A 3D grid of stacked intersecting lines, representing the "fabric" of space. In one area, the grid is flat (empty space). In another, the grid is distorted (near a mass eath or sun) and shows the grid being absorbed by the mass. left side just shows the empty grid the right side shows earth and that earth is absorbing all the gridlines around it.left side hascaption empty spacetime right side has caption near a mass Mehr sehen
