The black hole always chirps twice: Scientists find clues to decipher the shape of black holes
A team of gravitational wave researchers led by the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav) report that when two black holes collide and merge, the remnant black hole “chirps” not once, but multiple times, emitting gravitational waves—intense ripples in the fabric space and time—that reveal information about its shape. Their study has been published in Communications Physics.
