    I saw an article in New Scientist...

    This is a piece from it.

    OUR universe appears to be unfathomably uniform. Look across space from one edge of the visible universe to the other, and you'll see that the microwave background radiation filling the cosmos is at the same temperature everywhere. That may not seem surprising until you consider that the two edges are nearly 28 billion light years apart and our universe is only 14 billion years old.


    My question is this, wouldn't that just be a description of a spherical universe, the two numbers mentioned kind of hint at that. 14 billion is 1/2 of 28 billion, so if the universe is a sphere, then the origin of the microwaves would be the center of the sphere and yes it would be uniform throughout. If the sphere had a finite edge of some sort then the radiation would stay at some steady state, whatever. I am sure there is someone here that can through some visible electromagnetic radiation on this!
