Testing the Quantum Suppression Principle: New Constraints from Gravitational Wave Astronomy

Gravitational wave observations provide a unique testing ground for energy-dependent quantum suppression effects and potential quantum gravity corrections. The Quantum Suppression Principle (QSP) proposes that quantum mechanical effects diminish as energy increases, leading to a transition from quantum to classical behavior. We hypothesize that this suppression follows an inverse energy-squared scaling law:Q₉ ≈ (G ℏ²) / (c³ E²)suggesting that quantum effects fade with increasing energy, naturally explaining the large-scale classical behavior of gravity.To test this framework, we analyze high-frequency (≥500 Hz) gravitational wave signals from LIGO’s third observing run (O3). Using matched filtering and frequency-dependent amplitude analysis, we search for deviations from classical general relativity in the inspiral and merger phases of compact binary coalescences. If QSP effects exist, they should manifest as slight amplitude damping or phase distortions at high frequencies. In the absence of suppression effects, we establish new upper bounds on the suppression coefficient:Cₛᵤₚₚ ≤ 10⁻²²representing one of the most stringent astrophysical constraints on energy-dependent quantum suppression to date.We further explore systematic uncertainties, including detector calibration errors, waveform model uncertainties, and high-frequency noise mitigation strategies. Independent cross-validation with Virgo data confirms the robustness of these constraints. While no significant suppression was detected, future detectors such as Cosmic Explorer and LISA will provide enhanced sensitivity to probe weaker suppression effects and potential quantum gravity signatures.This study represents the first astrophysical test of the Quantum Suppression Principle, providing a framework for future gravitational wave-based constraints on quantum gravity phenomenology.
