The special theory of relativity limits the speed at which all such influences can travel to the speed of light, {\displaystyle c} c. Therefore, the principle of locality implies that an event at one point cannot cause a simultaneous result at another point. An event at point {\displaystyle A} A cannot cause a result at point {\displaystyle B} B in a time less than {\displaystyle T=D/c} {\displaystyle T=D/c}, where {\displaystyle D} D is the distance between the points.
