TMD: The Triadic Spectrum of the Event Horizon

This work introduces the triadic spectrum of the event horizon, an experimental prediction of the TMD framework. According to TMD, discrete resonant modes of the triadic network must arise just above the event horizon, where the update operator approaches the computability boundary. These modes are determined by the spectral structure of the operator, and their frequencies correspond to the critical values at which the network transitions between convergent and non‑convergent behavior. The triadic spectrum is a measurable signature: if TMD is correct, these discrete peaks should appear in gravitational‑wave observatories (LIGO, Virgo, KAGRA, LISA), in time‑resolved measurements of microscopic collapse events, and in ultra‑sensitive photon detectors (SNSPD). The work contains no cosmological interpretation; it focuses exclusively on experimentally testable manifestations of triadic resonances. This study builds on the mathematical structure of the Riemann Boundary of Computability and shows how its spectral features translate into observable physical signals.
