This work introduces an exploratory conceptual framework in which a variable denoted by α is interpreted as an effective emergent dimension associated with temporal becoming. Rather than postulating α as a fundamental spacetime coordinate, the proposal treats it as a phenomenological and structural construct arising from the organization of irreversible processes, temporal asymmetry, and emergent ordering across scales. No claim is made regarding experimental validation or closed mathematical formalization at this stage. The framework is intentionally incomplete and aims to clarify conceptual scope, establish authorship and priority, and provide a coherent space for future discussion, critique, and potential formal development within physics, particularly in contexts involving irreversibility, emergence, and complex systems.
