Blackhole

A black hole is an incredibly dense region in space where gravity is so strong that nothing, not even light, can escape from it. It forms when a massive star exhausts its fuel and collapses under its own gravity, compressing its core into a point called a singularity. Surrounding the singularity is the event horizon, the boundary beyond which escape is impossible. Black holes can affect nearby matter and light, creating observable effects like distorted light or star movements, but remain invisible themselves. They are fundamental in understanding the universe's structure and the behavior of gravity under extreme conditions.
