Causal Cosmological Model_Consolidated Version (Stabilized Gravitational Field Model)

This work presents a causal cosmological model in which the fundamental entity is a gravitational energy field, whose configurations give rise to matter as a metastable stabilizing phase. Matter is not fundamental; it temporarily reduces the intrinsic instability of the field and can persist only within a local instantaneous stability bound. A central constraint governs material persistence: S = \gamma \Phi \le S_{\max}, where structural complexity and cohesion (\Phi) are amplified by relativistic effects (\gamma), and where S_{\max} represents a local, instantaneous limit rather than a cumulative capacity. Time dilation does not increase this bound; it can only delay structural failure. When the bound is exceeded, matter irreversibly transitions back toward a field-dominated regime. Within this framework, late-time cosmic acceleration emerges naturally from the progressive loss of matter-based stabilization, without invoking any fundamental dark energy or cosmological constant. The model also allows for the existence of sibling universes—distinct realizations sharing the same laws but without hierarchy. Clear falsifiability criteria are provided, making the model testable through limits on structural stability, relativistic amplification, and the necessity (or not) of a fundamental cosmological constant.
