Abstract
Space-time is divided into several regions split by the light-cone into domains: within the light-cone we have a) The future domain we can influence by our actions; that is, where we could send information to or even travel to; and b) the past domain which has influenced our present state. Outside the light-cone we have the acausal domain that we cannot communicate with at this instant in time. The light-cone coordinates are introduced as a mathematical tool that relates to the space-time division.
