The galaxies are moving across the water. Space moving would be like balls placed on a bed sheet and the sheet expanding. The galaxies aren't moving- the sheet is. What's actually happening is more like galaxies moving around on a sheet that's being pulled further at all sides.

How can you tell the difference?

things are moving away from other things the faster the farther away they are, uniformly across the universe. everything is moving away from everything, not just two particular points.

is there a difference if there isn't a difference?
