Black Hole
A black hole is a region in space where gravity is so intense that nothing, not even light, can escape its pull. It forms when a massive star collapses under its own gravity at the end of its life cycle, compressing all its mass into an extremely dense point called a singularity, surrounded by a boundary known as the event horizon. Beyond this horizon, the escape velocity exceeds the speed of light, making the black hole invisible to direct observation. Black holes can vary in size—from stellar-mass black holes formed by dying stars to supermassive ones found at the centers of galaxies—and play a crucial role in shaping cosmic evolution through their strong gravitational influence on surrounding matter and radiation.
The following are all physics articles on the topic of black holes. Each article provides an in-depth yet accessible discussion on this topic, offering clear explanations alongside detailed analyses.

Interior of Black Hole
Black holes sit at the edges of both our universe and our scientific understanding. They are among the strangest objects ever predicted by physics—regions where gravity pulls so strongly that nothing, not even light, can…

Detection of Black Hole
Black holes, once regarded as rare curiosities of physics, are now understood to be widespread features of the universe, with their frequency depending on their type and size. Stellar-mass black holes, the remnants of massive…
