# Three arguments for 3D time

There are three main arguments for time having three dimensions:

(1) The speed of light is a conversion factor between space (distance, length) and time (duration, length of time). In transportation there are less exact conversion factors in the typical speeds associated with different travel modes. Since space is three dimensional, its conversion into time is also three-dimensional. The scale of maps may be in units either of distance or of duration using a standard conversion speed.

(2) Observation follows the movement of light, which is three dimensional. In astronomy it is often said that observation of the sky is a way of looking into the past. Observation is a form of communication and any type of signal (sound, mail, etc.) will suffice though not as exact as light. As the observation of space is three-dimensional, so the observation of time is also three-dimensional. Maps of time are similar to maps of space: they show observations (signals) in different directions.

(3) Movement in orthogonal directions entails moving in three dimensions. Each dimension of movement has an average speed from the change in space (length) divided by the change in time (duration). As movement is in three dimensions, so the time aspect of movement is in three dimensions. Travel shows the same result. Maps of movement may show either spatial positions or temporal positions or both.

Each argument may be illustrated by a map. The conversion factor argument shows how any map may be scaled in units of space or time. The observation argument shows that maps of observations have units or space or time. The movement argument shows that maps of movement may show space or time or both.

Note that every argument has an analogue in ordinary travel and so is not unknown to nonspecialists. The arguments are however exact in the case of physics.
