Considerations of causality dictate (Bekenstein 1992) that the special direction undergoes a smaller stretch than the average over all directions. This particular sign turns out to be critical in the results to be described presen ...

... How does Earth’s force field work? If you throw a ball in the air as high as you can, it always falls back to Earth. At every point along the ball’s path, the force of gravity pulls down on the ball, as shown in Figure 2A. In fact, at every point in space above or at Earth’s surface, a ball is acted ...
