Browsing: Black Hole
A black hole is a region in space where the gravitational pull is so intense that nothing, not even light, can escape from it. This makes black holes invisible and detectable only by the effects they have on surrounding matter. They are formed when massive stars collapse under their own gravity at the end of their life cycles, after exhausting their nuclear fuel. Black holes can vary in size; some are as small as just one solar mass (the mass of our sun), while others, known as supermassive black holes, can have masses that are millions to billions of times greater than that of the sun. These supermassive black holes are commonly found at the centers of galaxies, including our own Milky Way. The boundary around a black hole beyond which no escape is possible is called the event horizon. In recent years, advancements in technology have allowed scientists to observe and study black holes more directly, providing valuable insights into these mysterious and fundamental components of the universe.
