Black Hole Physics

Black Hole Physics studies some of the most extreme objects predicted by general relativity—regions of spacetime where gravity is so strong that nothing, not even light, can escape. Black holes form from the gravitational collapse of massive stars or through mergers of compact objects. Their defining feature is the event horizon, which marks the boundary beyond which information cannot return. Black hole physics explores properties such as mass, spin, and charge, as well as phenomena like accretion disks and relativistic jets. Quantum aspects, including Hawking radiation and black hole entropy, connect gravitation with thermodynamics and quantum theory. Observational advances, including gravitational wave detections and horizon-scale imaging, have transformed black holes from theoretical constructs into observable astrophysical objects. Black hole physics provides crucial insights into spacetime structure, gravity under extreme conditions, and the limits of known physical laws.
