Thanks for that, Allen. The problem we would face is that the acentrists claim to know the rate of rotation of the World to a thousandth of a second and these motions are, as you know, specifically calculated to make their model fit observations. The other thing that they rely on is invoking huge distances to the "background" stars (this is how they attempt to wriggle out of the celestial poles argument). I am working on something in GU2005 at the moment which should prove our position once and for all (if it works!). This is one of the two main reasons for the delay in releasing the model. Best wishes, Neville.

I quote "..if the earth has all the gyrations and motions that science claims it has then the return of a point on the earth's surface to the same place in space would not periodically occur, or at all. After all, that point along with the whole earth, would have wandered off far removed from where it had been a day before."...." it was precisely this point that Vera Rubin's group were horrified to discover"...Rubin V. C. et al 1976 Astronomical Journal 81: 687-718... I can send you this paper if you like however it is 2.55 MB Gif images from the ADS database.....?. I thought about you and Steven demonstrating the difference in the observations of the background stars with respect to a geocentric and a-centric frame of reference? could this periodicity issue contribute to your model? .. and if so is this some thing t hat you and Steven hope to be able to clearly demonstrate in GU 2005? allen --------------------------------- To help you stay safe and secure online, we've developed the all new Yahoo!
