Black Star

A black star, or 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 exhausts its fuel and collapses under its own gravity. Black holes have a boundary called the event horizon, beyond which escape is impossible. They are not cosmic vacuum cleaners but are incredibly dense objects that influence nearby matter and light. Black holes are key to understanding the universe's structure and evolution, and their study has advanced knowledge of physics, especially gravity and spacetime.
