I've heard that we've known components of the universe appear to be flying apart faster than $c$, and that this can happen because the space containing these materials are also moving apart.

How does someone move space? How efficiently can it be done?

I would like to get on a rocket and then move the space very close to Sedna and see what it looks like. What are the physical barriers to doing that?

As I understand it, the space is not actually moving, but expanding; Which means that objects in this space are "moving apart".

Now, "moving apart" has not much to do with the physical term of moving.

Essentially, one does not move space because that makes no sense; Not because it is impossible.

(Or, more poetically: It is not even impossible to move space.)
