Black holes are regions in space where the gravitational pull is so strong that nothing, not even light, can escape from them. They are formed when massive stars exhaust their nuclear fuel and collapse under their own gravity at the end of their life cycles. The boundary surrounding a black hole is called the event horizon, beyond which events cannot affect an outside observer.
Black holes can vary in size, with stellar black holes typically having a mass several times that of the Sun, while supermassive black holes, found at the centers of galaxies, can have masses equivalent to millions or billions of Suns. There are also theoretical concepts of primordial black holes, which may have formed shortly after the Big Bang.
Black holes are key objects in astrophysics, helping to advance our understanding of gravity, spacetime, and the very nature of the universe. Their presence can be inferred through various observations, such as the behavior of nearby stars and gas, the emission of X-rays from matter falling into them, and the gravitational waves generated by their mergers.
