Relativistic addition of velocities in a five-dimensional spacetime — •Roland Alfred Sprenger — Herford, Germany

Another method of adding relativistic velocities is shown. It uses a fifth dimension of spacetime rotating the coordinate system of the Minkowski diagram into it and thus is an indication of the existence of a fifth dimension. As proof of correctness of the rotation method it is derived from the addition theorem of velocities. Photographs of a hardware model and diagrams of a computer-generated model illustrate how to find the resulting velocity by the rotation into the five-dimensional spacetime. Alongside the paradox is resolved that any velocity added to lightspeed results in lightspeed.
