Black holes, the most gravitationally extreme objects in the universe, emit space-time ripples called quasinormal modes when disturbed - vibrations that can be detected as gravitational waves. These signals offer critical insight into a black hole's mass and structure, but precisely modeling the rapidly fading ones has remained elusive.
