This explanation is awesome! So I have a question. Is it only SPACE that is expanding and not the objects within it? Does my body expand 74.2km in every direction every second, but I don't notice it because everything else expands too? In your animation, it appears that planets and galaxies size remains the same and only the relative distances between them changes. Can you clarify?
