Well, I’m using accepted terminology. Those regions are causally disconnected from us.
They're not causally connected to us here. But if you move further you'll see more. So it's causally connected to other parts of the universe that are in range. I'm talking about things that are not causally connected to our universe at all i.e. other universes, so that there is no way to detect them even in principle, regardless of where you are in our own spacetime.
