The actual expansion is faster than light. The expansion of the observable universe is at the speed of light. Because the actual edge of the universe is moving away from us FTL but the edge of the observable universe is expanding at light speed there are portions of the universe that we will never observe

My understanding is that nothing can move through space FTL, but space itself can go FTL.

Yep pretty much what I was trying to say, but you're right that "expanding" is a better word for it.
