Discussion Questions:

1. In class and this weeks news articles we learned how to use black holes as a way to time travel into the future. Suppose that there were some other way to travel into the past instead (NOTE: You would not be able to do this using a black hole!). If you could make the trip safely, where in the past would you go to, and why?

2. Black holes are easily one of the most popular types of objects discussed in introductory astronomy classes, and theories and observations regarding black holes appear in popular-level news articles very frequently despite their general rarity, small size, and exceedingly small impact on Earth-focused astronomy. Why do you think that is the case?
