Gravitational-wave astronomy has the potential to substantially advance our knowledge of the cosmos, from the most powerful astrophysical engines to the initial stages of our universe. Gravitational waves also carry information about the nature of black holes. Here we investigate the potential of gravitational-wave detectors to test a proposal by Bekenstein and Mukhanov that the area of black hole horizons is quantized in units of the Planck area. Our results indicate that this quantization could have a potentially observable effect on the classical gravitational wave signals received by detectors. In particular, we find distorted gravitational-wave "echoes" in the post-merger waveform describing the inspiral and merger of two black holes. These echoes have a specific frequency content that is characteristic of black hole horizon area quantization.

Model-agnostic search of gravitational wave echoes in LVK data
A multi-detector phase-marginalized echo search finds no statistically significant long-lived quasinormal-mode echoes in GW150914, GW231226, and GW250114, and sets 90% upper limits on their network SNR and amplitude.

Stretched Horizon Dissipation and the Fate of Echoes
A microscopic estimate shows infalling modes with frequency near the Hawking temperature suffer only moderate dissipation before reaching a stretched horizon, so gravitational wave echoes could survive.

Probing the existence of a minimal length through compact binary inspiral
A minimum length in spacetime would make black holes perfectly reflective below a cutoff frequency, imprinting the inspiral waveform via modified tidal heating.
