What is inside black hole?
A black hole is a region where gravity is so strong that light cannot escape itself.
A black hole has a boundary called the event horizon. It is where gravity is just strong enough to track light back and prevent it from escaping. Because nothing can travel faster than light, everything else will get dragged back also.
It is much more likely to emit radiation. A mountain sized black hole would give of X-rays and gamma rays, at about 10 million megawatts, enough for world's electricity supply.
