How AI Measures the Mass of Black Holes in Astro Physics [paradigm of scientific discovery]

Black holes, invisible yet massive, can be studied through gravitational waves generated during their mergers. These waves deform SpaceTime, offering insights into the properties of black holes, such as their mass and spin. Machine learning, particularly Bayesian inference, plays a crucial role in analyzing these signals, allowing for precise measurements of black hole parameters based on the observed data. Despite the successes of Newton's and Einstein's theories, challenges remain, particularly regarding the nonlinear dynamics of gravity, suggesting that alternatives to general relativity may yet be necessary.
