Gravity in higher dimensions
Gravity from a massive body stuck on a brane. The brane dimensions are represented by the single vertical dimension on the page, while the extra dimension is along the horizontal direction. When the bulk is compactified, the body can "see" images of itself gravitationally. Close to the original body, space is bent radially and gravity looks five dimensional. Far away from the body, however, space is bent equally by the body and the infinite line of mirror images. Gravity becomes four dimensional and behaves as it does according to the 1/r2 force law of our everyday experiences.
