Einstein made some rock-solid predictions. His theories predicted that the collision of massive objects would create ripples in spacetime called gravitational waves, which we detected in 2015. They also predicted the existence of black holes, one of which we imaged this year. But they also made predictions for phenomena that haven't turned out to be real — at least, not so far. One of those is the white hole, the theoretical opposite to a black hole. While they've never been shown to exist, some scientists think they could explain some of the universe's most unexplainable characteristics.
