From Inertial Partition of Charged Particles to 5D SpaceTime+: A Classical Path To Derivation Of Planck And Fine Structure Constantss

This short paper summarises the transition from the 4D–5D mass-partition framework to the curvature-based derivation of Planck’s and the fine-structure constants. It outlines how a universal inertial partition links mechanical and electromagnetic inertia, extending naturally into five-dimensional SpaceTime+ geometry. The presentation provides a concise conceptual and mathematical path connecting relativistic mass partition, curvature quantisation, and the emergence of fundamental constants without invoking statistical or quantum hypotheses.
