Black holes as a research area encompass the theoretical, observational, and computational study of regions of spacetime where gravity is so intense that no matter or radiation can escape beyond the event horizon. This field investigates black hole formation, stability, and classification (stellar-mass, intermediate-mass, and supermassive), their thermodynamics, accretion physics, jet launching, and role in galaxy evolution. It also includes tests of general relativity in the strong-field regime, gravitational-wave signatures from black hole mergers, numerical relativity simulations, and horizon-scale imaging, integrating methods from relativistic astrophysics, high-energy physics, and computational modeling.
On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of ...
