time is simply not a dimension, no matter some diagrammatic representation; it is awareness *of* dimensionality; if one has no awareness of universe, one cannot do any of the God-am *mathematica* (any of the four subjects, or quadrivium, including Gauss's "queen of the sciences").
how can Kooby Doo not have any hypothesis, but a bunch of allegedly corrective math -- what is the hypothesis, KD?
spacetime is nothing but quaternions, as shown by Einstien's assistant, Lanczos, in _Variational Mechanics_ from Dover, a vast treatise on configuration spaces.
