Presented here is how the physical theory approach of theoretical physics can be demonstrated to be incomplete in explaining physical phenomena if indeed physical phenomena have key dimensional components that extend beyond the dimensional time-domain of time-now; although the past and the future cannot be proven to exist, for one has happened and the other has yet to happen, and reality is primarily defined physically in the time-domain of time-now as the action-principle realm, proposed here is that the idea of time-before and time-after should be if not are essential to a complete understanding of time. It follows therefore that to propose time to be linked with space as spacetime is to restrict one’s theoretic understanding of time and space to the datum reference of time-now and thence not acquire a full account of the theory of physical phenomena. This issue though is resolved with a philosophical analysis of time in extending the dimension of time to the virtual time-before and time-after time-domains consistent with our conscious ability of time, and then labelling such with a zero-dimensional mathematical theorem, by which process a resultant mathematical theorem can then more thoroughly explain the physical phenomena of time-now that the physical theory approach in physics has aimed to define.
