I don’t know if this question makes sense, but if every cubic centimeter of the universe is expanding due to dark matter, why doesn’t that include earth? Like I’m sitting here and neither me nor my house is expanding, so is the expansion only in the vacuum of space? If so, why?

I used the 1mm per cubic centimeter as an example the actual expantion is much smaller though im not sure of the exact values.

But the answer is you, your house, the planet are all expanding. As far as I am aware gravity and the strong nuclear force holds us together against that force. Though some hypothosize that eventually the expantion rate will be great enough to tear atoms apart, its called the big rip. Edit: spelling.
