Ringdown Gravity: A Self-Contained Effective Gravitational Theory of the Dark Sector

Ringdown Gravity (RG) is a self-contained effective gravitational theory in which phenomenology conventionally attributed to dark matter and dark energy is encoded as a state-dependent gravitational response rather than a new dark particle.The fixed-background foundation is retai...

Ringdown Gravity: A Self-Contained Effective Gravitational Theory of the Dark Sector

Ringdown Gravity (RG) is a self-contained effective gravitational theory of the dark sector in which phenomena conventionally attributed to dark matter and dark energy arise from the response of a ringing horizon rather than from a new dark particle. The paper develops the fixed-...

Schwarzschild Ringdown as a Resonance-Information Process: A Fixed-Background Case Study of Horizon Distinguishability, Modular Relative Entropy, and Unitary Resonance Compression

This record presents a fixed-background case study in the linear axial ℓ=2\ell=2ℓ=2 sector of Schwarzschild perturbation theory. Two independent real Regge–Wheeler evolutions are combined after evolution to form a complex horizon waveform. On the finest numerical grid, the fundam...
