This work proposes that inertia, as posited in Newton's First Law, is not an intrinsic property of bodies but the macroscopic manifestation of a relational process grounded in the information-theoretic structure of the quantum vacuum. Drawing on standard physical results — Lorentz dilation, the Mandelstam–Tamm bound, and Maxwell's vacuum expression — the central thesis is the following: the energy–momentum projection of the kinematic decrease in the rate at which the internal phase of a moving quantum system evolves, read by an external observer as electromagnetic interaction with the vacuum, is itself read by that observer as inertia. The argument is framed within the geometry of Quantum Fisher Information and positioned as a natural extension, within quantum information theory, of Mach's relational mechanics programme and the relationalist tradition in contemporary philosophy of physics (notably the Relational Quantum Mechanics of Carlo Rovelli and the Machian programme of Julian Barbour). The work is explicitly framed as a conceptual reinterpretation rather than as a new predictive model: it modifies no equation but offers an ontological rereading of inertia as a relational phenomenon already encoded in the Heisenberg uncertainty principle.
