Quantum Fields as Immortal Substrate: A Field-First Ontology of Particle Actualisation, Emergent Properties, and the Nature of Physical Reality

Contemporary quantum field theory is typically introduced through the lens of particle mechanics, treating fields as mathematical auxiliaries from which particles — the 'real' objects — are derived. This paper argues for an inversion of that priority. We propose that quantum fields are the primary ontological substrate: immortal, pre-propertied, and total. Particles are not objects within fields but transient events — actualisations — that occur when a discrete set of conditions distributed across the field simultaneously converges. This framework, which we term the Field-Actualisation Model (FAM), resolves several canonical paradoxes of standard quantum mechanics — including measurement, superposition, and wavefunction collapse — by revealing them as artefacts of particle-first framing rather than genuine features of nature. We reinterpret the Schrödinger wavefunction as a condition-density map, derive its empirical predictions under this lens, show consistency with all known experimental results, and explore the implications for emergence, information, and the deep structure of physical reality.
