I'm only coming back here very occasionally so don't count on any quick replies.

Well, I still hope to see you around more :)-> In the original post B-M wrote: "If you measure the time it takes for readings from the CMRB to reach a given point, then work backwards to a point where the time from CMRB X+,Y+,Z+ = X-,Y-,Z- you should have origin=X,Y,Z =0 which gives you a universal frame of reference."

> B-M appears to think the Background is the "edge" of a "present" spherical three-dimensional universe within which we are situated.-For all practical purposes, time is simply another axis along which we measure, 4 dimensions instead of 3. Additionally, time, much like space, can be compensated for mathematically, and in fact must be accounted for in some fashion all but the simplest of equations. No, the universe is not(most likely) a sphere, ellipsoidal perhaps, but not likely spherical. However, even if it were tetrahedral or a parallelogram or any other deformation you can conceive of, the concept could still work, even if it required measurements along more axis. And while we are looking back in time, we are also looking across distance. Can you at least concede that the universe, based on the fact that we can see the CMBR throughout the whole of the sky, must be limited(even if it is expanding), and if it is limited, it will contain properties such as volume and boundaries?
