Browsing: Black Hole
A black hole is a region of spacetime where gravity is so intense that nothing—not even light—can escape its pull. Formed from the remnants of massive stars that have undergone gravitational collapse, black holes come in various sizes, from stellar-mass to supermassive varieties found at the centers of galaxies. They are defined by their event horizon, the boundary beyond which no information can return. While black holes themselves are invisible, their presence is inferred through their effects on nearby matter and light. Ongoing research explores their role in galaxy formation, gravitational waves, and the fundamental nature of space and time.
