Where do galaxy clusters come from - ScienceFacts

So you may be wondering why galaxies tend to form clusters and superclusters and why not just be spread apart normally right? Well in fact the gravity from all these galaxies are attracting each other and you still may ask the question why isnt the expansion of the universe keeping these galaxies apart and its because the force of the attraction is greater and because there isnt enough time for the galaxies to settle because of the lengths of the clusters, also a reason why the universe looks like a sponge.
