In 1905 when Albert Einstein first attempted to perform a Lorentz transformation on Maxwell’s equations, he left deliberate gaps in the spacing between the terms of the equations when they were presented in their transformed state. Careful scrutiny will also reveal that Einstein couldn’t actually have got the results that he did by using the method which he claimed. The mysterious gaps seem to be alluding to a symmetry in four dimensions. It was almost as though he was saying “this is what the solutions should be, but I can’t get there using three-dimensional algebra”. It will now be demonstrated that it is actually the non-relativistic part of the Lorentz transformations, and not the relativistic Lorentz factor, 1/√(1 – v2/c2), which betrays the existence of a 4D space-time continuum.
