United Universes

A more complete united theory of our universe and the enclosing Megaverse based on QUeST and MOST. These theories are based on quaternions and octonions respectively. Noteworthy features include four sectors of fermions and interactions - three of which are Dark; a Darkness quantum number and Superselection law preventing interactions among the four sectors; particle - dimension duality, dimension - particle - functional triality; octoquarks in 8-dimension space; a spin - Darkness connection; and a clean connection between our universe and the Megaverse.
