      The biggest “thing” in the universe is superclusters of galaxies, which are huge regions of galaxies attracted to each other by gravity. We are in the Laniakea Supercluster of galaxies, which is 500 million light years across: https://en.wikipedia.org/wiki/Laniakea_Supercluster

      The so called cosmic web. We think an interconnect of collapsed dark matter along which galaxies cluster.
      There is a nice simulation here:
