The Theory of the Harmonicity of the Field of Light is an axiomatic theory that is based on two fundamental hypotheses and the selection of Projective Space as the Geometrical Space of choice. In this article we shall present its first fundamental hypothesis, in reality a slightly modified version of Special RelativityTheory?s (SRT) second fundamental hypothesis, as well as the resulting description of the Physical events. We require that description to be performed by a localized Observer who first measures and then formulates an opinion about the events, and not by an omni-present ethereal being who does so through pondering and insight. Our requirement stems from the acceptance of Werner Heisenberg?s and the School of Copenhagen?s Natural Philosophy. As a direct result, we conclude that all our observations and measurements of the physical entities, always refer not to their present state but rather to a previous one, a conclusion eerily evocative of the ?shadows? paradigm in Plato?s cave. Furthermore, we shall briefly present certain consequences of this theory such as a different approach to relativistic momentum and the quantum superposition of states (Schrodinger?s cat) as well as a possible explanation for the existence of Dark Matter.
