A **black hole** is a region of space from which nothing, not even [|light], can escape. The theory of [|general relativity] predicts that a sufficiently compact [|mass] will deform [|spacetime] to form a black hole. Around a black hole there is an undetectable surface called an [|event horizon] that marks the point of no return. It is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect [|black body] in [|thermodynamics].
