Black holes - the absorbing objects par excellence - are no exception. When formed in a merger, black holes vibrate in a process called \"ringdown\", which leaves the gravitational-wave footprint of the event horizon. In some models of quantum gravity which attempt to solve the information-loss paradox and the singularities of General Relativity, black holes are replaced by regular, horizonless objects with a tiny effective reflectivity.
