We live in an expanding Universe, correct? What, exactly, is the Universe expanding in to?
It's not expanding into anything. it's just expanding. Because the universe is already *everything*.
That's quite an admission, to admit that the Universe is expanding but not at the expense of something else. When I blow up a balloon, it has a spatial center and a center of mass, but as the balloon expands, it displaces the atmosphere around it.
Not so with the Universe; as I said, quite an admission on your part.
