Kay-space theory is an attempt to provide a one to one correspondence between elements in a mathematical structure and what are conceived as events in the universe, so that composite structures also correspond and analyses in the abstract mathematics clearly relate to the universe. Commonalities are found with existing theories, some of which, together with experimental results, were influential in the development of Kay-space theory. Due to the extensive details within the theory, it could be considered ‘self-interpreting’.

Kay-space theory does provide a number of predictions, mostly in the form of expected influences and tendencies, as well as likely sub structures of fundamental particles such as photons, electrons and quarks, whose existence and functions in atoms is also accepted in the standard model. In some cases, the predictions are numerical and are encouragingly close to experimental results.

It should be said that general relativity and Kay-space theory have strong similarities in that the presence of matter influences space-time which in turn influences the movement of matter. Kay-space provides the cosmos with an additional very large dimension named “bigR”. The common three dimensions which form the surface of an expandable four dimensional shape are based and dependent on long narrow high speed ‘metric arrows’ which keep matter and its movement ordered in space. These metric arrows, named meils, can and do act as message carriers (rather than force carriers) and largely selectively interact with matter without otherwise impeding its movement. In fact, certain interactions between matter normal to the meils result in what is perceived as the inertial property of matter. Moving matter is accompanied by soliton waves in the meil net, which is typically considered as space-time. Gravitation is an interaction between matter and meils in line with the direction of movement of the meils which temporarily shortens the distance between the meil heads and tails. Gravitational and inertial interactions are generally found to be linearly proportional in magnitude.

Quantum mechanics and QFT are highly respected for being able to provide such accurate predictions. The pilot wave interpretation is found to fit Kay-space theory much closer in principle than the Copenhagen interpretation. The uncertainty principle is argued to largely have its origin in that the small particles are not point particles but have both finite size and a sub structure. Kay-space theory has not reached a stage where many calculations are being made which allow direct numerical comparisons. Similar mathematical tools as used for wave functions in QFT can be used to study the time dependent motion of the flexible rings whose local radius of curvature is related to the electric potential.
