Black hole, illustrationのイラスト素材

Computer illustration of a black hole. A black hole is an object so compact (usually a collapsed star) that nothing can escape its gravitational pull. Not even light. The escape velocity of a black hole exceeds the speed of light. Since nothing can travel faster than this ultimate speed, black holes suck in everything including light, which makes them utterly dark and invisible. In this image, we can see a black hole, but only because it is surrounded by a superheated disc of material, an accretion disc.
