Resonant Spacetime Hypothesis 2.0

- Milestone: High-resolution power spectrum \( P(k) \) for comparison with Euclid and CMB-S4.  

3. Experimental Tests  

- Near-Term:  

- LIGO O4: Search for 35 Hz GW resonance via matched filtering (2024--2025).  

- LiteBIRD: Spiral-phase correlation analysis (2028 launch).  

- Long-Term:  

- Cosmic Atom Interferometry: Probe spacetime eigenmodes with **matter-wave sensors** (e.g., AION, MAGIS).  

Broader Implications  

RSH redefines cosmology as a deterministic, geometric process, with implications for:  

- Quantum Foundations: Spacetime as a coherent quantum resonator.  

- Philosophy of Science: Replaces probabilistic multiverses with a single, mathematically necessary universe.
