Relative theory of Einstein

Einstein made other predictions in his General Theory of Relativity. He said that in super strong gravitational fields, time passes more slowly than it does outside the field. And as gravity becomes infinitely strong, time actually slows to a stop. He also said that all laws of geometry would no longer be true because three-dimensional space would be changed and distorted. For example, the geometry rule that the area of a square is equal to its length multiplied by its width would not be true in super strong gravity.
Einstein’s other great theory, the special Theory of relativity, predicted that the passing of time and the measurement of distance change as movement becomes faster and faster. The effects of this become noticeable only as the speed of light is approached. This would have the consequences for black holes, since objects that fall into black holes would begin to go as fast as the speed of light.
