                              BLACK HOLE  A black hole is  a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon . The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole What Inside Black Hole?  Black holes have two parts. There is  the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape.   And then, at the center, is the singularity . That's the word we use to describe a point that is infinitely small and infinitely dense What happens if you fall into a black hole? A jump into a black hole is a one-way trip. Black holes are regions of space where gravity is so strong that nothing can escape them, not even light. Even before you reach the e...
