The Initial Spark: Macro–Big Bangs and Quantum–Cosmic Origins

We refine the Initial Spark in the two-component Time Field Model (TFM) as a singularity-free, quantum-gravitational nucleation event that triggers a macro–Big Bang (the “Spark”) outside our observable domain. This drives inflation-like ex pansion in distinct cosmic regions, potentially leaving multiverse-like bubble collisions as observational imprints. Building on wave-based quantum gravity, cosmic inflation, and high-frequency gravitational-wave phenomenology, TFM unifies these phenomena under a single two-field formalism. Observational probes include CMB V-modes, bubble collisions, and ultra-high-frequency gravitational waves (f > 109 Hz) accessible to next-generation detectors.
