Am I right in thinking that when we look far away from our galaxy other galaxies seam to be accelerating away from us but locally things accelerate towards each other?

If so, if you take a network of inter connected points and start them off randomly connected to each other. Then over time choose a point and remove one of it's links and replace it with a link to a point that is closer to the point than the one previously linked to.  Over time what would happen is that local clusters would become more interconnected and so closer and distant clusters would become less connected and  further away from each other. I realise that there are a number of different ways of measuring distance in a network but I think the result would be the same regardless.

Could a mechanism similar to this one be responsible for the gravity / dark energy problem?
