The article discusses the merging of supermassive black holes at the centers of galaxies, highlighting a long-standing issue called the "final parsec problem." This problem arises when black holes, after merging galaxies, are unable to come close enough to coalesce due to the dynamics of their orbits, potentially stalling their merging indefinitely. Recent evidence, including observations of gravitational waves, suggests that these black holes do overcome this hurdle. The gravitational waves are believed to originate from pairs of supermassive black holes
