For a lay person such as myself, it's very easy to get confused and stumble around a bit, trying to understand how galaxies can be receding greater than the speed of light when the speed of light is the cosmological speed limit. It's easy to make the mistake of saying 'Ha! There are whole galaxies breaking the law'. I'm trying to develop a bit of intuition for this. I take it that I should understand that expansion doesn't grant motion. I like the balloon analogy, it's helpful but I have trouble getting past the roundness of a balloon. So, I tried imagining something flatter and went for a pair of nylon stockings in the wife's bureau. Imagining grains of sand stuck to the threads as galaxies and stretching the fabric, it's easy to get a sense for how celestial bodies keep their coordinates and the laws of physics are preserved. It's just the metric of those coordinates that is changing .. no 'new' energy or motion. Am I on the right track, or just out there flapping?
