Once you have quantum field theory, it's a little bit trickier. So once you have both quantum field theory especially and also gravity, so that you have space-time curvature, then it can be trickier. So we talk about not only the vacuum locally, That is to say, here I am in some finite region of space and time, and I look around and there's nothing there. And I can describe what is going on.
