Topological Aether, Fields, Vacuum, Dark Matter, and Dark Energy

This chapter strictly follows the GDUM three-layer hierarchical architecture, the dual-window same-origin principle, the channel-isolation red line, and the topological emergence rules. It uniformly defines the ontological levels, mathematical attributions, and physical readout mechanisms of the five core concepts—topological aether, fields, vacuum, dark matter, and dark energy—thereby completely severing classical aether, vacuum zero-point energy, medium/fluid models, and multi-component independent dark-entity models, and completing the full self-consistent closure of the theoretical system.
