Failure of Classical Physics (E = mc2): The Myth of Intrinsic Mass and Resolution via Mass Generated by Direction Component η

AbstractFor over 100 years, classical physics has assumed mass is an Intrinsic Mass, a constantproperty that comes from within matter itself. We demonstrate that this assumption failsbut, whereas mass actually depends on its external physical behavior. To describe thisbehavior, we present Regime Science, in which all structures are governed by a singleAffine Extended Field:AEF =n∑︂i=1(η + ∆i) (1)where η is the tendency term and ∆ is the deviation term. This framework reveals thatmass is not an intrinsic constant but a regime-dependent variable determined by alignmentwith η.
