Attempt free quiz on Black Hole

A black hole is a region in space where gravity is so strong that nothing, not even light, can escape from it. Black holes are formed when massive stars collapse under their own gravity at the end of their life cycles. The boundary around a black hole, called the event horizon, marks the point beyond which nothing can return. At the center lies a singularity, a point of infinite density where the laws of physics as we know them break down. Black holes come in different sizes, from stellar-mass black holes, formed from single stars, to supermassive black holes, which reside at the centers of galaxies and contain millions or billions of times the mass of the Sun. Despite being invisible, black holes can be detected by observing their effects on nearby stars, gas, and light. Studying black holes helps scientists understand gravity, space-time, and the evolution of the universe.
