Asked by Jeremy Blunkett
While we believe it is impossible to travel faster than light, if you were to move at a velocity close to it, you would likely still cast a shadow. Racing at these speeds, the shadow we would create could potentially exhibit some slightly unusual behaviour.
As a shadow is formed when light is blocked, travelling close to the speed of light would cause you to move a significant distance in the time it took for the unblocked photons to form the outline of your shadow. As a result, your shadow would be likely to lag behind you.
