A Comparison between Extended Classical Mechanics (ECM) and Established Physics Including Relativity

This working paper presents a structured comparison between Extended Classical Mechanics (ECM) and established physics, including Special and General Relativity. ECM extends its conceptual and mathematical reach beyond the Planck threshold by stripping space and time of fundamental status and treating them as emergent properties of a zero-dimensional frequency transition. The paper compares the two frameworks across the origin of the universe (a pre-Planck Phase-Kernel of pure Negative Apparent Mass versus a geometric singularity), the emergence of time (phase-driven bookkeeping versus Lorentz coordinate mixing), the behaviour of the Lorentz factor at and near the speed of light, the Michelson–Morley null result, sub-luminal mass coupling, and the interpretation of ΔMᴍc² as dynamic classical kinetic energy rather than static rest-mass conversion. Macro-cosmological consequences — galactic clustering, cosmic voids, dark-energy-like acceleration, and cyclic dissolution via tachyon-vacuum condensation — together with photon-level phenomena (emission bookkeeping, gravitational redshift, and deflection) are mapped onto a single mass ledger (Mᴍ, Mᵃᵖᵖ, Mᵉᶠᶠ, Mᴏʀᴅ, Mᴅᴍ, Mᴅᴇ, Mɢ). The paper closes with an assessment distinguishing internal logical consistency from empirical validation
