1. How did the distance from the "home" dot to each of the other galaxies change each time you inflated the balloon? (reference your data and what the data indicates)
2. Which galaxies move the greatest distance , the near "home" or those farther? (reference your data and what the data indicates)
3. If you deflate the balloon completely, simulating the beginning of the expansion of the Universe, what happens to all the galaxies? What would this point in your model represent?
4. How is your model similar to reality and how is your model different?
