Inside A Black Hole
Well, the gravity well of a black hole is so deep that not even light can climb out of it. According to Einstein’s General Theory of Relativity, light is the ultimate limiting factor in the Universe. Nothing – and that means nothing – can move faster than light, whose speed is 300,000 kilometres per second. The speed necessary to climb out of any given gravity well is known as that gravity well’s escape velocity, and the escape velocity of a black hole is greater than the speed of light.In fact, that’s why they call it a black hole.
Obviously, if not even light can get out of a black hole’s gravity well, nothing else can, either. Therefore, nothing that happens inside the gravity well of a black hole can be detected from outside. No information can leave the gravity well of a black hole, and this is why the event horizon gets its name. We can’t know of any events that happen inside it.
Bill The Butcher- What a black hole consists of; a point of infinite density, known as the singularity, at which the laws of physics might break down; and this is which is surrounded by a region of gravity so intense that light can’t escape it.
