This Second Edition of The Unified SuperStandard Model and the Megaverse deepens the basis of the theory as presented in the First Edition by introducing a factorization feature for fermion and boson second quantized particle fields. The factorization procedure is motivated by two significant features of The SuperStandard Model (and The Standard Model also): the Complex Lorentz Group has a set of subsets that match the factors in the SuperStandard Model's symmetry suggesting that there is a Complex Lorentz space for particles as particles; and the instantaneous feature of Quantum Entanglement that suggests all parts of separated particle states are related by a mechanism beyond convetional quantum field theory. We suggest that each particle field is an inner product of a functional from the space of all particle functionals with a corresponding coordinate fourier quantum field expression. We view the particle functionals as commuting and as located at a single (mathematical) point. Thus a quantum state with separated parts in coordinate space has their functionals at the same point in functional space. A change in one part of the quantum state (in its functional(s)) instantly changes the functional(s) correspondingly in the other 'distant' part of the quantum state. No 'spookiness!' The author points out that there is no other possible physical mechanism for entanglement instantaneousness. The introduction of quantum field factorization 'explains' the similarity of Complex Lorentz group subgroups to Standard Model groups factors. This new deeper level yields The SuperStandard Model as described in the First Edition as well as furnishing a deeper explanation of SuperStandard Model group structure and resolves Quantum Entanglement 'spookiness', which the author views as an important sign of the need for quantum field factorization. The Unified SuperStandard Model contains the known features of fundamental elementary particles, and their interactions, plus additional new features, derived from first principles. The Second Edition contains the material in the First Edition and adds new depth, and significant amounts of new information, as well as correcting typos.This book clarifies, extends and revises parts of The Unified SuperStandard Model and its extension from our universe to the Megaverse of universes. The naturalness and simplicity of the derivation from first principles (primarily Relativity) leads us to suggest that the derivation is correct. More importantly, the directness of the derivation to a unified theory encompassing the known features of The Standard Model of elementary particles and Gravitation also enables us to exclude possibilities that might have been conjectured for elementary particle theory and gravity based on their unnaturalness within the framework of the derivation.
