Black Hole is a black thing in the space which absorbs everything that comes in its way and if entered nothing can escape from it even light and its gravitational force is faster than light and that's why nothing can escape from it because light is the fastest thing in the universe and its gravitational force is faster than that.Black Holes are formed when the core of a massive star collapses in on itself at the end of its life.The closest Black Hole to Earth is located in the constellation Ophiuchus 1,560 light-years away called Gaia BH1 discovered in 2022 which is 10 times more massive than the Sun.
