    Apparently it is just the slightest bit warmer on one side. It’s called the dipole of the cmb. I don’t fully understand it, but as far as I know astrophysicists don’t understand it either. ;-)

      But how would you use the dipole to specify where you are? Isn’t the dipole the same everywhere? I’d think the dipole could possibly specify a fixed direction, but that’s hardly enough to specify a fixed point referencing only the CMB.

        Huh, you’re right. I guess at a position you can use it to define a point. A point where you don’t move in any other direction.
