What then is this mysterious complex component, \(i{v}_{s}\)?
\({v}_{s}\)\(\nwarrow \nearrow\) \({v}_{t}\)
\(\swarrow \)\(i{v}_{s}^{ ' }\)
The time dimension is always orthogonal to the space dimension. The direction of \({v}_{s}\) is a reference, orthogonal to this direction is the time dimension. The value of \({v}_{s}\) is not that important as far as a directional reference is concerned. One way to generate \(i{v}_{s}^{ ' }\) is to have space rotate about the direction of \({v}_{s}\), perpendicular to \({v}_{s}\). Space moving, is relatively the same as moving through space. This then makes time travel possible. Time travel in both direction, to the future and to the past, as \(i{v}_{s}^{ ' }\) can be made to add to \({v}_{t}\) or substrate from it. Theoretically.
