Space is expanding at the speed of light? Okay... whatever you say. Go look at old buildings. They occupy space. Why aren’t they falling down because the space inside them is expanding?
Where did I say that, although it could be the case at some distant point in the future. And it wouldn't violate Einstein's theory because it wouldn't involve objects moving *through* space faster than light (apparently impossible), but rather space-time itself being created faster than light.

Space expansion is only occurring, or observable, at the grand scale of the regions between galaxies and so forth.
