I think you will see object in front of you and behind you as accelerating away from you, but you will see object to the left and to the right going toward you.

jaques,

That would seem to be the case at first glance but then recall that when played in reverse the rising bread analogy there is no such difference in what we see as recession, so an accelerting reversal of the process should look the same.

The biggest question that comes to mind is that as viewed macroscopically (seeing the loaf as an observer) the loaf is shriking and the rasins are getting closer, the CMB would be increasing.

However as an observer on one of the rasins the rasins all around you would apear to be receeding and the CMB should be decreasing.

How does one reconcile these two different views of the CMB?

PS: One Note: The concept of a loaf should also be the same geomety as the ballon, only have material in the volume not just the surface.

I don't know. You need to explain me that>

May be you're thinking of gravity: an accellerating contraction.
Inside the gravitationnal limit we can see objects comming thoward us and away from us. Outside the limit objects seem to go away.
What do you think of: Explosion AND Implosion ?

I don't understand your question.

As far as the thought experiment goes:

If the loaf were imploding and the implosion has an acceleration component, then an object between you and the center of the implosion would be moving toward the center faster than you and you would see it receeding. Likewise an object beyond your jposition but also moving toward the center but being slower than you would apear to be receeding.

We know from the description of the experiment that all objects are moving in a common vector toward the center and the background energy density should appear to be increasing. The question then is how does this background energy increasing reconcile with the fact that as an observer you see expansion, not contraction?

I can see that but what about thing on the other side of the center? What about the other thing to the left and to the right going at the same speed as you toward the center?
I mean by Implosion and Explosion that there are an outwad motion and inward motion at the same time in the universe. Inside gravitationnal limit we experience an inward motion but outside of the limit we experience an outward motion.

We are not in disagreement here. I am not suggesting that we are imploding in lieu of exploading. The object to the side along the same radius that you occupy would indicate implosion.

The question being asked is how does one resolve the CMB (Background Radiation) issue. We know we are imploding and the CMB should be increasing but observationally we think we are exploading (in the
radial line of sight) and the question is will the CMB appear to be increasing or decreasing in that vector.?
