Ontological Note: Frequency as Foundation. In this framework, frequency is the foundational physical quantity. All structure—spatial wavelength, energy, mass, charge, and even motion—arises from the modulation of frequency across a curved geometric manifold. The expression v = fλ is not a definition of velocity but a structural relation: frequency acts on space to create wavelength, and their combination gives rise to velocity. Thus, space itself becomes a consequence of frequency projection, and all physical quantities follow from this single causal root.
