This metaphor ties in neatly with the quantum aspects of the Pyramids: rubber sheets distorted by balls are one popular way of visualising Einstein’s general theory of relativity. The sheet represents the space-time-continuum, and the balls are bits of mass (like suns and planets). The balls press down and deform the space around them. When things try to move along the rubber sheet, not only are they attracted into the dimples in the sheet (gravity), but things like light which try to travel in a straight line find little kinks in their path around an object.
