This book describes a theory of Elementary Particles and Gravitation called the Quaternion Unified SuperStandard Model (QUeST) and provides a detailed derivation of its basis from a fermion-antifermion annihilation in the Megaverse - the universe of universes. It also shows that features of QUeST and the Unified SuperStandard Theory (UST) are derived from an initial fermion-antifermion pair. The combined theory also derives the Megaverse from a fermion-antifermion annihilation in a 10 dimension hidden space.

Thus there is a chain of theories from the 10 dimension space to the Megaverse to the QUeST universe to the UST. The cumulative effect of the combined theory takes one from creation to the physics of high energy particle accelerator experiments. And it all begins with the hypercomplex numbers: quaternions and octonions.
