Black hole, illustration. A black hole is formed when the core of a star collapses under its own weight. This increases its gravitational field to the point where, beyond a boundary known as the event horizon, nothing, not even light, can escape. Only sufficiently massive stars form black holes, doing so when they have used up the fuel that sustained their nuclear explosions. | |
