Which theory explains why gravity between two objects changes when the distance between them changes? Einstein's theory because he suggested that the more distance there is between objects, the more space-time

curves and the greater the strength of gravity is.

Einstein's theory because he suggested that the more distance there is between objects, the more space-time

curves and the weaker the strength of gravity is.

Newton's theory because he suggested that the greater the distance between objects, the greater the pull of gravity.
