Causal Excitation Transfer and Persistent Mass Excitations

This paper proposes a speculative microscopic interpretation of light and matter within an Evolution-lattice framework. The central postulate is that a photon need not be represented as a material object physically transported through a pre-existing spatial medium. Instead, a source initiates a minimal excitation that is successively instantiated at causally connected Evolution nodes. What propagates between nodes is causal excitation/information, while the detected light is the local excitation produced at the receiving node. Massive excitations are postulated to be structurally more complex and persistent than the minimal photon excitation; consequently, they are not assumed to propagate by the same elementary node-to-node transfer mechanism. Displacement and acceleration of a massive excitation require directional exchange of energy-momentum.The paper further proposes a tentative interpretation of the double-slit experiment. With two open slits, the source excitation may establish coherent causal amplitudes associated with both allowed channels. These amplitudes are not interpreted as a material photon splitting into two pieces. Rather, they represent components of the Evolution state whose coherentcombination at a detector produces the observed interference probability. A which-path measurement is interpreted as an interaction that destroys the phase relation between the channels, thereby removing the interference term. The paper explicitly distinguishes this proposed ontology from established quantum mechanics: reproducing the Born rule and the observed interference pattern requires a future microscopic Evolution-lattice dynamical equation, not merely the postulation of a wavefunction. The framework is therefore presented as a research hypothesis with explicit mathematical targets and falsifiability requirements.
