A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform. A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from. A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been. Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a. Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black. Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a. Astronomers have detected the most powerful, most distant and most perplexing collision of black holes yet using gravitational waves. Black holes are volumes of space where gravity is extreme enough to prevent the escape of even the fastest moving particles. Not even light can break free. Stellar Black Holes are created when massive stars die. They end their lives in violent supernova explosions – most of the star's matter is blown away leaving. Hawking and others sought to describe matter in and around black holes using quantum theory, but they continued to describe gravity using.
