Prediction of dark matter using six-dimensional special relativity

The existence of dark matter is predicted using the theory of six-dimensional special relativity. Because of the richer structure of the null surface in a higher-dimensional theory, it is shown how a particle can become invisible to an observer when a certain condition is satisfied, because the world line of the particle can cease to intersect the extended null surface of the observer. Using this condition it is demonstrated that matter which the observer cannot see is able to send light signals to, and hence influence the behaviour of, matter which the observer can see. It is shown that under certain assumptions of symmetry the proportion of dark matter in the Universe is (γ (V)-1) where is an average taken over a suitable distribution of speeds V. Three simple models of this distribution yield percentages of 63.7%, 78.5% and 84.9% of dark matter
