United Universes: Quaternion Universe - Octonion Megaverse

This work presents a comprehensive unified theory of the universe and the encompassing Megaverse, utilizing QUeST and MOST theories grounded in quaternions and octonions. It explores complex concepts such as four fermion sectors, three of which pertain to Dark interactions, and introduces a Darkness quantum number along with a Superselection law that governs these interactions. Key features include particle-dimension duality, octoquarks in eight-dimensional space, and a unique spin-Darkness connection, establishing a clear link between our universe and the Megaverse.
