Webb10 apr. 2024 · The boundary around a black hole, called the event horizon, marks a critical point of no return. Past this threshold, the gravitational pull becomes so powerful that even light cannot escape it. Since light cannot disseminate any information from within the event horizon, there is a shroud of mystery surrounding what occurs or what is present inside a … how to say walker in spanishA black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
