Can we see the arrow of time? Algorithm can determine, with 80 percent accuracy, whether video is running forward or backward |

Einstein's theory of relativity envisions time as a spatial dimension, like height, width, and depth. But unlike those other dimensions, time seems to permit motion in only one direction: forward. This directional asymmetry -- the "arrow of time" -- is something of a conundrum for theoretical physics.
