Weird question I just thought of: if space is always expanding, why aren't the objects around us, even their very atoms, getting slowly torn apart? Are the forces holding them together just constantly pulling them back together? Is it just a very small amount of expansion at a human scale? Does this affect very sensitive measurements of distance?

Both. Even our galaxy is held together by gravity that's stronger than the expansion of space on that scale.
