Some might ask: in a universe without absolute motion, how could we end up with such a result? How come the CMBR isn't isotropic in other frames? Why is the universe effectively singling out that supposedly unspecial frame?

IT ISN'T! Jesus christ...every now and then this idea crops up.

So is the CMBR also isotropic in all other frames?

It is just an electromagnetic background. It is only special becuase
we believe it to have been created shortly after the universe was
created.

Yes, I know what it is. It's the greatly red-shifted glow of hot gas.

But what I was pondering was this: How do we get from a universe with no absolute motion - in which there are no special velocities - to a universe with such things as the CMBR? Like I said in my original post, at each point in space, there's a particular frame in which the CMBR is isotropic. If there are no special velocities (no absolute motion), how come the CMBR is only isotropic in certain frames?
