Abstract
The only observed relationship of time to space is a reciprocal relation, in the equation of motion. However, it seems absurd to think of space, defined as a set of points satisfying the postulates of geometry, as the inverse of time. Only when we view the observed increase of time, as the 0D inverse of the observed increase of 3D space, does it begin to make sense: The expanding universe is an expanding set of four-dimensional spacetime coordinates, just as Einstein conceived it, but this also may be its initial condition. The expanding block universe of spacetime, generated by a four-dimensional space^3/time^0 progression, is the simplest hypothesis we can make. If we make this assumption, then the remaining task is to understand how to introduce radiation, matter and energy, with their observed properties and behavior, into the 4D spacetime picture. This essay outlines the approach of one attempt to do just that, in less than 5000 words.
