One million miles per hour relative to what?

Edit: I see from Wikipedia that it is relative to the cosmic background radiation (which I congratulate myself on having sort of guessed).

Edit 2: Oh wait. The article says that the flow dates back to the first fraction of a second. But the origin of the cosmic background radiation is much more recent than that. So I'm still in baffled.
