If we scale the approximate size of the Sun (~1 billion meters) to fit onto a DVD (about
100mm or 0.1m), how many DVDs would you have to connect as a chain to represent the distance to the nearest star? Use the fact that Alpha Centauri is about 10¹⁶ meters away from Earth. Hint: determine the scale factor which reduces the true size of the Sun to a DVD and apply it to the distance to Alpha Centauri.

If you started this chain of DVDs in Ann Arbor, what city in Michigan could you reach?
