Gravitational Wave Propagation Speed Is Inversely Proportional to Frequency: A Quantitative Prediction Based on the Ontology of Cognitive Succession

General relativity's conclusion that gravitational waves propagate at the speed of light in vacuum without dispersion is built on the unproven ontological presupposition that spacetime is a smooth, uniform, and innate container. Based on the original Cognitive Succession Ontology as the sole foundation and taking "the essence of cognition is succession" as the unfalsifiable first principle, this paper deduces that authentic physical spacetime is not an innate container but a three-dimensional coupling network of one-dimensional successive rays, and absolute vacuum does not exist in the world. It can be necessarily deduced from the ontological level that gravitational waves, as perturbations of the spatiotemporal successive coupling network, inevitably exhibit dispersion effects; there are inherent differences in the propagation speeds of gravitational waves with different frequencies, with higher frequencies corresponding to slower propagation speeds. This paper only conducts pure ontological deduction and does not involve engineering quantification, experimental schemes, or on-site observations. If this ontological prediction holds true, it will fundamentally subvert the traditional view of spacetime and provide a priori logical basis for the ontological reconstruction of physics.
