Our milky Way galaxy is one galaxy in a huge cluster of galaxies that are all bound together by mutual gravitational attraction. This collection of galaxies is called the “Local Supercluster”. There are many superclusters in the universe; the Local Supercluster is the one that we live in. The Local Supercluster is approximately ball-shaped, with a diameter of about 100,000,000 light years. The Milky Way is representative of the typical size of a galaxy in the Local supercluster. Make a rough sketch of the Local Supercluster. Choose a scale as you have done before, – 5 – so that it will fit on this page. Place the Milky Way near the edge, making sure that it’s diameter is approximately the correct size relative to the size that you have drawn the supercluster. Add ten more Milky-Way sized galaxies (to represent the actual thousands of galaxies) randomly placed in your supercluster. Show all calculations.
