beyond Quantum Indeterminacy: Kinematic Foundations of Planck's Constant and Photon Co-Dimensioning in the TBU Framework

This paper formalizes the Time Bubble Universe (TBU) framework to provide a causal and ontological explanation for Planck's constant h, moving beyond its role as a mere "empirical adjustment factor" in standard physics. We demonstrate that real space constitutes an inert and absolute medium (the 'sea'), within which the temporal bubble expands at the limiting speed c. The crust of the bubble represents the advancing spherical boundary and the plane of present experience. In this context, c and h emerge as twin pillars of space-time: c sets the continuous expansion velocity of the spherical reference frame ($300,000\text{ km/s}$), while h represents the minimal indivisible texture and granularity of space-time—the elementary action quantum and minimum space-time unit, coinciding with the actual physical size of a photon. We demonstrate why this effect dominates in the microcosm while remaining smooth in the macrocosm, and refute the non-local interpretation of quantum entanglement experiments (Bell/Aspect).
