説明
A black hole is a region of spacetime where gravity prevents anything, including light, from escaping. 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 a mathematically defined surface called an event horizon that marks the point of no return. It is called quot;blackquot; because it absorbs all the light that hits the horizon, reflecting nothing. In space, there are numerous black holes. They are really mysterous. Let39;s take a mystery tour to these blackholes.
