The universe is made up of 2 types of matter: baryonic matter, which is made up of atoms, and dark matter which is not. Fritz Zwicky hypothesized that galaxies inside the Coma Cluster were being held intact by dark matter. Scientists believe that galaxies would break apart if dark matter were absent, causing the structures of the galaxy to fall apart.

So the correct selections are:

1. baryonic
2. dark
3. dark
4. dark
