Emergent Time from Causal Signal Propagation with Effective Viscoelastic Behavior of Cosmic Structures

This work proposes an interpretational framework in which time is understood as an emergent property arising from causal signal propagation. In contrast to conventional approaches that treat time as a fundamental background parameter, this framework interprets temporal structure as a consequence of finite signal propagation and causal connectivity between physical systems. Observable reality is constructed from delayed field contributions, and the present is defined as a local superposition of signals arriving from different spacetime locations. Temporal flow is reinterpreted as the continuous updating of observable states as new signals arrive. The framework preserves the mathematical structure of established theories, including General Relativity and quantum mechanics, and does not introduce modifications to spacetime geometry. Instead, it provides a physically grounded interpretation of time consistent with relativistic causality. Importantly, the approach leads to potentially testable consequences, such as propagation-induced phase dispersion and distance-dependent decoherence over cosmological scales. This work is intended as a conceptual and physical interpretation bridging causality, information propagation, and temporal structure.
