Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape from them. They form from the remnants of massive stars that collapse under their own gravity at the end of their life cycles. The boundary surrounding a black hole, known as the event horizon, marks the point of no return. Once an object crosses this boundary, it is inevitably pulled into the black hole. Black holes are characterized by their mass, charge, and angular momentum. The most common types are stellar-mass black holes and supermassive black holes, which exist at the centers of most galaxies, including our Milky Way. Recent observations by the Event Horizon Telescope (EHT) provided the first direct image of a black hole's event horizon in the galaxy M87, confirming theoretical predictions. Black holes are laboratories for testing the laws of physics under extreme conditions and play a crucial role in the dynamics and evolution of galaxies.
