The simplest way to organize the information is to place things into two distinct piles, one which contains things that are known (proven), and another separate pile that contains speculation or theories that may or may not have merit. Since the entire topic is novel, there are no existing goalposts that can be applied in order to formulate this partition. Therefore, we can only make the logical distinction between the actual mathematics (mostly trigonometry and algebra which we know to be correct) and the speculative applications for the math with regards to physics.
The math appears to be an expansion of spherical trigonometry. This mathematical expansion expresses a relationship between the radius of a small circle on a sphere to the slope of a tangent to that circle relative to the sphere. The physics appear to be concerned with certain solutions that this expansion and extension of spherical trigonometry can produce for defining spacetime.
The fundamental function underpinning the whole concept is an expression of a unique relationship that’s created by the framework of three orthogonal axes, or perhaps three orthogonal planes. These are the normal axes that we are used to, the ones that exist in Euclidean 3-space, or what we know as the Cartesian coordinate system. The three-dimensional framework contains relationships that don’t occur in two dimensions. Heretofore these relationships have gone unnoticed.
