Black holes are the gravitational monsters of the Universe. They are so powerful that nothing, even light, can escape their grasp. One black hole is bad enough. But if you took two black holes and smashed them into each other, they'd be capable of changing the shape of space itself. How epic would that explosion be? And could it somehow reach the Earth?
