Gravitation and Cosmology :, (C1 Ver. 2.2.1) - Following a brief critique of existing classical theories, this paper extends Relativistic Domain Theory into cosmology to develop a new theory for the origin and existence of the Universe. This development, by treating the Universe itself as a unique gravitational source, is based solely upon both the existing, and a new gravitational phenomena. The main feature is the derivation of a theoretical relationship for, and corresponding numerical value of, the Hubble constant, which is then compared with published empirical results and demonstrates agreement to within 18%. The new theory also provides an alternative estimate for the age of the Universe of approximately 45 billion years.

Close Proximity, (C2 Ver. 1.2.1) - This paper investigates the effects of the physical radius of a large gravitational source being of the same order of magnitude as its Gravitational radius. It also investigates an empirical law relating the mass and radius of gravitationally accumulated matter. An estimated mass for the newly discovered planetoid Sedna has now been added as an additional Appendix.

Gravitation and Cosmology II :, (C3 Ver. 1.4.0) - Carrying on from the first paper in this category, further development of the evolution of a Relativistic Domain Universe is effected here. The emphasis is on the first Phase and the initial part of the second. A discussion of the manner in which a definable boundary is established in the first Phase, is followed by a derivation of the characteristics of the accumulation of celestial matter at the Universe's core. The development of the dynamic relationship between the radius of the physical boundary and the Gravitational radius is then developed. Finally, characterisation of the whole process is completed by the derivation, in the initial part of the second Phase, of the radius of the point of inflexion.

The Origin and Existence of the Universe - Development of Full Dynamic Characteristics. (C4 Version 1.0.0) - This paper presents the full dynamic characteristics of the Universe as represented by Relativistic Domain theory. There are eight parameters explored, covering such topics as the diameter of the Universe today, and the position of the Milky Way, (Earth), within it; galactic recession velocity and acceleration rates, and the Hubble parameter and its gradient and temporal variations; and finally, the variation of temporal rates, and the speed of light. Where possible comparison with "mainstream" theory is also effected.
