Three quantum-inspired cores leave opposite fingerprints on the ringing of black holes

Physicists have modeled how different quantum-inspired black hole centers affect the 'ringing' of gravitational waves after a merger. By calculating quasinormal modes, researchers suggest that the internal structure of a black hole leaves a distinct signature on the gravitational waves it emits.
Why it matters
This research provides a theoretical framework for testing quantum gravity theories using future gravitational wave observations.
