Query: Quasinormal modes and horizon area quantisation in Loop Quantum Gravity   It is argued that the quantum of area between consecutive, high overtones
quasinormal modes of a black hole horizon coincides with the area gap predicted
by Loop Quantum Gravity, as long as the horizon is isolated and the
Barbero-Immirzi parameter is $\gamma \approx \sqrt{3}/6$, in agreement with the
value derived from the Bekenstein-Hawking horizon entropy.
