The alternative theory for the evolution and existence of the Universe presented here, just like all such theories, must, in view of the lack of observational support, be regarded as speculative. However, in its favour, it is based upon an existing universal phenomena, gravitation, and has been demonstrated to be mathematically sound. As such it does not rely upon exotic events such as spontaneous creation on any scale from some unknown source of energy. Also it does provide a very good theoretical estimate for the one sound observational fact, the Hubble constant of the recession of the distant galaxies, albeit this parameter is very difficult to measure.

It is also evident that the new theory does in fact contain some elements of both of the existing models. The original Steady State theory is to some extent embedded in the existence of everything outside the physical Universe. This continuum is believed to be Pseudo-Euclidean in nature and contains everything from which our Universe, and possibly others, are created and eventually disperse into. The difference is that spontaneous creation of matter is not a feature. Its near infinite spatial and temporal existence being quite self sustaining without the necessity for such bizarre events.

The "Big Bang" theory is essentially embodied in phase II of the evolution of the Relativistic Domain Universe. The similarity is augmented by the inclusion in the "Big Bang" theory of such ideas as the anti-gravity feature of dark energy and quintessence. There the similarity ends however, because of the nature in which these characteristics are generated. The spatial contraction/material expansion process of phase II of the evolution of the Universe in this new theory does not emanate from the sudden spontaneous creation, from absolutely nothing, of any form of energy or space-time continuum, or the existence of an exotic virtual particle quantum energy field. Instead it results from the simple reversal of a universally natural phenomena, gravitation.

As a result of the theory presented here, the possible resulting age of the current Universe, as roughly estimated at some 45 billion years, is considered much more in keeping with the potential age of some of its more unusual constituents such as the very distant Quasars etc.
