The universe is not is not expanding or contracting.
The parts within the universe do their contractions and expansion as we can observe in images.
Clustering is a property that we understand.
Our Milky Way clusters, all matter moving towards the centre.
Local group of galaxies cluster with M87 as the centre gravity sink.
Many other local galaxies similar to ours cluster to form a Super Cluster of groups of galaxies.
We know all this and yet people have this idea that the universe is expanding, accelerating etc.
