This is what a physicist friend sent to me a while ago: "there is really little point in trying to graphically represent anything beyond spacetime. Possibly 3D space with a time vector is useful (i.e. an object representing 3D space moving along a vector) because it is still helpful to explain the concepts. Beyond that just stick with the numbers or you risk confusing yourself on what is being talked about"
