So, we say that the cosmological principle holds. There is, of course, vast evidence for this. See here for a fuller discussion. And, thanks for your congratulations! It's the members that I should be thanking, though, for the interesting posts I've seen to respond to!

Thanks Neutralino for the link. And starting this tread for me.

Do you realize that you gave me a link that says, if I was to state that Galaxies where residing to a centre, that my theory is as possible as any other. For all theories are limited to the scale of our observable Universe.

I especially like the example of Galaxies A, B, and C. If the words 'moving' were changed to 'receding', and the Galaxies were said to travel at an ever increasing speed as they move closer to the center, would not the example work the same.
