Gravitational Wave Signatures of Informational Torsion: Predictions for LIGO, Virgo, KAGRA, and LISA

This paper explores the observational consequences of informational torsion, a form of spacetime torsion that emerges from extreme informational compression near black hole horizons within the framework of Informational Geometry. We propose that when the local informational density exceeds a critical threshold, the underlying informational substrate develops a torsional response. This torsional deformation modifies the near-horizon geometry and the propagation of perturbations, leading to potentially observable effects in the ringdown phase of binary black hole mergers. The main predicted signatures are: - Small shifts in the frequencies and damping times of quasi-normal modes - Excitation of additional torsional modes - Late-time gravitational wave echoes due to partial reflection at a torsional boundary layer We provide order-of-magnitude estimates for these effects and discuss their detectability with current (LIGO/Virgo/KAGRA) and future gravitational wave observatories (Einstein Telescope, Cosmic Explorer, and LISA). The framework is phenomenological but falsifiable, and offers a concrete link between informational approaches to gravity and upcoming observational data.
