This work presents a conceptual theoretical framework proposing that cosmological phenomena may be interpreted through homogeneous universal scale evolution, described as a gradual diminution affecting all physical systems equally. The framework is formulated using scale symmetry (conformal/Weyl transformations) and explores qualitative and mathematical implications for light propagation, time measurement, gravitational phenomena, and dark energy interpretation. Because matter, measuring devices, and physical clocks co-evolve with the same scale factor, such evolution remains locally indistinguishable, while observable effects emerge through comparisons between cosmological epochs. The objective of this work is not to introduce a finalized dynamical theory, but to provide a coherent conceptual structure suitable for further theoretical, mathematical, and phenomenological investigation.
