The Temporal Fluid Multiverse: A Unified Framework for Causality and Observation

This paper presents the Temporal Fluid Multiverse (TFM) model, a unified theoretical framework that reinterprets time as a dynamic causal medium analogous to a fluid. Entities exist in two modes: actors, who interact with and alter the causal medium, and observers, who perceive its flow without influencing it. The model integrates established principles of relativity, thermodynamics, and quantum mechanics, particularly entropy and decoherence, to explain the directional nature of time and the emergence of parallel continua. It asserts that active reinsertion into a prior temporal state requires reconstruction of the entire causal medium, generating a new, divergent continuum. This resolves long-standing paradoxes of time travel and causality while maintaining consistency with physical law. The Temporal Fluid Multiverse characterizes observation as an informational coupling state bridging physics and perception within a coherent causal framework. The model is presented as an effective reinterpretation of known physical laws (consistent with General Relativity and quantum mechanics) and aims to describe emergent temporal behavior in regimes dominated by entropy production and decoherence.
