The mathematical abstraction of geometry has a good fit to physical law. A pair of very basic geometric forms can be linked to mutually define the size of the most basic units of measure, a unit length and a unit time duration and produce a mathematically defined value for the speed of light. One does not need to know ahead of time the actual physical size of the dimensions used to describe the elements of the triangles. The result of the paired geometric process identifies the perfect union between space and time.
