This book shows Cosmos Theory is directly based on a mathematical fact: the number of independent anti-symmetric tensors of 0, 1, 2, ..., r indices in r even space-time dimensions. It removes the impression of some that Cosmos Theory is merely an aggregate of features without a sufficient cause. It proceeds to show that Cosmos Theory emerges with a structure similar to Hilbert curve construction. The resulting Cosmic Curve has analogous features: the nesting of dimension arrays within dimension arrays and so on. The size of dimension arrays is set by the number of independent anti-symmetric tensors, which is a multiple of the number of creation and annihilation operators in a fermion in the various spaces. The result is a similar structuring of the Cosmos Curve, of dimension arrays, AND of the gamma-matrices in our universe and in higher spaces. They all display nested structure. The book presents a concise description of new and of known Cosmos Theory features. The fractal Cosmic Curve supports a unique Language that the book describes. It also introduces a new SuperCosmos Theory that is a fractal curve construction whose elements are Cosmos Theories.. A major leap in the understanding of Cosmos features and their origin!
