This paper proposes a new conceptual foundation for mass, inertia, charge, and the stability of matter, grounded in a dual domain ontology where spacetime emerges from a timeless Quantum Domain (QD) of pure stochasticity. Quanta are coherent probability wave patterns of stochastic tunneling. Mass is not an intrinsic property but a measure of entanglement: a single quantum with no entanglement (the photon) is massless; weak global entanglement gives the electron its small mass; internal peer entanglement makes quarks heavier; deep three‑dimensional entanglement among three quarks gives the proton and neutron their large masses. The tunneling angle θ, previously introduced to unify relativity and quantum mechanics, is reinterpreted as the bias of stochasticity: at rest θ = 90° (full isotropy), in motion θ decreases, and the Lorentz factor γ = 1/(sin θ). The speed limit c corresponds to θ = 0° (no stochasticity left). This paper explains why three quarks form stable baryons (0D: confined, 1D: metastable mesons, 3D: stable baryons), offers a topological interpretation of electric charge, and suggests testable hints including temperature dilation, coherence increase with speed, and gravity‑induced decoherence.
