Philip,
Thanks for reading and commenting. You do indeed understand my argument. The basis for this thinking is Equations 5, 5.1, and 5.2.
I consider motion to be the best explanation for the observed red-shifts associated with distant galaxies. Therefore, I think that the observable universe was much smaller in the distant past. Whether it began as (a point followed by inflation then expansion) or as (a homogeneous sphere followed only by expansion) is less clear to me. It is hard for me to imagine a sphere that is so large being almost perfectly uniform. So, I favor the point beginning but I have some doubt.
My knowledge of modern cosmology is fairly limited. As I understand the situation, we observe that almost all of these galaxies are moving away from us. Given the errors of our prior earth-centric thinking, we interpret this to mean that there is no center of the universe and that everything is moving away from everything else. This argument seems to me to be flawed. The simpler explanation is that there is a center to the universe and that everything is moving away from the center but doing so at various velocities. So, the fact that so many galaxies are moving away from us simply means that we are moving slowly compared to most of the universe.
I would envision the expansion of the universe as being driven by the complex quaternion terms present in the Octonion Group. Essentially, I see those terms as being virtual electrons. Since like charges repel, the universe expands.
