Description
Attempts to account for the elementary properties of matter through a structure of extra spatial dimensions date from the theory of Kaluza 100 years ago. In more recent years, while there is still no clear evidence that extra dimensions of space exist, the origin of the structure of the Standard Model has become a central question in fundamental particle physics. We describe how a new approach, with a further generalisation from the local 4-dimensional spacetime geometry to a general form for proper time, leads directly and efficiently to Standard Model structures. This generalisation naturally makes use of unique mathematical structures involving the octonion algebra and the exceptional Lie groups that are also seen in some SUSY models. As an additional feature of the theory a natural candidate for dark matter, itself a further major mystery in physics, can also be directly identified.
