Using classical physics arguments and observations this paper suggests that there are twelve “geometric” dimensions governing our physical universe. In addition to the four recognized dimensions of linear space and time, observational evidence is cited to re-classify angular rotations as dimensions, making rotations a property of space; not just an attribute. To complete the symmetry, a dimension of rotational time is added to the set. Lastly, it is argued that scale must be a physical property of our reality, thus adding four additional dimensions and completing the set of twelve. Like negative and positive electric charge, and north and south magnetism, it is suggested that time and space are one of nature’s dualities. The “arrow of time”, the “now of time”, and the “speed of time” are shown to be a natural consequence of the dynamic interaction between the time and space dimensions.
